Recombinant Myobacterium Tuberculosis DnaK (HSP70)Synonyms HSP-70, HSP70, DnaK, Chaperone protein dnaK, Heat shock protein 70, Heat shock 70 kDa protein, HSP70, 70 kDa antigen, ML2496.
Introduction 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.
Description Recombinant Mycobacterium Tuberculosis Dnak produced in E.Coli is a single, non-glycosylated polypeptide chain containing 625 amino acids and having a molecular mass of 66.7 kDa.
Recombinant Myobacterium Tuberculosis DnaK (HSP70)Source Escherichia Coli.
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation 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.
Solubility It is recommended to reconstitute the lyophilized DnaK in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Recombinant Myobacterium Tuberculosis DnaK (HSP70)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.
Purity Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
