Assay: HiBiT
DC50: > 30000 nM
Assay description: Parental Jurkat cells (ATCC, TIB-152) were grown in complete RPMI medium consisting of RPMI 1640 Medium (Gibco, 61870036) supplemented with 10% fetal bovine serum (Gibco, 10082147) and 1x Pen Strep (Gibco, 15140122). The sequence encoding the HiBiT tag (Promega) was integrated into the 5' end of the coding sequence on both alleles of the PTPN2 gene in Jurkat cells by CRISPR to create the Jurkat-PTPN2-N-HiBiT cell line. The sequence for the HiBiT tag was integrated into the 3' end of the coding sequence on both alleles of the PTPN1 gene in Jurkat cells by CRISPR to create the Jurkat-PTPN1-C-HiBiT cell line.
Degradation of HiBiT-tagged proteins was monitored by luminescence using the Nano-Glo HiBiT Lytic Detection System (Promega, N3040). Five thousand cells per well of either Jurkat-PTPN2-N-HiBit or Jurkat-PTPN1-C-HiBiT were plated into white opaque OptiPlate-384 microplates (Perkin-Elmer, 6007290) in 25 μL complete RPMI medium. Compounds were added to the cells using a Tecan D300e Digital Dispenser. Cells were incubated for 24 hours in a humidified incubator at 37°C and 5% CO2. Following the 24 hour incubation, Nano-Glo HiBiT Lytic Reagent was added to cells and luminescence levels were read on a CLARIOstar Microplate Reader (BMG LABTECH). Each plate included a vehicle control (0.1% DMSO) from which % degradation for test compounds was calculated. A four-parameter curve fit was used to determine DC50 and Dmax values.
