Flow cytometric analysis of HLA-A3 expression on Jurkat cells. Jurkat cells were stained with PE Mouse IgG2a, κ Isotype Control (dashed line histogram) or PE Mouse Anti-Human HLA-A3 antibody (solid line histogram) at 0.5 µg/test. The fluorescence histogram showing HLA-A3 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable cells. Flow cytometric analysis was performed using a BD LSRFortessa™ X-20 Flow Cytometer System. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage
Product Notices
- 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.
- 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.

The GAP.A3 monoclonal antibody specifically recognizes the polymorphic HLA class I histocompatibility antigen, A-3 alpha chain (HLA-A3). This ~44 kDa human major histocompatibility complex (MHC) class I molecule noncovalently associates with the ~12 kDa monomorphic β2 microglobulin. Two major subtypes are encoded by HLA-A3, HLA-A3.1 and HLA-A3.2. HLA-A3 gene expression is more commonly detected in individuals from Europe and southern India. HLA-A3 is expressed on nearly all nucleated cells of HLA-A3-positive individuals. HLA-A3 functions in the presentation of antigens to CD8-positive T cells which may lead to the generation of HLA-A3-restricted cytotoxic T cells and memory T cells. When complexed with certain antigens, HLA-A3 can also bind to killer cell immunoglobulin-like receptors (KIR), such as KIR3DL2, and might regulate NK cell function.
Note: Since HLA-A3 expression varies between human populations, clone GAP.A3 staining can be donor-dependent. Based on in-house testing and current literature, individuals of European or Southern Indian descent more frequently express HLA-A3 than those of Asian descent. Data may differ between donors due to geographical variations of HLA-A3 expression.
