The Von Hippel–Lindau tumor suppressor (VHL) Binding Assay Kit is a homogeneous assay which measures the binding of VHL to the high-affinity VHL fluorescent probe (BDY FL VH032) using Fluorescence Polarization (FP). In addition, the kit includes the VHL inhibitor VH298 for use as an inhibitor control. This assay takes advantage of the fluorescent substrate BDY FL VH032. Using this kit, only one step on a 96-well plate is required. The BDY FL VH032 is incubated with the VHL complex in the presence of a compound of interest to produce a change in fluorescent polarization. The FP signal is measured using a fluorescent microplate reader capable of measuring fluorescence polarization.
