mHuwentoxin-IV is a naturally modified Huwentoxin-IV (HY-P1220). mHuwentoxin-IV inhibits tetrodotoxin-sensitive (TTX-S) voltage-gated sodium channels of dorsal root ganglion neurons with an IC₅₀ of 54.16 nM. mHuwentoxin-IV inhibition of tetrodotoxin-sensitive sodium channels is not reversed by strong depolarization voltages.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
