Description

Mouse Monoclonal Antibody

The monoclonal antibody HM47 recognizes the cytoplasmic domain of CD79a, also known as mb-1. CD79a is a 47 kDa membrane glycoprotein that associates with CD79b to form the heterodimeric B cell receptor (BCR). This receptor is responsible for B cell signaling, resulting in activation, apoptosis or anergy. Expression of CD79a is found throughout development from the earliest pre-B cell to plasma cells. CD79 is expressed on B cell neoplasms and some non-B cell malignancies such as AML. Unlike other antibodies that can be masked in B cell neoplastic cells, HM47 is a reliable antibody for recognizing CD79a and, as such, is a good marker for B cells. Becauseseveral variants of CD79a exist, the exact location of the epitope may differ slightly. Nevertheless, in humans thie epitope is typically amino acids 208-222. The HM47 antibody reacts to human, mouse, rat, dog, primates (rhesus, chimpanzee, macaque and baboon) pig, guinea rabbit, pig, horse, cow and chicken. Applications Reported: This HM47 antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This HM47 antibody has been pre-titrated and tested by intracelμLlar staining and flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.06 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 b...

CD79a is a disulphide-linked heterodimer that includes B29 (CD79b) polypeptide. CD79a is a B lymphocyte antigen receptor with an antigen-specific surface component Ig (immunoglobulin) that associates with Ig-alpha and Ig-beta, necessary elements for the expression and function of the B-cell antigen receptor. CD79a first appears at pre-B cell stage and persists until the plasma cell stage where it is found as an intracellular component. CD79a is found in the majority of acute leukemias of precursor B cell type, in B cell lines, B cell lymphomas, and in some myelomas. It is not present in myeloid or T cell lines. Diseases associated with CD79a include Agammaglobulinemia 3 and Agammaglobulinemia, Non-Bruton type.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

Can the eFluor Organic fluorochromes be used for intracellular staining?

Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).
