BRK assay

Breast tumour kinase

Synonyms: PTK6

Family: TK (Tyrosine kinase)

BRK is intracellular protein kinase that is significantly overexpressed in a majority of breast tumors1. Brk is not expressed in the normal mammary gland, while in great tumour cells it promotes growth factor signaling and cell migration. Brk expression is also increased in a number of other epithelial tumors, including ovarian and colon cancer2.

BRK kinase assay is run on mobility shift microfluidics platform (Caliper), which provides best in industry quality of data. We routinely run services associated with this kinase including: screening, profiling, dose-response studies and kinetic measurements. Please contact us for more information.
