Isotype

Mouse IgG2b

Specificity

The antibody BB7.2 recognizes an extracellular epitope at the C-terminus of alpha-2 helix and a turn on one of the underlying beta strands within the human HLA-A2 histocompatibility antigen.

Application

FC (QC tested)

Application details

Flow cytometry: The reagent is designed for analysis of human blood cells using 20 μl reagent / 100 μl of whole blood or 10⁶ cells in a suspension. The content of a vial (2 ml) is sufficient for 100 tests.

Reactivity

Human

Immunogen

HLA-A2 solubilised by papain

Preparation

Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.

Formulation

Stabilizing phosphate buffered saline (PBS), pH 7.4, 15 mM sodium azide

Storage and handling

Store at 2-8°C. Protect from prolonged exposure to light. Do not freeze.

Antigen description

HLA-A2 (44 kDa) is the most frequent HLA-A allele in human ethnic populations. HLA-A, together with HLA-B and HLA-C, represent human HLA class I major histocompatibility (MHC) antigens. These intrinsic membrane glycoproteins are expressed on nucleated cells and noncovalently associate with an invariant beta2 microglobulin. They carry foreign determinants important for immune recognition by cytotoxic T cells, thus important for anti-viral and anti-tumour defence.

Flow cytometry analysis (surface staining) of human peripheral blood cells using anti-HLA-A2 (BB7.2) PE.
