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.

FAQs for CD45 Antibody (NB110-81718). (Showing 1 - 2 of 2 FAQ).
We are interested in CD45 antibodies that could react with dog, please let me know which products in your catalog you would recommend.
I would recommend one of these CD45 antibodies to you, as these have all been validated for use with dog/canine samples.
We would like to order a CD45 antibody to stain immune cells that were isolated from a ligated sciatic nerve of mice with double immunofluorescence (using PFA-fixed tissue on slides). Which of the following rat monoclonal CD45 antibodies would you recommend: 30-F11, IBL-3/16 or 5C16?
I would recommend clone 30-F11. As clone IBL-3/16 has not yet been validated for IHC-P application, we would not be able to guarantee its workability on PFA-fixed tissue. Although both other clones i.e. 30-F11 and 5C16, would be good for your samples, CD45 30-F11 # NB100-77417 is a well known clone that offers more flexibility around protocol because of availability of its conjugated forms. It would be advantageous to use a conjugated primary as you are planning for double-immunostaining procedure.
