| 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 | DMEM, 10% FBS, 100 μg/ml Zeocin (Cat. No. R250-01, Life Technologies) |
| Complete Growth Medium | DMEM (Cat. No. 10566, Life Technologies), 10% FBS |

Figure 1. Angiotensin II-induced concentration-dependent stimulation of intracellular calcium mobilization in HEK293T/AT1 cells. The cells were loaded with Calcium-4 (Cat. No. R8142; Molecular Devices) prior to being stimulated with agonist angiotensin II. 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 angiotensin II (Mean ± SEM, n = 3). The EC50 of angiotensin II on this cell was 3.45 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. »
