Product Description

The Mouse anti-Human CD45 Monoclonal Antibody (mAb) recognizes the CD45 antigen1, which is expressed on all cells of hematopoietic origin with the exception of platelets and red blood cells and their immediate precursors. CD45 is considered to be a pan leukocyte marker. For this Pacific Blue™ conjugate - Excitation/Peak Emission (nm): 405/455 CD45 (LCA, leukocyte common antigen) is a receptor-type protein tyrosine phosphatase (PTP) ubiquitously expressed in all nucleated hematopoietic cells, comprising approximately 10% of all surface proteins in lymphocytes. CD45 is absent on non-hematopoietic cell lines, normal and malignant, non-hematopoietic tissues. CD45 glycoprotein is crucial in lymphocyte development and antigen signaling, serving as an important regulator of Src-family kinases. CD45 protein exists as multiple isoforms as a result of alternative splicing, differ in their extracellular domains but share identical transmembrane and cytoplasmic domains. CD45RA is an isoform of the CD45 complex and has restricted expression between different subtypes of lymphoid cells. CD45 isoforms differ in their ability to translocate into the glycosphingolipid-enriched membrane domains and their expression depends on cell type and physiological state of the cell. CD45 has
