Description: This VIM3b monoclonal antibody reacts with human CD97, a member of the epidermal growth factor (EGF)-TM7 family of cell surface receptors. Present on a variety of hematopoietic cells, CD97 is most highly expressed on granulocytes and monocytes. CD97 can also be detected on lymphocytes, with T and NK cells expressing higher levels than B cells. Moreover, CD97 expression on T lymphocytes can be induced by stimulation of CD3 and CD28. Studies have demonstrated that CD97 is involved in granulocyte trafficking and T cell activation. CD55, also known as Decay-accelerating factor (DAF), is the ligand of CD97.
Due to alternative splicing, CD97 exists as three isoforms with molecular weights of 74, 80, and 86 kDa. The VIM3b monoclonal antibody recognizes each form.
