The antibody was purified by affinity chromatography and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
CD179a, also known as VpreB, is an 18 kD member of the Ig superfamily, with an Ig V-like domain structure (that lacks the β strand of a typical V domain). CD179a associates with CD179b to form a surrogate light (SL) chain, which associates with the IgM heavy chain and the CD79a/CD79b heterodimer to form the pre-B cell receptor (PreBCR) complex. The function of CD179a/CD179b is still under investigation, though it has been reported that deficiency of CD179a and/or CD179b impairs the maturation of the B cell precursors beyond the pre-B cell stage.
