RY703 Rat Anti-Mouse CD4
RY703 Rat Anti-Mouse CD4
Multicolor flow cytometric analysis of CD4 expression on viable Mouse splenic leukocytes.  BALB/c Mouse splenocytes 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. 553142]. The cells were then stained with BD Horizon™ BUV395 Hamster Anti-Mouse CD3e antibody (Cat. No. 563565) and with either BD Horizon™ RY703 Rat IgG2a, κ Isotype Control (Cat. No. 571454; Left Plot) or BD Horizon™ RY703 Rat Anti-Mouse CD4 antibody (Cat. No. 571611/571617; Right Plot) at 0.25 µg/test. DAPI Solution (Cat. No. 564907) was added to cells right before analysis. The bivariate pseudocolor density plot showing the correlated expression of CD4 (or Ig Isotype control staining) versus CD3e was derived from gated events with the forward and side light-scatter characteristics of viable (DAPI-negative) splenic leukocytes. Flow cytometry and data analysis were performed using a BD FACSymphony™ A5 SE Cell Analyzer System and FlowJo™ Software. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage

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 unconjugated antibody and free dye were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Recommended Assay Procedures

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.

Product Notices

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. 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.
  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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  7. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
  8. 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.
  9. Tandem fluorochromes contain both an energy donor and an energy acceptor. Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from the donor may be observed. Additionally, multi-laser cytometers may directly excite both the donor and acceptor fluorochromes. Therefore, we recommend for every tandem conjugate, a matched individual single-stain control be acquired for generating a compensation or spectral unmixing matrix.

RM4-5

The RM4-5 monoclonal antibody specifically binds to the CD4 (L3T4) differentiation antigen expressed on most thymocytes, subpopulations of mature T lymphocytes (i.e., MHC class II-restricted T cells, including most T helper cells and immunosuppressive regulatory T cells), and a subset of NK-T cells. CD4 has also been reported to be detected on pluripotent hematopoietic stem cells, bone marrow myeloid and B-lymphocyte precursors, intrathymic lymphoid precursors, and a subset of splenic dendritic cells. CD4 has been reported to be expressed on the plasma membrane of mouse egg cells and is involved in adhesion of the egg to MHC class II-bearing sperm. CD4 is an antigen coreceptor on the T-cell surface which interacts with MHC class II molecules on antigen-presenting cells. It participates in T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase lck. Purified RM4-5 mAb has been reported to block the binding of FITC-conjugated anti-mouse CD4 clones GK1.5 and H129.19, but not the RM4-4 clone.

RY703
The BD Horizon RealYellow™ 703 (RY703) Dye is part of the BD® family of yellow-green dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 557-nm and an emission maximum (Em Max) at 703-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RY703 can be used on both spectral and conventional cytometers and is designed to be excited by the Yellow-Green laser (561-nm) with minimal excitation by the 488-nm Blue laser. For conventional instruments equipped with a Yellow-Green laser (561-nm), RY703 can be used as an alternative to PE-Cy5.5 and we recommend using an optical filter centered near 700-nm (eg, a 695/40-nm bandpass filter).
