mouse Anti-CD79a (B lymphocyte-specific MB1 protein, B Cell antigen receptor complex-associated protein alpha chain, CD79a molecule immunoglobulin associated alpha, Ig-alpha, IGA, IgM-alpha, Immunoglobulin-associated alpha, Ly54, MB-1 membrane glycoprotein, Membrane-bound immunoglobulin-associated protein, Surface IgM-associated protein) (FITC) Monoclonal Antibody [Clone:JCB117, HM47/A9]

A disulphide-linked heterodimer, consisting of mb-1 (or CD79a) and B29 (or CD79b) polypeptides, is non-covalently associated with membrane-bound immunoglobulins on B cells. This complex of mb-1 and B29 polypeptides and immunoglobulin constitute the B cell Ag receptor. CD79a first appears at pre B cell stage, early in maturation, and persists until the plasma cell stage where it is found as an intracellular component. CD79a is found in the majority of acute leukemias of precursor B cell type, in B cell lines, B cell lymphomas, and in some myelomas. It is not present in myeloid or T cell lines. Anti-CD79a is generally used to complement anti-CD20 especially for mature B-cell lymphomas after treatment with Rituximab (anti-CD20). This antibody will stain many of the same lymphomas as anti-CD20, but also is more likely to stain B-lymphoblastic lymphoma/leukemia than is anti-CD20. Anti-CD79a also stains more cases of plasma cell myeloma and occasionally some types of endothelial cells as well.

Applications: 
Suitable for use in Immunofluorescence, Flow Cytometry, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Flow Cytometry: 0.5-1ug/million cells
Immunofluorescence: 0.5-1ug/ml
Western Blot: 0.5-1ug/ml
Immunoprecipitation: 0.5-1ug/500ug protein lysate
Immunohistochemistry: Frozen & Formalin-fixed: 0.5-1ug/ml for 30 minutes at RT
(Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes)
Optimal dilutions to be determined by the researcher.

Positive Control:
Daudi or Ramos cells. Germinal center B-cells in a lymph node or tonsil.

Storage and Stability:
Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer.
Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Note: Applications are based on unconjugated antibody.
