Cat.No.
HSP104-319Y
Species
Saccharomyces cerevisiae
Product Name
Recombinant Yeast Heat Shock Protein 104
Product Overview
Recombinant Saccharomyces cerevisiae HSP104 protein was overexpressed in E. coli and purified by conventional column chromatography techniques (908 aa, 102 kDa).
Description
Hsp104 is a molecular chaperone required for stress tolerance and for maintenance of [psi(+)] prions in the budding yeast Saccharomyces cerevisiae. Hsp104 can protect yeast cells against high temperature and high concentration of ethanol but mutation studies have shown this protein is not required for normal growth. Hsp104 was cloned into an E. coli expression vector and was purified to apparent homogeneity by using conventional column chromatography techniques.
