Description
The Chaperone Plasmid Set consists of five different plasmids, each of which is designed to express multiple molecular chaperones that function as a "chaperone team" to enable protein folding. Co-expression of a target protein with one of these chaperone teams increases the recovery of soluble proteins. Each plasmid carries an origin of replication derived from pACYC and a Cmrgene, which allows use withE. coliexpression systems utilizing ColE1-type plasmids containing an ampicillin resistance gene as a marker. The chaperone genes are situated downstream of anaraBorPzt-1(tet) promoter. Therefore, expression of target proteins and chaperones can be induced individually if the target gene is placed under the control of other promoters (e.g.lac). These plasmids also contain the necessary regulator (araCortetr) for each promoter.
