Expression and activity of CB2.
A, Western blot performed on E. coli membranes expressing CB2. Proteins were probed with rabbit polyclonal antibody against His5 tag.
B, activation rates of G protein on E. coli membrane expressing CB2. The receptor was activated by addition of 10 μM agonist CP-55,940 and the rates of activation of G protein analysed by measuring the accumulation of 35S-γ-GTP-Gαi1 complex as described previously.(5)
