Assay Method Information

Assay Name:  Homogeneous Time Resolved Fluorescence (HTRF) Assay
Description:  Table 2: Binding to Bcl-2 proteins Bcl-2, and Bcl-XL was also assessed using an HTRF assay. Background: FAM-Bak/Bad binds to surface pocket of the Bcl-2 protein family. This binding can be monitored by HTRF signals between anti-GST-Tb and FAM-peptide using GST-tagged Bcl proteins. Assay conditions: Bcl-2: 4 nM Bcl-2, 100 nM FAM-Bak peptide, Bcl-XL: 3 nM Bcl-XL, 40 nM FAM-Bad peptide in 20 mM K Phosphate, pH 7.5, 50 mM NaCl, 1 mM EDTA, 0.005% Triton X-100 and 1% DMSO (final). Assay procedure: Compounds were tested in 10-dose IC50 mode, in singlicate, with 3-fold serial dilution starting at 10 μM or 1 μM. Compound stock solutions were added to protein solution using Acoustic technology.
