Mouse anti Human CD9 antibody, clone 72F6 recognizes the human CD9 cell surface antigen, also known as 5H9 antigen, MIC3, MRP-1, Tetraspanin-29 or p24. CD9 is a ~24-27 kDa multi-pass transmembrane glycoprotein, a member of the tetraspanin family, expressed by B cells, monocytes, platelets and by neurons and glial cells.

In melanoma and breast cancer CD9 antigen expression may be linked to a favourable prognosis (Si et al. 1993).
