at the time of upload there has been no data, please, contact us to obtain most recent information on species reactivity and cross reactivity
Specificity
The antibody BB7.2 recognizes an 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.
About
Monoclonals of this antigen are available in different clones. Each murine monoclonal anibody has his own affinity specific for the clone. Mouse monoclonal antibodies are purified protein A or G and can be conjugated to FITC for flow cytometry or FACS and can be of different isotypes.
Shipping and storage
Mouse Monoclonal Antibody against Human HLA-A2, Clone: BB7.2 is transported on blue ice/ice packs and should be stored at temperatures between 1 and 5 degrees Celsius. Do not freeze! Avoid exposing the product to direct light, especially the conjugated antibodies as most conjugates are very sentitive to light.
Background
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._x000D_
