            Immunohistochemical analysis of CD45R (B220) was performed using formalin-fixed paraffin-embedded human tonsil tissue sections. To expose the target protein, heat-induced epitope retrieval was performed on de-paraffinized sections using using eBioscience™ IHC Antigen Retrieval Solution - Low pH (10X) (Product # 00-4955-58) diluted to 1X solution in water in a microwave at 100 degree Celsius for 10 minutes. ...

            Product Specific Information

            Description: The RA3-6B2 monoclonal antibody reacts with exon A-restricted isoform of mouse CD45, a 220 kDa surface molecule. CD45R/B220 epitope is mainly expressed by the B cell lineage from early Pro-B to mature B cells. However, some activated T cells, lymphokine activated killer cells (LAK), NK cell progenitors in the bone marrow, and T cells of the lpr/lpr mutant mouse also express this antigen.

            Applications Reported: The RA3-6B2 antibody has been reported for use in flow cytometric analysis, immunoprecipitation, and immunohistochemical staining of frozen or formalin-fixed paraffin embedded tissue sections. RA3-6B2 has also been reported in functional studies of B cells. (Please use Functional Grade purified RA3-6B2, Product # 16-0452, in functional assays).

            Applications Tested: The RA3-6B2 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. The RA3-6B2 antibody has been tested by immunohistochemistry of formalin-fixed paraffin embedded mouse tissue using low and high pH antigen retrieval and can be used at less than or equal to 5 µg/mL. The RA3-6B2 antibody has been tested by immunohistochemistry of frozen mouse tissue and can be used at less than or equal to 5 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

            Purity: Greater than 90%, as determined by SDS-PAGE.

            Aggregation: Less than 10%, as determined by HPLC.

            Filtration: 0.2 µm post-manufacturing filtered.

            Target Information

            CD45R (PTPRC) is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. CD45 contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains. CD45 is specifically expressed in hematopoietic cells and has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. CD45 glycoprotein is crucial in lymphocyte development and antigen signaling, serving as an important regulator of Src-family kinases. CD45 protein exists in multiple isoforms as a result of alternative splicing, and these isoforms differ in their extracellular domains, but share identical transmembrane and cytoplasmic domains. Further, these 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. In addition to its 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. CD45RA is an isoform of the CD45 complex and has restricted expression between different subtypes of lymphoid cells. Diseases associated with CD45 dysfunction include Severe Combined Immunodeficiency (T-cell negative, B-Cell Negative) and Hepatitis C.
