|Application ||WB, IHC, IP|
|Reactivity||Human, Mouse, Rat|
|Calculated MW||83264 Da|
|Application & Usage||Western blotting (0.5-4 µg/ml), in immunoprecipitation (10-20 µg/ml) and Immunohistochemistry (frozen sections, 10-20 µg/ml). However, the optimal concentrations should be determined individually. The antibody recognizes Hsp90α and Hsp90β of human, mouse, and rat origins.|
|Other Names||Heat shock 90 kDa protein 1A/1B, Heat shock 90 kDa protein 1/2, HSP90-1/HSP90-2, HSPA1A, HSPA1, HSPA1B|
|Formulation||200 µg (0.5 mg/ml) affinity purified rabbit polyclonal antibody in phosphate-buffered saline (PBS) containing 30% glycerol, 0.5% BSA, and 0.01% thimerosal.|
|Handling||The antibody solution should be gently mixed before use.|
|Reconstitution & Storage||-20 °C|
|Precautions||HSP90 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Synonyms||HSP90B, HSPC2, HSPCB|
|Function||Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function.|
|Cellular Location||Cytoplasm. Melanosome. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV|

Heat shock proteins (HSPs) are ubiquitously expressed in all organisms. A major function of HSP90 and other HSPs is to act as molecular chaperones. HSP90 forms a complex with glucocorticoid receptor (GR), rendering the non ligand-bound receptor transcriptionally inactive. HSP 90 binds the GR as a heterocomplex composed of either HSP56 or cyclophilin-40, forming an aporeceptor complex. HSP90 also exists as a dimer with other proteins such as p60/sti1 and p23, forming an aporeceptor complex with estrogen and androgen receptors.
