Recombinant CHO-K1 cells stably overexpress human cholinergic receptor muscarinic 2 (M2) on the surface and contain high levels of G protein Gαi to couple with the receptor in downstream signaling pathways.
Recombinant CHO-K1 cells stably overexpress human somatostatin receptor 5 (SST5) on the surface and contain high levels of G protein Gαi to couple with the receptor in downstream signaling pathways.
