CHO-K1/ADRA1B Stable Cell Line

Figure 1. Epinephrine-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/ADRA1B cells. The cells were loaded with Calcium-4 prior to being stimulated with the agonist, Epinephrine. The intracellular calcium change was measured by FLIPRTETRA. The relative fluorescent units (RFU) were normalized and plotted against the log of the cumulative doses (10-fold dilution) of Epinephrine (Mean ± SD, n = 2). The EC50 of Epinephrine on this cell was 17.7 nM.
Notes:
1. EC50 value is calculated with four parameter logistic equation:
Y=Bottom + (Top-Bottom)/(1+10^((LogEC50-X)*HillSlope))
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/ADRA1B Stable Cell Line

The α1-adrenergic receptor (AR) family consists of three closely related gene products (α1A, α1B, and α1D). They mediate the actions of norepinephrine (NE) and epinephrine in sympathetically innervated tissues and brain. Α1-ARs belong to the G protein-coupled receptor family and consist of single polypeptide chains that are predicted to form seven transmembrane spanning domains. With similar pharmacological and signaling properties, α1-AR subtypes act through Gq/11 proteins to activate phospholipase C, increase inositol 1,4,5-trisphosphate production, and increase intracellular Ca2+. ADRA1B functions in diverse settings include vasoconstriction and myocardial contractility, neuronal dopaminergic responses, dendritic cell migration and inflammatory responses, as well as neuroendocrine regulation of fertility.
