Abstract Object: to obtain large quantities of β2-adrenergic receptor (β2AR) and detect β2-agonist.Method:Mouseβ2AR cDNA gene was amplified by PCR, then linked with EGFP and inserted into yeast expression vector pPICZαA. The reconstructed plasmid , PICZαDNAsGFP was transformed into Pichia pastoris KM71. After induction, a recombinant protein about 75kD in size was determined by western blot. 125ICYP was used to determine the activity of recombinantβ2AR. These results showed that the expressed protein is active.
