Miltenyi Biotec Identification and Enumeration of Hla-B7, B27+ Cells By Flow Cytometry; 30 Tests in 60 µL

Miltenyi Biotec Clone REA176 recognizes HLA B7 and B27 class I human leukocyte antigens (HLA). Expressed on the surface of most nucleated cells, class I molecules are heterodimeric molecules and consist of a type I integral membrane α heavy chain and soluble β2 microglobulin protein. The extracellular region of the heavy chain further consists of three domains, of which one comprises the peptide binding groove. Antigens binding to class I molecules are 8–10 amino acids long and play an important role in recognition of the virus infected and malignant cells by cytotoxic T lymphocytes (CTLs). In addition, class I molecules interact with NK cell receptors to modulate the activity of NK cells. HLA-B7 is a risk factor for cervical cancer, sarcoidosis, and early-onset spondylarthropathies. HLA-B27 is known for its strong association with inflammatory spondyloarthropathies. It has been also discovered as a protective factor against some severe viral infections. | Additional information: Clone REA176 displays negligible binding to Fc receptors. - MLTY (Additional S&H or Hazmat Fees May Apply)
