CD45RB Antibody (754-9458-94) in IHC (P)
Immunohistochemical analysis of CD45RB was performed on formalin-fixed paraffin-embedded human tonsil (high expression) and human kidney (low expression) tissues. To expose the target protein, HIER was performed on de-paraffinized sections using BOND Epitope Retrieval Solution 2 (pH 9) for 10 min, followed by a 5 min cool down, a 1 min wash with ddH2O, and then transferred to 1X PBS. Tissues were permeabili... View More

Product Specific Information
Description: The monoclonal antibody PD7/26 recognizes CD45RB, which is an isoform of the Leukocyte Common Antigen (LCA) also known as CD45. CD45RB is a protein tyrosine phosphatase receptor that is present on most hematopoietic cells and absent on non-hematopoietic cells. Expression of CD45RB is more restricted than CD45 and can only be found on T cell subsets, B, NK, and myeloid cells. Regulatory T cells (Tregs) have been show to express low levels of CD45RB, which may correlate with increased migration to sites of infection. In contrast, high CD45RB expression results in IL-2 and IFN gamma production instead of IL-4 in vitro.
Applications Reported: This PD7/26 antibody has been reported for use in flow cytometric analysis, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, microscopy, and immunocytochemistry.
Applications Tested: This PD7/26 antibody has been tested by immunohistochemistry of formalin-fixed paraffin embedded tissue using high pH antigen retrieval and can be used at 20 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Using conjugate solutions: Centrifuge the protein conjugate solution briefly in a microcentrifuge before use; add only the supernatant to the experiment. This step will help eliminate any protein aggregates that may have formed during storage, thereby reducing nonspecific background staining.
Target Information
CD45RB is 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, but 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. CD45RB is expressed in microglia and inflammatory cells. In addition to involvement in immunoreceptor signaling, CD45 is important in promoting cell survival by modulating integrin-mediated signal transduction pathway and is involved in DNA fragmentation during apoptosis. CD45 is expressed on cells of the human hematopoietic lineage with the exception of mature red cells.
