The 2D1 monoclonal antibody binds to isoforms of human CD45, a 180-240-kDa type I membrane glycoprotein, also known as LCA (leukocyte common antigen). CD45 is the first and prototypic receptor-like protein tyrosine phosphatase that expresses on all human leukocytes1,2. It is absent on mature erythrocytes, platelets, and non-hematopoietic cells. The antibody was conjugated to a fluorophore and purified by affinity chromatography.
