产品编号：HSP-011
产品规格：20μg/100μg/1mg
产品规格：20μg/100μg/1mg
| Synonyms | HSP-70, HSP70, DnaK, Chaperone protein dnaK, Heat shock protein 70, Heat shock 70 kDa protein, groP, grpF, seg, b0014, JW0013. |
| 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. Dnak（residues 508-638） of the substrate binding domain is a-helical ａnd appears to act as a lid covering the substrate binding cleft. DnaK（amino acid 508-638） was purified to apparent homogeneity by using conventional column chromatography techniques. Additional amino acid （Met） is attached at N- terminus. |
| Description | Recombinant DnaK Lid Covering Substrate domain produced in E.Coli is a single, non-glycosylated polypeptide chain containing 132 amino acids ａnd having a molecular mass of 14.6 kDa. |
| Source | Escherichia Coli. |
| Physical Appearance | Sterile filtered colorless solution. |
| Formulation | The DnaK protein contains 25mM Tris-HCl, pH7.5, 100mM NaCl, 5mM DTT ａnd 10%Glycerol. |
| Stability | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Avoid multiple freeze-thaw cycles. |
| Purity | Greater than 95.0% as determined by（a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE. |
