PIK3CA (Q546K)/PIK3R1 NanoBRET Kinase Assay

PIK3CA (Q546K)/PIK3R1 NanoBRET Target Engagement Intracellular Kinase Assay for screening of compounds binding to the target.

Target Overview

Target

PIK3CA (Q546K)/PIK3R1

HGNC Symbol

PIK3CA (Q546K)/PIK3R1

Synonyms

MGC142161, MGC142163, p110-alpha, PI3K, PI3K-alpha

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-PIK3CA (Q546K) Fusion Vector and PIK3R1 Expression Vector were seeded into the wells of 384-well plates. The cells were pre-treated with the NanoBRET Tracer K-3 and then treated with reference compound PI-103 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 program based on a sigmoidal dose response equation.
