Every lot is tried & tested in a relevant biological assay.

- Alomone Labs Resiniferatoxin induces Ca2+ influx via activation of TRPV1 expressed in HEK293 cells.Cells were loaded with 1mM fluo-3 AM and then stimulated with Resiniferatoxin (#R-400). The left panel shows the intracellular Ca2+ levels 10 sec post stimulation with different concentrations of Resiniferatoxin plotted against drug concentration (ED50 = 2 µM) . The right panel shows cytoplasmic Ca2+ before and after stimulation of cells with 10 µM Resiniferatoxin.
Resiniferatoxin is a potent and selective agonist of the TRPV1 (Vanilloid/Capsaicin receptor) channel.1 Application of sub-nanomolar concentrations of Resiniferatoxin irreversibly induces a sustained slow current and depolarization in DRG neurons.2
Treatment of rats with Resiniferatoxin, like treatment with capsaicin, causes hypothermia, neurogenic inflammation and pain. These responses were followed by a loss of thermoregulation, by desensitization to neurogenic inflammation and by chemical and thermal analgesia, with a cross-tolerance between Resiniferatoxin and capsaicin.1
