Article Snippet: BL21 (DE3) competent E. coli (NEB) were transformed with plasmids encoding rat Ric-8A amino-terminally tagged with Glutathione S-transferase and a tobacco etch virus (TEV) protease cleavage site (GST-TEV) and selected on LB agar containing carbenicillin (50 μg/mL). .. GST-TEV-Ric-8A cassette was produced by restriction digestion of pFastBac-1 vector harboring the corresponding gene using BamHI and SalI, and was subcloned into the T7 bacterial promoter vector, pET21a (Millipore).

Article Snippet: Vector was transformed into BL21 (DE3) competent E. coli (NEB). .. Cells were induced with 0.75 mM IPTG and incubated at 37°C for three hours.

Article Title: Functional assignment of multiple catabolic pathways for D-apiose
Article Snippet: The resultant plasmids were transformed into E. coli C2527 (DE3) (New England Biolab), which contained an additional pRIL (STRATAGEN) for optimal protein expression and used as pre-cultures grown 37°C overnight in 25 ml selenomethionine containing PSAM media . .. After 6 hours of growth, the temperature of the cultures was increased to 42°C, incubated for 30 min (heat-shock) to activate E. coli chaperon systems for optimal protein folding and then reduced to 22°C for overnight incubation.
