Antigen description
CD45 (LCA, leukocyte common antigen) is a receptor-type protein tyrosine phosphatase ubiquitously expressed in all nucleated hematopoietic cells, comprising approximately 10% of all surface proteins in lymphocytes. 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; these isoforms differ in their extracellular domains, whereas they share identical transmembrane and cytoplasmic domains. These 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. 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.

Flow cytometry analysis (surface staining) of human peripheral blood cells with anti-human CD45 (MEM-28) biotin.
1B-222_WB_appl
Anti-Hu CD45 Biotin (clone MEM-28) works in WB application under non-reducing conditions.

Western blotting analysis was performed on whole cell extracts (RIPA lysis buffer) of Jurkat, Raji, HeLa, and HEK293T cell lines, mixed and heated (100°C, 5 min) with non-reducing SDS-loading buffer. Samples were resolved using 7% Tris-glycine SDS gel electrophoresis.

Nitrocellulose membrane blot was probed with biotinylated mouse IgG1 monoclonal antibody MEM-28 (1 µg/ml), followed by IRDye 800CW Streptavidin (green). Multiplex fluorescent Western blot detection was performed.

CD45 molecules were detected at ~180-250 kDa in Jurkat and Raji cell lines.
