Anti-HSP 90 Antibody

This rabbit polyclonal reagent from Antibodies.com targets the 90 kDa heat shock protein, a widely studied molecular chaperone that assists client-protein folding and stabilizes signaling kinases such as EGFR, HER2, Akt, and p53. Validated for Western blot of lysates from Human, Mouse, and Rat origin and for ELISA, the antibody is supplied as 50 µl of unconjugated antiserum that can be paired with HRP- or fluorophore-conjugated secondaries. HSP90 is frequently overexpressed in tumor cells and is a focus of inhibitor development in oncology research, making this reagent useful when characterizing chaperone dependence in cancer cell lines and as a reference alongside other stress-response proteins. Storage at -20 °C in working aliquots limits freeze-thaw damage and preserves binding activity for repeated immunoblotting experiments.
