Armenian Hamster monoclonal [HM79] to CD79b (Phycoerythrin)
Phycoerythrin. Ex: 488nm, Em: 575nm
Recognizes an extracellular epitope of mouse CD79b (CD79 beta, Ig beta), a component of B cell receptor (BCR) complex. We have data to indicate that this antibody may not cross react with Human. However, this has not been conclusively tested and expression levels may vary in certain cell lines/tissues.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Flow Cyt: Use at a concentration of 1 µg/ml.
ICC: Use at an assay dependent dilution.
IP: Use at an assay dependent dilution.
WB: Use at an assay dependent dilution. Predicted molecular weight: 26 kDa.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
Required in cooperation with CD79A for initiation of the signal transduction cascade activated by the B-cell antigen receptor complex (BCR) which leads to internalization of the complex, trafficking to late endosomes and antigen presentation. Enhances phosphorylation of CD79A, possibly by recruiting kinases which phosphorylate CD79A or by recruiting proteins which bind to CD79A and protect it from dephosphorylation.
Involvement in disease
Defects in CD79B are the cause of agammaglobulinemia type 6 (AGM6) [MIM:612692]. It is a primary immunodeficiency characterized by profoundly low or absent serum antibodies and low or absent circulating B cells due to an early block of B-cell development. Affected individuals develop severe infections in the first years of life.
Phosphorylated on tyrosine upon B-cell activation.
Cell membrane. Following antigen binding, the BCR has been shown to translocate from detergent-soluble regions of the cell membrane to lipid rafts although signal transduction through the complex can also occur outside lipid rafts.
