CD45RA Antibody (754-0458-94) in IHC (P)
Immunohistochemical analysis of CD45RA was performed on FFPE human tonsil tissue. 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 permeabilized with 0.1% Triton X-100 in 1X PBS for 30 min, washed three times in 1X PBS and... View More

Product Specific Information
Description: The HI100 monoclonal antibody reacts with human CD45RA, a 220 kDa molecule expressed by subpopulations of CD4+ peripheral T lymphocytes, CD8+ peripheral T lymphocytes, and B cells. The CD45RA+ T cell populations are mainly naive/virgin allowing the use of HI100 mAb as a phenotypic marker to discriminate T cell subsets.
Applications Reported: This HI100 antibody has been reported for use in flow cytometric analysis and immunohistochemical staining of paraffin-embedded tissue.
Applications Tested: This HI100 antibody has been tested by immunohistochemical staining of human 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
CD45RA is an isoform of the CD45 complex and has restricted expression between different subtypes of lymphoid cells. 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 and these isoforms differ in their extracellular domains, however, 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. 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. CD45 is expressed on cells of the human hematopoietic lineage, with the exception of mature red cells and is not detected on differentiated cells of other tissues. It is likely that CD45 plays an important role in signal transduction, inhibition or upregulation of various immunological functions. Diseases associated with CD45 dysfunction include severe combined immunodeficiency and Hepatitis C.
