Invitrogen™ CD45RO Monoclonal Antibody (UCHL1)

Mouse Monoclonal Antibody

Supplier:  Invitrogen™ MA119452

Catalog No. 01-676-187

Description

This antibody recognizes an extracellular epitope of CD45R0, a 180 kDa low molecular weight isoform of the leukocyte common antigen (LCA). The antigen is expressed on a subset of memory/activated T cells and on cortical thymocytes. Pretreatment note: MA1-19452 does not require protein digestion pretreatment of paraffin sections and does not require antigen retrieval using heat treatment prior to staining of paraffin sections. A suggested positive control for this product is tonsil tissue.

CD45RO (UCHL1, ubiquitin carboxyl terminal esterase L1) is the shortest isoform of a receptor-type protein tyrosine phosphatase, CD45 glycoprotein. CD45 is crucial in lymphocyte development and antigen signaling, serving as an important regulator of Src-family kinases, promotes cell survival by modulating integrin-mediated signal transduction pathway and is also involved in DNA fragmentation during apoptosis. CD45 isoforms differ in their extracellular domains, whereas they share identical transmembrane and cytoplasmic domains. 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. CD45RO is expressed on macrophages, CD8+ T cells, activated T cells and myeloma cells. Besides the role in immunoreceptor signaling, CD45 is important in promoting cell survival by modulating integrin-mediated signal transduction pathway and is also involved in DNA fragmentation during apoptosis.
