Immunofluorescent analysis of Heat Shock Protein 90 (HSP90, green) in HeLa cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature and blocked with 1% Blocker BSA (Product # 37525) for 15 minutes at room temperature. Cells were probed without (left panel) or with (right panel) an HSP90 monoclonal antibody (Product # MA3-010) at a dilution of 1:100 for at least 1 hour at room temperature, washed with PBS, and incubated with DyLight 488 goat anti-mouse IgG secondary antibody (Product # 35502) at a dilution of 1:400 for 30 minutes at room temperature. F-Actin (red) was stained with DyLight 554 Phalloidin (Product # 21834) and nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ArrayScan or a ToxInsight Instrument at 20X magnification.

MA3-010 detects heat shock protein 90 kDa (HSP90) from human, mouse, rat, and bovine tissues. This antibody does not detect chicken HSP90.
MA3-010 has been successfully used in Western blot, immunofluorescence, and immunohistochemistry (paraffin) procedures. By Western blot, this antibody detects a 90 kDa protein representing HSP90 from MCF7 cell extract. MA3-011 is more sensitive in Western blot procedures and should be used when maximum sensitivity is desired. MA3-010 does not immunoprecipitate HSP90 in any form (free or complexed).
The MA3-010 antigen is purified mouse HSP90.
Heat shock proteins (HSP) are proteins that are expressed in response to various biological stress, including heat. HSP90 is a 90 kDa protein that is induced under stress conditions, but is also one of the most abundant cellular proteins found under non-stress conditions. HSP90 has been found to be associated with a number of other intracellular proteins, including steroid receptors, actin, tubulin, and some kinases. It has been suggested that HSP90 is necessary to maintain structural integrity of at least some steroid receptors to allow for ligand binding during receptor activation.
