Invitrogen™ CD45 Monoclonal Antibody (30-F11), PE-Texas Red

Rat Monoclonal Antibody

Supplier:  Invitrogen™ MCD4517

Catalog No. MCD4517

Description

The Rat anti-Mouse CD45 Monoclonal Antibody (mAb) recognizes all isoforms of the CD45 antigen. Applications reported for this antibody include flow cytometry, immunohistochemistry (zinc- and formalin-fixed, paraffin embedded), and immunohistochemistry (acetone-fixed, frozen). For this PE-Texas Red™ conjugate: excitation 488 nm/peak emission 616 (nm). If the reagent is being diluted, it is recommended that only the quantity to be used within one week be diluted. Cells should be analyzed within 18 hours of staining for best results. Avoid light exposure with fluorochrome-conjugated antibodies. Use dim light during handling, incubation with cells, and prior to analysis.

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 been shown to be an essential regulator of T- and B-cell antigen receptor signaling and suppresses JAK kinases to regulate cytokine receptor signaling. CD45 is also important in promoting cell survival by modulating integrin-mediated signal transduction pathway, DNA fragmentation during apoptosis and inhibition or upregulation of various immunological functions.
