Alexa Fluor™ 488 Rat Anti-Mouse CD8b
Alexa Fluor™ 488 Rat Anti-Mouse CD8b

Multiparameter flow cytometric analysis of CD8b expression on mouse splenocytes. Mouse AKR splenic leucocytes were stained with BD Horizon™ BUV395 Hamster Anti-Mouse CD3e antibody (Cat. No. 536565) and with either Alexa Fluor™ 488 Rat IgG2b, κ Isotype Control (Cat. No. 557726; Left Plot) or Alexa Fluor™ 488 Rat Anti-Mouse CD8b antibody (Cat. No. 567663; Right Plot) at 0.5 µg/test. BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. A bivariate pseudocolor density plot showing the correlated expression of CD8b (or Ig Isotype control staining) versus CD3 was derived from gated events with the forward and side-light scatter characteristics of viable (7AA-D-negative) leucocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. 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.

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.

H35-17.2

The H35-17.2 monoclonal antibody specifically binds to both alloantigeneic forms of the β chain of the CD8 differentiation antigen (Ly-3 or Lyt- 3).  The CD8 α and α' chains (CD8a) form heterodimers with the CD8 β chain (CD8b, Ly-3, or Lyt-3) on the surface of most thymocytes.  A subpopulation of mature T lymphocytes (i.e., MHC class I-restricted T cells, including most T suppressor/cytotoxic cells) expresses almost exclusively the CD8 αβ heterodimer (the α' chain is absent).  Subsets of γδ TCR-bearing T cells, intestinal intraepithelial lymphocytes, and dendritic cells express CD8a without CD8b. It has been suggested that the expression of the CD8a/CD8b heterodimer is restricted to T lymphocytes which matured in the thymus or in an extrathymic environment that had been influenced by thymus- initiated neuroendocrine signals.  CD8 is an antigen coreceptor on the T-cell surface which interacts with MHC class I 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 (p56lck). The H35-17.2 mAb blocks T-cell-mediated cytolysis of allogeneic lymphoma cells.

Alexa Fluor™ 488
Alexa Fluor™ 488 Dye is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 517-nm. Alexa Fluor™ 488 is designed to be excited by the Blue laser (488 nm) and detected using an optical filter centered near 520-nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
