Rabbit Anti-Human CD79a/IGA Antibody


Protein Information

Accession Number:
  • P11912
Target Species:
  • Human

Antibody Specifications

ELISA (recommended work dilution= 1:160,000 (at least detecting 6.25ng/ml))
Immunogen was synthetic peptide derived from Human CD79alpha . This antibody was produced from a rabbit immunized with the immunogen. The IgG fraction was purified from rabbit serum by ammonium sulphate precipitation followed by Protein A/G affinity chromatography.
Supplied as lyophilized and purified antibody originally containing PBS, without Preservative Stabilizers, such as Sodium Azide. The final concentration is indicated on the shipping vial. The antibody is stable for at least years from the data of receipt when stored at -20°C to -70°C. Reconstituted antibody (recommended with H20 1 mg/ml) can also be aliquoted and stored frozen at -20°C to -70°C in a manual defrost freezer for months without detectable loss activity. Upon reconstitution, the antibody can also be stored over months at 4°C. Please avoid freeze-thaw cycles.


CD79 (Cluster of Differentiation 79) is a transmembrane protein that forms a complex with the B-cell receptor (BCR) and generates a signal following recognition of antigen by the BCR. CD79 is composed of two distinct chains called CD79A and CD79B (formerly known as Ig-alpha and Ig-beta); these form a heterodimer on the surface of a B cell stabilized by disulfide bonding. CD79alpha and CD79b are both members of the immunoglobulin superfamily. Human CD79alpha is encoded by the mb-1 gene that is located on chromosome 19, and CD79b is encoded by the B29 gene that located on chromosome 17.Both CD79 chains contain an immunoreceptor tyrosine-based activation motif (ITAM) in their intracellular tails that they use to propagate a signal in a B cell, in a similar manner to CD3 generated signal tranduction observed during T cell receptor activation on T cells.


The antibody can specifically bind to its immunogen, and did not show any cross reactivity with unrelated antigens in ELISA. The specificity for binding to recombinant protein, cellular protein and native antigen is not defined. Cross reactivity with mouse and rat CD79alpha has not yet been tested.


Keep it at 4°C if intended for use within a month. Store at -20°C if over months. Minimize freezing and thawing when use.
