Biolegend, 675402, Purified anti-Hsp90α/β Antibody, 100μg

Hsp90 is one of the most abundant molecular chaperones. It modulates the stability and transport of a diverse set of critical factors, which include regulatory, metabolic, organizational, and signaling proteins. There are two major isoforms: α and β. In humans, the Hsp90β isoform is constitutively expressed, whereas the Hsp90α isoform is expressed under stress conditions. The Hsp90 dimer acts in concert with other chaperones and is regulated by a number of co-chaperones/accessory proteins. The upregulation of Hsp90 is associated with tumor progression, the invasion and formation of metastases, and the development of drug resistance. Therefore, Hsp90 has emerged as an important target for cancer treatment.
