Cat#:RP-3240AT;Product Name:Recombinant E.coli Dnak Protein;Description:DnaK, originally identified for its DNA replication by bacteriophage lambda 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 (amino acids 1-638) was amplified by PCR and cloned into an E. coli expression vector. DnaK 1-638 was overproduced in E. coli and was purified to apparent homogeneity using our unique column chromatography techniques.;Source:E.coli;AA Sequence:1-638aa;Molecular Characterization:69kDa;Purity:Greater than 95% by SDS-PAGE;Formulation:Liquid Solution;Stability:Recombinant E.coli Dnak Protein was stable up to 1 year from date of receipt at -70℃;Concentration:1mg/mL;Storage Buffer:Recombinant E.coli Dnak protein was supplied in 25 mM Tris-HCl, pH7.5, 100 mM NaCl, 5mM DTT,10%Glycerol;Storage:Recombinant E.coli Dnak Protein can be stored at +4℃for 1-2 weeks. It is recommended that the recombinant protein be aliquoted for optimal storage at -20 or -70℃. Please avoid repeated freeze-thaw cycles.;Usage:For Lab Research Use Only;
