Background Information

HSP90, encoded by HSP90AA1, is a constitutively and ubiquitously expressed molecular chaperone that is crucial for the stability and function of many proteins. HSP90 provides chaperoning activity for client proteins; many of them are members of oncogenic pathways, indicating its implication in tumor malignancy. HSP90 mainly resides in the cytosol, while it can also be released to the extracellular space. Secreted Hsp90 is a C-terminal truncated form. It has been reported that the level of plasma Hsp90 is positively correlated with tumor malignancy in clinical cancer patients, and can be a promising diagnostic marker for tumor malignancy in clinical application.

Ekaterini (Verified Customer) (02-16-2022)

The best antibody to use for loading control. Always clear and it is not affected by drug treatments.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: ALL cell lines

Xiaoping (Verified Customer) (10-22-2018)

This antibody works well in iPS, iMns or MEF. The signal is pretty strong which is better than the one we used before and the background is very low.
