GroE Mix is a supplement for the PUREfrex® series reconstituted coupled transcription/translation systems, designed to promote proper folding and solubility of proteins that require molecular chaperones for proper protein folding. GroE Mix comprises an optimized ratio of highly purified E.coli-derived GroEL (Hsp60) and GroES.
Chaperone Supplement
DnaK Mix comprises highly purified and ratio-optimized E. coli DnaK, DnaJ and GrpE. DnaK, known as Hsp70, has ATPase activity and is stimulated by co-chaperones DnaJ and GrpE. DnaJ facilitates DnaK ATPase activity and binds to hydrophobic regions of synthesized proteins. GrpE stimulates ADP/ATP exchange of DnaK. DnaK Mix works well with PUREfrex®series and DsbC Set.
Chaperone Supplement
GroE Mix comprises highly purified and ratio-optimized E. coli GroEL (known as Hsp60) and GroES (works in conjunction with GroEL).
