Spider venoms present an expansive chemical space of disulfide-rich peptides that selectively modulate neuronal ion channels. Venom Supplies focuses on curation and stabilization of venom pools from Theraphosa, Phoneutria, and Heteroscodra species, emphasizing peptides with defined motifs such as inhibitor cystine knots (ICK) and linear cationic sequences. Post-collection processing includes solid-phase extraction to remove high-molecular-weight contaminants and parallel LC fractionation that preserves bioactivity.
Voltage-gated sodium and mechanosensitive channel insights
Our Phoneutria nigriventer venom exhibits abundant PnTx isoforms with high-affinity interactions against NaV1.7, NaV1.8, and NaV1.9 channels implicated in nociception. Complementary mechanosensitive channel modulators, including Piezo2-active peptides, offer investigative leverage for touch and proprioception pathways. Accompanying data highlight IC₅₀ values derived from dorsal root ganglion neuron assays, enabling cross-study comparisons.
TRP and ASIC modulation for sensory biology
Spider venom peptides targeting TRPA1 and acid-sensing ion channels (ASICs) unlock mechanistic views on neurogenic inflammation and respiratory reflexes. Venom Supplies supplies annotated electrophysiology traces, cytokine release profiles, and structural alignments that facilitate hypothesis generation for drug discovery teams. These assets integrate seamlessly with content featured in the Pain Research and Neuroscience application portals.
Ethical sourcing and documentation rigor
Source colonies operate under enriched habitat programs with independent welfare audits. Venoms are pooled, filtered at 0.22 μm, and flash frozen before lyophilization to retain labile peptides. COAs include microbial testing, MALDI-TOF-based peptide mass fingerprints, and optional circular dichroism spectra to confirm peptide folding. Safety data sheets recommend protective eyewear, double-gloving, and dedicated waste streams to mitigate dermal or inhalation exposure risks.
