CHO-K1/PAC1/Gα15 Stable Cell Line

Figure 1: PACAP-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/PAC1 cells. The cells were loaded with Calcium-4 prior to being stimulated with PAC1 receptor agonist, PACAP. The intracellular calcium change was measured by FLIPR. The relative fluorescent units (RFU) were normalized and plotted against the log of the cumulative doses (5-fold dilution) of PACAP (Mean ± SD, n = 2). The EC50 of PACAP on CHO-K1/PAC1 cells was 68.9 nM.
Note:
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 and starts at Bottom and goes to Top with a sigmoid shape.

CHO-K1/PAC1/Gα15 Stable Cell Line

The Vasoactive intestinal Peptide/Pituitary Adenylate Cyclase Activating Polypeptide (VPAC) receptor is G protein-coupled and has been divided into at least three types: PAC1, VPAC1, and VPAC2. High expression of PAC1 is observed in CNS and the adrenal medulla. Several splice variants of PAC1 result in proteins that differ at the N-terminus and third intracellular loop; these variants differ in their affinities for PACAP and abilities to activate Gq and Gs. This manual describes establishment of a cell line and a protocol of pharmacologically validated human PAC1 GPCR receptor (Genebank Accession Number: NM_003382).
