Anti-CD79a [HM47] rAb

Tool Details

*FOR RESEARCH USE ONLY

• Name: Anti-CD79a [HM47] rAb
• Alternate name: B-cell antigen receptor complex-associated protein alpha chain; Ig-alpha; MB-1 membrane glycoprotein; Membrane-bound immunoglobulin-associated protein; Surface IgM-associated protein
• Clone: HM47
• Tool sub type: Primary antibody
• Class: Recombinant
• Conjugation: Unconjugated
• Reactivity: Bovine ; Chicken ; Horse ; Human ; Guinea Pig ; Mouse ; Opossum ; Pig ; Primate ; Rat ; Rabbit
• Host: Mouse
• Description: The B cell Antigen receptor constitutes a disulphide linked heterodimer, consisting of CD79a / mb1 and CD79b / B29 polypeptides, non covalently associated with membrane bound immunoglobulins on B cells. 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 B cell lymphomas, in B cell lines, the majority of acute leukemias of precursor B cell type and in some myelomas. The CD79a/b heterodimer interacts with at least one tyrosine kinase (Lyn). Induction of tyrosine kinase activity after antigen binding causes phosphorylation of the CD79a/b dimer, and also of other molecules, thereby initiating intracellular signaling. CD79a is widely used as an adjunct to CD20 for detecting normal and neoplastic B cells in tissues sections.
• Immunogen: Synthetic peptide of 14 amino acids representing amino acids 202-216 of the human mb-1 cDNA sequence
• Isotype: IgG1
