      RB705 Rat Anti-Mouse T- and B-Cell Activation Antigen
      RB705 Rat Anti-Mouse T- and B-Cell Activation Antigen

      Flow cytometric analysis of T- and B-Cell Activation Antigen expression on activated Mouse splenic leukocytes.  Concanavalin A-stimulated (3 days) Mouse splenocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) [Cat. No. 553141/553142]. The cells were then stained with either BD Horizon™ RB705 Rat IgM, κ Isotype Control (Cat. No. 570266; dashed line histogram) or BD Horizon™ RB705 Rat Anti-Mouse T- and B-Cell Activation Antigen antibody (Cat. No. 570602/570690; solid line histogram) at 0.5 µg/test. DAPI Solution (Cat. No. 564907) was added to cells right before analysis. The fluorescence histogram showing T- and B-Cell Activation Antigen expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable (DAPI-negative) lymphoblasts. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ Software. Data shown on this Technical Data Sheet are not lot specific.

      The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

      推荐的实验流程

      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 cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

      1. When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
      2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      3. An isotype control should be used at the same concentration as the antibody of interest.
      4. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      5. 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.
      6. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
      7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      8. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).

      GL7

      The GL7 antibody specifically recognizes the T- and B- Cell Activation Antigen which is also known as, the GL7 antigen. The GL7 antigen is a 35-kDa cell-surface protein that is expressed on T and B lymphocytes activated in vitro, on bone marrow Pre-B-II cells, germinal-center B cells, and the subpopulation of thymocytes that coexpress high CD3e levels.  The GL7 antibody recognizes an epitope containing nonsulfated α2-6-sialyl-LacNAc. There is strain variability with respect to GL7 antigen distribution on thymocytes and Con A-activated spleen cells. GL7 antigen expression is found to be higher on BALB/c mouse leucocytes than on C57BL/6 mouse counterparts. The GL7 antibody reportedly may crossreact with epitopes on molecules expressed by certain rat and human leucocyte subsets.

      RB705
      The BD Horizon RealBlue™ 705 (RB705) Dye is part of the BD® family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 498-nm and an emission maximum (Em Max) at 707-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RB705 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with minimal excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB705 can be used as an alternative to PerCP-Cy5.5 or BB700 and we recommend using an optical filter centered near 710-nm (e.g., a 695/40 or 710/50-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PerCP-Cy5.5. RB705 is on average brighter than PerCP-Cy5.5 and BB700, and has minimal spillover into Yellow-Green detectors.
