Immunogen Papain solubilised HLA-A2. Remarks: Spleen cells from immunised BALB/c mice were fused with cells of the mouse NS1 myeloma cell line.
Clone BB7-2
Isotype IgG2b
Specificity This antibody recognises the human HLA-A2 histocompatibility antigen. The epitope recognised by this antibody has been studied extensively and would appear to include the carboxy-terminus of the alpha-2 helix and a turn on one of the underlying beta strands. BB7.2 may be used for the Flow cytometric detection of HLA-A2 expression and has also been used for Immunoaffinity purification of HLA-A2 Molecules. Functionally the antibody is reported to inhibit MHC restricted cellular cytotoxicity.
Purification Affinity Chromatography on Protein G
Endotoxin Level Less than 0.01EU/μg
Alternative Name HLA Class I A-2 alpha / HLA-A2
Background Human leukocyte antigens are highly polymorphic proteins that are involved in the presentation of antigens to the T cell receptor. There are two classes of HLA antigens, class I (HLA A, HLA B and HLA C) and class II (HLA D).Synonyms: A-2 alpha chain, HLA class I histocompatibility antigen, HLAA2, MHC class I antigen A-2
Gene ID 100507703
NCBI Accession XP_003119274
UniProt P01892
Application Notes Flow cytometry (10 μg/mL): use 10 μL of of the suggested working dilution to label 10^6 cells or 100 μL whole blood. Immunoprecipitation. Functional assay (Inhibition of MHC resticted cytotoxicity): 5 - 10 μg/mL. Immunohistochemistry on frozen sections. Recommended positive control tissue: Tonsil.
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.
