Cat.No.
DnaK-1257H
Species
Mycobacterium Tuberculosis
Product Name
Recombinant Myobacterium Tuberculosis Molecular Chaperone DnaK
Product Overview
Recombinant Mycobacterium Tuberculosis Dnak produced inE.Coliis a single, non-glycosylated polypeptide chain containing 625 amino acids and having a molecular mass of 66.7 kDa.
Description
DnaK, originally identified for its DNA replication by bacteriophage l in E. coli is the bacterial hsp70 chaperone. This protein is involved in the folding and assembly of newly synthesized polypeptide chains and in preventing the aggregation of stress-denatured proteins.
Source
E. coli
Form
The DnaK protein was lyophilized from a concentrated (1mg/ml) solution containing 10mM sodium phosphate buffer pH 7.4, 130mM sodium chloride and 2.5mM KCl.
Purity
Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Stability
Lyophilized DnaK although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution DnaK should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Synonyms
