Introduction

BLNK is a cytoplasmic linker or adaptor protein which has a significant role in B cell development. B-cell linker (BLNK) is essential for normal B-cell development. BLNK bridges B cell receptor-associated kinase activation with downstream signaling pathways, thus affecting different biological functions. BLNK associates with the effector proteins GRB2, Vav, NCK and PLC-g following activation of the B cell receptor. BLNK is phosphorylated by the Syk tyrosine kinase, which in turn permits activation of downstream effector proteins including GRB2 and PLC-g. Mutations in the BLNK gene cause hypoglobulinemia and absent B cells, a disease in which the pro- to pre-B-cell transition is developmentally blocked. Deficiency in the BLNK protein is seen in some cases of pre-B acute lymphoblastic leukemia.

Description

BLNK Human Recombinant fused with a 20 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 476 amino acids (1-456 a.a.) and having a molecular mass of 52.6kDa (Molecular weight on SDS-PAGE will appear higher). The BLNK is purified by proprietary chromatographic techniques.

Source

Escherichia Coli.

Physical Appearance

Sterile Filtered colorless solution.

Formulation

The BLNK solution (1 mg/ml) contains 20mM Tris-HCl buffer (pH8.0), 20% glycerol, 0.1M NaCl, 1mM DTT and 0.1mM PMSF.

Stability

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. 
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

Purity

Greater than 90.0% as determined by SDS-PAGE.
