Hainantoxin-III
Jingzhaotoxin-V is a peptide that inhibits potassium currents in Xenopus laevis oocytes with an IC50 value of 604.2 nM. Jingzhaotoxin-V also inhibits tetrodotoxin-resistant and tetrodotoxin-sensitive sodium currents in rat dorsal root ganglion neurons with IC50 values of 27.6 and 30.2 nM, respectively.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Primary Dorsal Root Ganglion Sensory Neuron Culture
Primary dorsal root ganglion sensory neuron culture isolates DRG neuronal somata from rodent or human ganglia, dissociates tissue enzymatically and mechanically, and maintains post-mitotic sensory neurons in vitro for readouts such as neurite outgrowth, immunocytochemical marker expression, calcium imaging, electrophysiology, RNA/protein analysis, or neuropeptide release assays. The method reflects peripheral sensory neuron biology because DRG neurons are primary sensory neurons whose cell bodies reside in dorsal root ganglia and whose cultured dissociated cells can retain neuronal morphology, sensory-neuron marker expression, and stimulus-responsive properties depending on the downstream assay.
