CHO-K1/BB1 Stable Cell Line

Figure 1: Neuromedin B-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/BB1 cells. The cells were loaded with Calcium-4 (Cat. No. R8142, Molecular Devices) prior to stimulation with a BB1 receptor agonist, Neuromedin B. The intracellular calcium change was measured by FLIPRTETRA. The relative fluorescent units (RFU) were normalized and plotted against the log of the cumulative doses (5-fold dilution) of Neuromedin B (Mean ± SEM, n = 3). The EC50 of Neuromedin B on this cell was 0.30 μM.

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.

CHO-K1/BB1 Stable Cell Line

Recombinant CHO-K1 cells stably overexpress human bombesin receptor subtype 1 (BB1), or neuromedin B receptor (NMBR), on the surface and contain high levels of G protein Gαq to couple with the receptor in downstream signaling pathways.
