Description

  

  

    The BD Lyoplate™ Human Cell Surface Marker Screening Panel contains 242 purified monoclonal antibodies to cell surface markers. The panel also contains both mouse and rat isotype controls for assessing isotype-specific background. The panel can be used for screening cell lines, primary cells or tissue, and is compatible with flow cytometry and bioimaging technology platforms. The panel contains three (3) 96 well plates, each well containing 2.75 µg of antibody, enough for five tests (0.5 µg/test) along with AlexaFluor® 647 conjugated goat anti-mouse Ig and goat anti-rat Ig secondary antibodies. This product is compatible with cells expressing fluorescent reporter genes, such as green fluorescent protein (GFP) and can be used with additional antibodies that recognize cell surface and intracellular molecules. Positive hits from screens can be followed-up with either purified or flurochrome-conjugated antibodies offered by BD Biosciences.

    It is important to note the antibodies present in this panel may not recognize all isoforms of each cell surface marker. In addition, antibody clones can behave differently on cell types depending on the availability of epitopes present, i.e., certain epitopes can be occluded by post-translational modifications. Results you obtain in this screen may only be relevant to the antibody clones tested.  

Recommended Assay Procedures

    Important instructions before you begin:  

  

  

  

    ·        Do not remove the plates from the foil bags until they are ready to be used. The foil bag is the primary moisture barrier. Once the         plates are removed from the foil bags, the antibodies must be reconstituted.  

  

  

  

    ·        Before removing the foil seal be sure to spin plates and also use caution when removing foil seal. Please see "reconstituting the         antibody" section below for details.  

  

  

  

    ·        After the foil seal is removed and prior to reconstitution, avoid placing the plastic lid or any cover on the plates or resealing the         plates with an adhesive-based plate seal. In each case, the resulting static can cause the cakes to dislodge and escape from the  

  

            wells.  

  

  

  

    ·        You may notice that not all lyophilized cakes have the same physical appearance. This is expected and will not affect performance                 of the antibodies.  

  

  

  

    ·        Some cell surface markers are sensitive to enzymatic digestion. When possible use a non-enzymatic cell dissociation buffer for preparing   

  

            cells for flow cytometry. For enzymatic cell dissociation of cell lines we recommend using Accutase™ (Cat. No. 561527).  

  

  

  

    ·        Ensure that cells are in a single cell suspension. A DNase treatment step and addition of EDTA to BD Pharmingen™ Stain Buffer (FBS)         (Cat. No. 554656) will mitigate cell clumping.  

  

  

  

    ·        Some antibodies to cell surface markers can produce artifacts (false positives and negatives) on fixed cells. If fixation is necessary, staining   

  

            live cells with subsequent fixation prior to analysis can help reduce these artifacts.  

  

  

  

    ·        While the majority of the antibodies in the panel were raised in mouse, some of the antibodies were raised in rat; these are located on Plate 3   

  

            in wells F1-F12, G1 and G1-G4 (red wells on map of Plate 3). Ensure that anti-rat Ig secondary antibody is used with cells stained with these  

  

            antibodies.  

  

  

  

    ·        We recommend evaluating background staining on the cells by titrating the Alexa Fluor®  647 secondary antibodies before attempting a full  

  

             screen. Excess secondary antibody has been provided. Based on the cell types tested, we recommend using the anti-Mouse and anti-Rat  

  

             secondary antibodies at 1.25µg/ml (100µl per well).  

  

  

  

    ·        We recommend the following negative controls: (1) unstained cells, (2) cells + anti-mouse secondary antibody and   

  

            (3) cells + anti-rat secondary antibody. Blank wells (labeled as "buffer" on the plate maps) are provided for this purpose.   

  

  

  

    ·        For flow cytometric analysis we recommend running 500,000 to 1,000,000 cells per well for best results. However, we have been successful   

  

            in running as few as 250,000 cells per well.  

  

  

  

    ·         For flow cytometric analysis we recommend using a 96-well HTS plate loader. However, we have also been successful transferring stained         cells from 96-well plates into BD Falcon™ 12 X 75 mm round bottom tubes (Cat. No. 352008) and using a manual loader to run samples.  

  

  

  

    Reconstituting the antibody:  

  

  

  

    ·        After removing BD Lyoplate Human Cell Surface Marker Screening Panel plates from foil bags, centrifuge at 300 X g for 5 minutes.  

  

  

  

    ·        Hold the plate firmly on the work bench and gently remove the foil seal starting from one end and pulling across the plate to completely         remove the seal. Once the foil seal is removed, all lyophilized antibodies must be immediately reconstituted. Do not replace the lid on the         plate prior to reconstitution.   

  

  

  

    ·        Using a multi-channel pipette, reconstitute lyophilized antibodies in 110 µl of 1X sterile PBS. This results in an antibody solution that   

  

            contains five tests (20 µl/test). Be sure to use fresh pipette tips for each row to prevent well-to-well contamination. Allow antibodies to         reconstitute for five minutes at room temperature.   

  

  

  

    ·        Store the reconstituted antibodies at 4°C  until the cells are prepared for experiments. Reconstituted antibodies can be stored   

  

            in plates with lids at 4°C  for at least 10 days. Seal the plate edges (with lid on) with Parafilm "M"®  laboratory film to prevent loss  

  

            of reconstituted antibody due to evaporation.  

  

  

  

    Screening cells by flow cytometry:  

  

  

  

    1.        Prepare a single cell suspension of live cells from a cell line, tissue or a three dimensional culture. For adherent cell lines, we recommend   

  

            using either a mild enzyme such as Accutase™ or a non-enzymatic dissociation buffer.  

  

  

  

    2.        Wash the cells in two to four volumes of 1X PBS. Centrifuge at 300 X g for 5 minutes.  

  

  

  

    3.        Remove any clumps by passing the cells through a BD Falcon™ 40 or 70 µm cell strainer (Cat. No. 352340, Cat. No. 352350).  

  

  

  

    4.        Determine the cell concentration and total number of cells. If you are dissociating tissue or a three dimensional culture, we recommend   

  

            treating the single cells with DNase to prevent cell clumping. Resuspend cells in the recommended growth media or 1X PBS with calcium   

  

            and magnesium with the addition of 100 units/ml DNase at 10 million cells per ml. Incubate for 15 minutes at room temperature.  

  

  

  

    5.        Wash the cells in two to four volumes of 1X PBS. Centrifuge at 300 X g for 5 minutes.  

  

  

  

    6.        Prepare 275 ml of BD Pharmingen Stain Buffer (FBS) with the addition of 5 mM EDTA (final concentration) for subsequent steps.  

  

  

  

    7.        Resuspend the sample in BD Pharmingen Stain Buffer + EDTA. You will need 135 to 270 million cells (in approximately 27 ml total         volume) to fill the antibody containing wells of the three plates (500,000-1,00,000 cells per well). The minimum number of cells per well   

  

            will depend on the cytometer and/or loss of cells during washing. We have been successful in running as few as 250,000 cells per well.  

  

  

  

    8.        Label three BD Falcon™ round bottom 96 well plates (Cat No. 353910) plates 1, 2 and 3 for your sample plates.  

  

  

  

    9.        Using a multi-channel pipette aliquot 100 µl of cell solution to required wells of the three labeled round-bottom 96-well plates.  

  

  

  

            a.        If you have a limited number of cells, you can omit buffer only wells from plate 3. Please refer to the Plate 3 map to identify   

  

                    wells that can be excluded taking into consideration unstained cells and secondary antibody controls.  

  

  

  

    10.        Using a multi-channel pipette, pipette up and down 2-3 times to fully mix the reconstituted antibody from the first row of wells from the BD         Lyoplate Screening Panel Plate 1. Add 20 µl to the cells in the corresponding wells of sample plate 1. Continue to add reconstituted   

  

            antibody to the corresponding sample wells for all remaining wells of each plate. Use fresh tips for every well. Incubate on ice for 20-30         minutes  

  

  

  

    11.        To wash, add 100 µl of BD Pharmingen Stain Buffer + EDTA to each well. Centrifuge at 300 X g for 5 minutes.  

  

  

  

    12.        Remove supernatant carefully and wash cells with an additional 200 µl of BD Pharmingen Stain Buffer + EDTA. Centrifuge at 300 X g   

  

            for 5 minutes.  

  

  

  

    13.        During the centrifugation step of the final wash, dilute the secondary antibody 1:200 dilution (1.25 µg/ml) in BD Pharmingen Stain Buffer   

  

            + EDTA. You will need about 26 ml of dilute anti-mouse secondary antibody and about 3 ml of diluted anti-rat secondary antibody.  

  

  

  

    14.        Remove supernatant and apply 100 µl of the appropriate secondary antibody directly to cells in each well and incubate for 20-30 minutes on         ice in the dark.  

  

  

  

            a.        Add anti-mouse secondary antibody to all wells of the first two labeled round-bottom 96-well sample plates. For sample plate 3, please                 refer to the Plate maps and add anti-mouse secondary antibody to the appropriate sample wells (white wells: all wells in rows A, B and                 C; wells D1-D5 and E1-E5) and add anti-rat secondary antibody to the appropriate wells (red wells: wells F1-F12 and G1-G4).  

  

  

  

            b.        Use remaining wells in sample plate 3 that do not contain antibody (gray wells) to set up unstained cells and anti-rat secondary                                 antibody        controls.  

  

  

  

    15.        To wash, add 100 µl of BD Pharmingen Stain Buffer + EDTA to each well. Centrifuge at 300 X g for 5 minutes.  

  

  

  

    16.        Remove supernatant and wash cells with an additional 200µl of BD Pharmingen Stain Buffer + EDTA. Centrifuge at 300 x g for 5   

  

            minutes.  

  

  

  

    17.        At this point you may wish to fix your cells prior to analysis. To fix, remove supernatant and add 100 µl of 4% paraformaldehyde in 1X PBS         or BD Cytofix™ Fixation Buffer (Cat. No. 554655) per well and incubate for 10 minutes. If you do not wish to fix your cells go to step 19.  

  

  

  

    18.        Wash cells twice with 1X PBS. Centrifuge at 300 X g for 5 minutes.  

  

  

  

    19.        Remove supernatant and resuspend cells in 150 µl of BD Pharmingen Stain Buffer + EDTA per well. Analyze your samples on a flow         cytometer. We recommend collecting at least 10,000 events per well. While the first plate is being read, store the other plates on ice in the         dark.  

  

  

  

    20.        Analysis templates are available at bdbiosciences.com/resources/stemcell under Tools.  

  

  

  

    Screening cells by bioimaging:  

  

  

  

    1.        Seed the cells in appropriate culture medium at an appropriate cell density in a BD Falcon™ 96-well Imaging Plate (Cat. No. 353219), and         culture cells to an appropriate density. We recommend 70-80% confluency for imaging screens.  

  

  

  

    2.        BD Lyoplate surface staining should be performed on live cells as fixation can cause artifacts (false positive and negative signals) with   

  

            some cell surface markers. In cases where cells must be fixed prior to staining, we recommend confirming any positive hits with a live   

  

            sample stain using imaging or flow cytometry.  

  

  

  

    3.        Using a multi-channel pipette add 20 µl of each reconstituted antibody to the correspnding wells of your sample plates and incubate on ice   

  

            for 20-30 minutes. Stain cells directly in 50 to 100 µl of fresh growth media. If staining fixed cells, stain cells in 1X PBS.  

  

  

  

    4.        Wash cells twice in 100 µl 1X PBS.  

  

  

  

    5.        Dilute secondary antibodies to 1:100 (2.5 µg/mL) in growth media and apply 100 µl of the appropriate secondary antibody directly to cells   

  

            in each well of the sample plates and incubate for 20-30 minutes on ice in the dark. You will need about 26 ml of diluted anti-mouse   

  

            secondary antibody and about 3 ml of diluted anti-rat secondary antibody.  

  

  

  

            a.        Add anti-mouse secondary antibody to all wells of the first two labeled imaging 96-well sample plates. For sample plate 3, please  

  

                    refer to the Plate maps and add anti-mouse secondary antibody to the appropriate sample wells (white wells: all wells in rows A, B and                 C; wells D1-D5 and E1-E5) and add anti-rat secondary antibody to the appropriate wells (red wells: wells F1-F12 and G1-G4).  

  

  

  

            b.        Use remaining wells in sample plate 3 that do not contain antibody (grey wells) to set up unstained cells and anti-rat secondary                                 antibody controls.  

  

  

  

    6.        Remove supernatant and wash cells twice in 100 µl 1X PBS.  

  

  

  

    7.        At this point you may wish to fix your cells prior to analysis. To fix, remove supernatant and add 100 µl of 4% paraformaldehyde in 1X PBS         or BD Cytofix Fixation Buffer per well and incubate for 10 minutes. If you do not wish to fix your cells go to step 9.  

  

  

  

    8.        Remove the fixative from the wells, and wash the wells twice with 100 µl of 1X PBS.  

  

  

  

    9.        Add 100 µl 1X PBS with a cell-permeable nucleic acid stain, such as Hoechst 33342 Solution (Cat. No. 561908).  

  

  

  

    10.        Analyze your samples on a high content bioimager.
