Reacts with the 45 kDa transmembrane cell surface Fas or Apo-1 antigen (designated CD95 at the Fifth HLDA Workshop) which is expressed on a variety of normal and neoplastic cells. The Fas/Apo-1 antigen is a polypeptide, which plays a role in the programmed sequence of events leading to cell death, termed apoptosis. The DX2 clone specifically reacts with murine L cells, murine L1210 leukemia cells and murine P815 mastocytoma cells transfected with human Fas cDNA but not with untransfected parental cell lines. Cross-linking with DX2 delivers an apoptotic signal indicating that DX2 recognizes a functional epitope of the CD95 antigen. This antibody is routinely tested by flow cytometric analysis. Other applications were tested during antibody development only or reported in the literature. Profile of peripheral blood lymphocytes analyzed on a FACScan
