Multiparameter flow cytometric analysis of FcεR1α expression on Mouse splenic leucocytes. C57BL/6 mouse spleen cells were treated with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899) to lyse erythrocytes, washed and preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) [Cat. No. 553141/553142]. The cells were then stained with BD Horizon™ BV421 Hamster Anti-Mouse CD3e (Cat. No. 562600), BD Horizon™ BV421 Rat Anti-Mouse CD45R/B220 (Cat. No. 562922), FITC Rat Anti-Mouse CD49b (Cat. No. 561067) antibodies and with either Alexa Fluor™ 647 Hamster IgG1, κ Isotype Control (Cat. No. 563612; Left Plot) or Alexa Fluor™ 647 Hamster Anti-Mouse FcεR1α antibody (Cat. No. 567804; Right Plot) at 0.5 µg/test. DAPI (4',6-Diamidino-2-Phenylindole, Dihydrochloride) Solution (Cat. No. 564907) was added to cells right before analysis. The bivariate pseudocolor density plot showing the correlated expression of FcεR1α (or Ig Isotype control staining) versus CD49b was derived from CD3-negative B220-negative gated events with the forward and side light-scatter characteristics of viable (DAPI-negative) leucocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

Flow cytometric analysis of FcεR1α expression on MC/9 cells. Cells from the mouse MC/9 (Mast Cells, ATCC CRL-8306) cell line were stained with Alexa Fluor™ 647 Hamster IgG1, κ Isotype Control (Cat. No. 563612; dashed line histogram) or Alexa Fluor™ 647 Hamster Anti-Mouse Anti-FcεR1α antibody (Cat. No. 567804; solid line histogram) at 0.5 μg/test. DAPI (4',6-Diamidino-2-Phenylindole, Dihydrochloride) Solution (Cat. No. 564907) was added to cells right before analysis. The fluorescence histogram showing FcεR1α expression (or Ig Isotype control staining) was derived from gated events with the light-scatter characteristics of viable (DAPI-negative) cells.

推奨アッセイ手順

BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
Since applications vary, each investigator should titrate the reagent to obtain optimal results.
An isotype control should be used at the same concentration as the antibody of interest.

MAR-1

The MAR-1 monoclonal antibody specifically recognizes Fc-epsilon RI-alpha (FceR1 alpha, also known as FcεR1α or FcER1a) which is likewise known as the IgE Fc receptor subunit alpha. FcεR1α is a type I transmembrane glycoprotein that is encoded by Fcer1a (Fc receptor, IgE, high affinity I, alpha polypeptide) which belongs to the Ig gene superfamily. As a single IgE-binding alpha subunit, FcεR1α complexes with signal transducing subunits including one beta subunit (FcεRIβ encoded by Ms4a2) and two disulfide-linked gamma subunits (FcεRIγ encoded by Fcer1g) to form the high-affinity receptor for IgE, Fc epsilon RI (FcεR1 or FcER1). FcεR1 is expressed on basophils and mast cells. Binding of cognate antigens (allergens) to FcεR1 with bound IgE antibodies leads to cellular activation and the release of mediators, including histamine and cytokines, that are responsible for allergic reactions. Tang et al. (2019) have reported that the MAR-1 antibody crossreacts with two other mouse Fc receptor chains, FcγRI (CD64) and FcγRIV (CD16-2), that are expressed by monocytes, macrophages, dendritic cells, or neutrophils. They suggested MAR-1 binding is specific for FcεRIa only on mast cells and basophils and that for other cell types reactive with the MAR-1 antibody, it may be appropriate to refer to these as MAR-1-positive (MAR-1+) cells.

Alexa Fluor™ 647

Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor™ 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 670-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
