G-protein independent binding assays are preferred methods in assaying GPCR activation especially in primary screening. Utilizing high-expression GPCR stable cell lines, GenScript offers cell membrane preparations validated by receptor binding assays.
With large-scale cell culture capabilities, GenScript also offers custom membrane preparation services upon your specifications.
Fig A. 0.5 μg of membranes prepared from CHO-K1 cells stably expressing ADRB2 receptors were incubated with indicated concentrations of [3H]CGP-12177 in the absence (total binding) or presence of 1000-fold excess unlabeled ICI 118551 (nonspecific binding, NSB). Binding was terminated by rapid filtration. Specific binding was defined by subtracting NSB from total binding. Data were fit to one-site binding equation using a non-linear regression method.
Fig B. 0.5 μg of membranes prepared from 293 cells stably expressing 5-HT7 receptors were incubated with indicated concentrations of [3H]5-HT in the absence (total binding) or presence of 1000-fold excess unlabeled 5-HT (nonspecific binding, NSB). Binding was terminated by rapid filtration. Specific binding was defined by subtracting NSB from total binding. Data were fit to one-site binding equation using a non-linear regression method.
