Monoclonal Antibody to CD69 (Clone: ABM39A4)

CD69 is a type II transmembrane protein of the C-type lectin family and its gene is located within the natural killer gene complex. In healthy subjects, CD69 is not detected in peripheral blood lymphocytes, but is expressed on small subsets of T and B cells in peripheral lymphoid tissues. CD69 gene maps at human chromosome 12, and behaves as an early activation gene that contains responsive elements for the transcription factors NF-kappaB, ERG-1 and AP-1. This protein acts as a leukocyte activation marker, and is involved in the activation of different leukocyte subsets as well as in the pathogenesis of chronic inflammation.
