Alomone Labs 6'-Iodoresiniferatoxin induces Ca2+ influx via activation of TRPV1 expressed in HEK293 cells.Cells were loaded with 2 mM fluo-3 AM and then stimulated with 6’-Iodoresiniferatoxin (#I-805). The left panel shows the intracellular Ca2+ levels 10 sec post stimulation with different concentrations of 6’-Iodoresiniferatoxin (ED50 = 0.8 μM) and plotted against drug concentration. The right panel shows intracellular Ca2+ levels before and after stimulation of cells with 2.5 μM 6’- Iodoresiniferatoxin.

- 6’-Iodoresiniferatoxin is an agonist of the TRPV1 (Vanilloid/Capsaicin receptor) channel.1 It is an iodinated form of the potent agonist Resiniferatoxin (#R-400). It displayed high affinity binding (Ki=0.71 nM) for the human TRPV1 receptor and functioned as a partial agonist.1
