| Product Description | 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. |
| Culture Properties | Adherent. |
| Stability | Stable through more than 16 passages with no significant changes in assay performance or expression profile. |
| Size | Two vials of frozen cells (>1×106 per vial in 1 mL). |
| Storage | Store cells in liquid nitrogen immediately upon receipt. Thaw and recover cells within one year from the date received. |
| Culture Medium | Ham’s F-12K (Kaighn’s), 10% FBS, 200 μg/ml Zeocin (Cat. No. R250-01, Life Technologies), 100 μg/ml Hygromycin B (Cat. No. 10687010, Life Technologies) |
| Complete Growth Medium | Ham’s F-12K (Kaighn’s), 10% FBS. |
| Freeze Medium-DATA | 45% Ham’s F-12K (Kaighn’s) (Cat. No. 21127, Life Technologies), 45% FBS (Cat. No. 10099-141, Life Technologies), 10% DMSO (Cat. No. D2650, Sigma) |
Figure 1. Oxotremorine M-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/M2/Gα15 cells. The cells were loaded with Calcium-4 (Cat. No. R8142, Molecular Devices) prior to being stimulated with agonist oxotremorin M. The intracellular calcium change was normalized and measured by FLIPR. The relative fluorescent units (RFU) were normalized and plotted against the log of the cumulative doses of oxotremorin M (Mean ± SEM, n = 3). The EC50 of oxotremorin M on this cell was 62.38 nM.
Notes:
EC50 value is calculated with four parameter logistic equation:
Y=Bottom + (Top-Bottom) / (1+10^((LogEC50-X)*Hill Slope))
X is the logarithm of concentration. Y is the response
Y is ∆RFU and starts at Bottom and goes to Top with a sigmoid shape. »
