Recombinant Human B29/CD79B Protein (RP01381)

Overview

Product name	Recombinant Human B29/CD79B Protein
Catalog No.	RP01381
Description	Recombinant Human B29/CD79B Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Ala29-Asp159) of human CD79b/B29 (Accession #NP_000617.1) fused with a hFc tag at the C-terminus.
Bio-Activity	Measured by its binding ability in a functional ELISA. Immobilized Human CD79B at 2 μg/mL (100 μL/well) can bind Anti-CD79B Humanized Antibody with a linear range of 0.781-1.771 ng/mL.
Purity	> 95% by SDS-PAGE.
Endotoxin	<0.1EU/μg
Formulation	Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
Species	Human
Calculated MW	41.16 kDa

B-cell antigen receptor complex-associated protein beta chain (CD79B) is also known as B-cell-specific glycoprotein B29, Ig-beta, Immunoglobulin-associated B29 protein, B29 and IGB, which is a single-pass type I membrane protein containing one Ig-like V-type ( immunoglobulin-like ) domain and one ITAM domain.CD79b is required in cooperation with CD79A for initiation of the signal transduction cascade activated by the B-cell antigen receptor complex (BCR).CD79b can enhance phosphorylation of CD79A, possibly by recruiting kinases which phosphorylate CD79A or by recruiting proteins which bind to CD79A and protect it from dephosphorylation. Defects in CD79b are the cause of agammaglobulinemia type 6 (AGM6) that is a primary immunodeficiency characterized by profoundly low or absent serum antibodies and low or absent circulating B cells due to an early block of B-cell development.

Usage guide

Storage	Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Reconstitution	Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
