生物活性

ShK toxin blocks voltage-dependent potassium channel (Kv1.3 channel). ShK toxin can be isolated from the whole body extract of the Caribbean sea anemone (Stichodactylu helianthus). ShK toxin competes with dendrotoxin I and α-dendrotoxin for binding to synaptosomal membranes of rat brain, facilitates acetylcholine release. ShK toxin suppresses K+ currents in cultured rat dorsal root ganglion neurons. ShK toxin also inhibits T lymphocyte proliferation[1][2].

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.
