Relevance

Required in cooperation with CD79A for initiation of the signal transduction cascade activated by the B-cell antigen receptor complex (BCR) which leads to internalization of the complex, trafficking to late endosomes and antigen presentation. Enhances phosphorylation of CD79A, possibly by recruiting kinases which phosphorylate CD79A or by recruiting proteins which bind to CD79A and protect it from dephosphorylation.

Endotoxin

Less than 1.0 EU/μg as determined by LAL method.

Purity

Greater than 90% as determined by SDS-PAGE.

Activity

Yes

Bioactivity

Measured by its binding ability in a functional ELISA. Immobilized Human CD79B at 2 μg/mL can bind Anti-CD79B recombinant antibody (CSB-RA004958MA2HU) . The EC50 is 3.214-3.642 ng/mL.

Form

Lyophilized powder

Buffer

Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Molecular Weight

16.7 kDa

Storage Conditions

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
