Examples might include carbon or other energy taxes, standardized fuel-efficiency standards for automobiles, etc. "Common and coordinated" or "harmonized" policies refer to those adopted jointly by Parties.
GFP expression of transfected cells was also analyzed to standardize transfection efficiency.
All assays were performed in triplicate, with the Renilla-luciferase control used to standardize transfection efficiency.
β-galactosidase activities were measured to standardize the efficiency of transfection.
The Renilla luciferase vector pRL-TK (Promega, Madison, Wisconsin, USA) was co-transfected to standardize transfection efficiency in each experiment.
The primers were standardized and the efficiency was tested before performing real-time PCR; primers with an efficiency above 90% were used in this study.
Moreover, the relative profit difference (RPD) was calculated as an efficiency standardized measure of profitability of farms (Boone 2008).
Other initiatives in the pact would further integrate the region's electricity grid, standardize energy-efficiency requirements for appliances and streamline the approval of clean-energy projects.
