BTK assay

Bruton tyrosine kinase

Synonyms: ATK, PSCTK1, XLA, AGMX1, IMD1

Family: TK (tyrosine kinase)

BTK is non-receptor tyrosine kinase, which plays a crucial role in B-cell development. BTK is known to be expressed in many haematopoietic cell types and participate in B cells in multiple pathways1. Btk expression is assumed to be a prerequisite for B-cell proliferation and survival2. BTK inhibitor, ibrutinib, is used to treat B-cells cancers.

BTK 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.
