CHO-K1/PAR2/Gα15 Stable Cell Line

Figure 1. Trypsin-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/PAR2/Gα15 cells. The cells were loaded with Calcium-4 prior to being stimulated with agonist glucagon. 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 trypsin (Mean ± SEM, n = 3). The EC50 of trypsin on this cell was 4.42 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.

CHO-K1/PAR2/Gα15 Stable Cell Line

Recombinant CHO-K1 cells stably overexpress human protease-activated receptor 2 (PAR2) on the surface and contain high levels of G protein Gαq to couple with the receptor in downstream signaling pathways.

Gene Synonyms GPR11, F2RL1
Background Protease-activated receptors (PAR) are a subfamily of G-protein coupled, seven-transmembrane domain receptors, which are cleaved within the aminoterminal exodomain by certain serine proteases at a specific peptide bond. Trypsin and mast cell tryptase, and more recently, the activated coagulation factors VIIa and Xa, have been identified as serine proteases able to activate mammalian PAR-2. As already indicated, PAR-2 is believed to be involved in inflammation. This role for PAR-2 implies that elastase and cathepsin G would paradoxically display an anti-inflammatory property by disarming PAR-2.
