CD45 (CD45 Antigen, B220, GP180, Leukocyte Common Antigen, LCA, L-CA, LY5, LY-5, Protein Tyrosine Phosphatase Receptor Type C, Protein Tyrosine Phosphatase Receptor Type C Polypeptide, PTPRC, T200, T200 Glycoprotein) (PE)

CD45 or Leukocyte Common Antigen (LCA/T200) family is comprised of at least four isoforms (CD45RA, CD45RB, CD45RC, and CD45RO) of membrane glycoproteins with MW of 180kD-220kD. It consists of a large, heavily glycosylated, amino-terminal extracellular domain of 400-550 amino acids, a single transmembrane region and a large carboxy-terminal cytoplasmic domain of 700 amino acids. CD45/LCA is expressed on hematopoietic cell lines but absent on non-hematopoietic cell lines, normal and malignant non-hematopoietic tissues. The intracellular portion of CD45 proteins has phosphatase activity and is involved in regulation of transmembrane signals, functioning as a leukocyte membrane receptor capable of transducing signals via its phosphotyrosine phosphatase domains.||Applications:|Suitable for use in Flow Cytometry.
