ICFC - Quality tested

Recommended Usage:

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 1.0 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

C57BL/6 splenocytes were surface stained

C57BL/6 splenocytes were surface stained with CD45R/B220 (clone RA3-6B2) PE and intracellularly stained with CD79a (Igα) (clone F11-172) APC.


Mouse CD79a (Ig α chain) is a 47 kD type I integral membrane protein, known as mb-1 or Ig α. It forms a heterodimer with CD79b (Ig β chain). The CD79a and CD79b heterodimers are associated with surface IgM to form the B-cell receptor (BCR) that is necessary for signal transduction via the BCR in mature B cells. CD79a may play a role in mediating the transport of IgM to the cell surface. Clone F11-172 antibody recognizes the 47 kD membrane glycoprotein present on B lymphocytes.

Other Names: Mb-1, Igα
Structure: A 47 kD membrane glycoprotein which associates with CD79b to form part of B-cell receptor complex.
Distribution: CD79a is expressed on B cells at various differentiation stages, from pre-B cell to plasma cells. It is expressed probably before expression of cytoplasmic µu chain.
Function: Mediating the transport of IgM to the cell surface.
Ligand Receptor: CD79a/CD79b heterodimers are associated with surface IgM to form B cell receptor complex (BCR) to recognize specific antigen.
