CD45 Monoclonal Antibody (HI30), Brilliant Ultra Violet™ 563, eBioscience™, Invitrogen™

Description

• The HI30 mAb reacts with all isoforms of human CD45, also known as Leukocyte Common Antigen (LCA)
• CD45 is expressed by all hematopoietic cells excluding circulating erythrocytes and platelets
• The cytoplasmic portion of CD45 has tyrosine phosphatase enzymatic activity and plays an important role in activation of lymphocytes
• Applications Reported: This HI30 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This HI30 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells
• This may be used at 5μL (0.125μg) per test Brilliant Ultra Violet 563 (BUV563) is a tandem dye that emits at 564 nm and is intended for use on cytometers equipped with an Ultraviolet (355 nm) laser
• Please make sure that your instrument is capable of detecting this fluorochrome
• When using two or more Super Bright, Brilliant Violet, Brilliant Ultra Violet, or other polymer dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (SB-4401-42) or Brilliant Stain Buffer (00-4409-75) to minimize any non-specific polymer interactions
• Light sensitivity: This tandem dye is sensitive to photo-induced oxidation
• Please protect this vial and stained samples from light
• Excitation: 350 nm; Emission: 564 nm; Laser: Ultraviolet Laser
• 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.
