CD79b Molecule, Immunoglobulin-Associated beta (CD79B) antibody (APC) Primary Antibody
- Flow Cytometry (FACS), Immunoprecipitation (IP), Western Blotting (WB)
- The mouse monoclonal antibody CB3-1 recognizes an extracellular epitope of CD79b (CD79 beta, Ig beta), an approximately 38 kDa component of B cell receptor (BCR) complex.
HLDA VI., WS Code CD79.1
- Cross-Reactivity (Details)

- CD79b (CD79B Antibody Abstract)
- CD79b (Ig beta, B29) forms disulfide-linked heterodimer with CD79a (Ig alpha, MB1). They both are transmembrane proteins with extended cytoplasmic domains containing immunoreceptor tyrosine activation motives (ITAMs), and together with cell surface immunoglobulin they constitute B-cell antigen-specific receptor (BCR). CD79a and b are the first components of BCR that are expressed developmentally. They appear on pro-B cells in association with the endoplasmic reticulum chaperone calnexin. Subsequently, in pre-B cells, CD79 heterodimer is associated with lambda5-VpreB surrogate immunoglobulin and later with antigen-specific surface immunoglobulins. CD79a/b complex interacts with Src-family tyrosine kinase Lyn, which phosphorylates its cytoplasmic ITAM motives to form docking sites for downstream signaling.
- Application Notes
- The reagent is designed for Flow Cytometry analysis of human blood cells using 10 μ,l reagent / 100 μ,l of whole blood or 106 cells in a suspension.The content of a vial (1 ml) is sufficient for 100 tests.
The purified antibody is conjugated with cross-linked Allophycocyanin (APC) under optimum conditions. The conjugate is purified by size-exclusion chromatography and adjusted for direct use. No reconstitution is necessary.
- For Research Use only
- The reagent is provided in stabilizing phosphate buffered saline (PBS) solution containing 15 mM sodium azide.
- Sodium azide
- Precaution of Use
- This product contains Sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.
- 4 °C
- Storage Comment
- Store in the dark at 2-8°C. Do not freeze. Avoid prolonged exposure to light. Do not use after expiration date stamped on vial label.
