CDK12+Cyclin K NanoBRET Kinase Assay

CDK12+Cyclin K NanoBRET Target Engagement Intracellular Kinase Assay for screening of compounds binding to the target.
Target Overview

Target

CDK12+Cyclin K

HGNC Symbol

CDK12/CCNK complex

Synonyms

CRKRS; CRK7

Cell Line

HEK293 human epithelial cell line from ATCC

Assay Properties

Assay Format

384-well plate format using Promega’s NanoBRET TE Intracellular Kinase Assay

Assay Protocol

HEK293 cells transiently co-expressing NanoLuc- CDK12 fusion vector and Cyclin K Vector were seeded into the wells of 384-well plates. The cells were pretreated with the NanoBRET Tracer K-12 and then treated with reference compound AT7519 for 1 hour. The BRET signal was measured on an Envision 2104 Multilabel Reader. IC50 value was calculated and IC50 curve was plotted using the GraphPad Prism 4 program based on a sigmoidal dose response equation.
