Recombinant Human B Lymphoid Tyrosine Kinase, His-tagged

• Cat.No.: BLK-1345H
• Product Overview: Recombinant human BLK protein was expressed with N-terminal His-tag in High-Five cells using baculovirus expression system and purified by using conventional chromatography techniques. MW: 59.8 kDa.

Specification

• Description: BLK is a 55kDa tyrosine kinase with SH3, SH2, and catalytic domains that contain consensus sequences of the Src protein tyrosine kinase family. This protein is expressed specifically in the B cell lineage and plays a role in the signaltransduction pathway that is restricted to B lymphoid cells.
