HSP90α (N-terminal) Assay Kit

Catalog #: 50298
Size: 384 reactions

Hsp90α is a molecular chaperone with essential functions in maintaining transformation. Inhibition of Hsp90α function has been shown to play a role in tumorigenesis and disease progression.

The HSP90α (N-terminal) 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 that can then be measured using a fluorescence reader.
