This antibody binds to the HLA-B7 antigen and does not cross-react with HLA-B27 or other related HLA antigens. It can be used to distinguish true HLA-B27 positives from false HLA-B27 positives (i.e. HLA-B7 positive) in the investigation of such diseases as ankylosing spondylitis and anterior uveitis.

背景
HLA B belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta 2 microglobulin). The heavy chain is anchored in the membrane. Class I molecules play a central role in the immune system by presenting peptides derived from the endoplasmic reticulum lumen. They are expressed in nearly all cells. The heavy chain is approximately 45 kDa. Hundreds of HLA B alleles have been described.Synonyms: B-7 alpha chain, HLA class I histocompatibility antigen, HLAB, MHC class I antigen B7
