Assays & Kits

The HSP90β? (C-Terminal) TR-FRET assay kit is designed to measure the inhibition of HSP90α binding to its protein target PPID (also known as Cyclophilin D or Cyp40) in a homogeneous, 384 reaction format. This assay requires no time-consuming washing steps, making it especially suitable for high throughput screening applications. The assay procedure is straightforward and simple. A sample containing terbium-labeled donor, dye-labeled acceptor, HSP90β?, substrate, and an inhibitor is incubated for 2 hours. The protein-protein interaction is then assayed by measuring the TR-FRET between the PPID and HSP90β? using a fluorescence reader.

This assay kit is designed to measure the inhibition of the HSP90α binding to its protein target PPID (also known as Cyclophilin D) in a homogeneous, 96 reaction format. This assay requires no time-consuming washing steps, making it especially suitable for high throughput screening applications. The assay procedure is straightforward and simple. A sample containing terbium-labeled donor, dye-labeled acceptor, HSP90α, substrate, and an inhibitor is incubated for 2 hours. The protein-protein interaction is then assayed by measuring the TR-FRET between the PPID and HSP90α using a fluorescence reader.

The HSP90α Assay Kit is designed for identification of HSP90α inhibitors using fluorescence polarization. The assay is based on the competition of fluorescently labeled geldanamycin for binding to purified recombinant HSP90α. The key to the HSP90α Assay Kit is the fluorescently labeled geldanamycin. Using this kit, only one simple step on a microtiter plate is required for HSP90α reactions. The fluorescently labeled geldanamycin is incubated with a sample containing HSP90α enzyme to produce a change in fluorescent polarization. The FP signal is measured using a fluorescent microplate reader capable of measuring fluorescence polarization.

The HSP90β (C-terminal) Inhibitor Screening Assay Kit is designed to measure the inhibition of HSP90β binding to its protein target PPID (also known as Cyclophilin D). With this kit, only three simple steps on a microtiter plate are required. First, a sample containing HSP90β, PPID, and an inhibitor of choice is incubated for thirty minutes. Next, acceptor beads are added, then donor beads, followed by reading the Alpha-counts.
