Other Notes
Small volumes of Grammostola rosea Hanatoxin-1 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Inhibits Kv2.1/KCNB1 and Kv4.2/KCND2 voltage-gated potassium channels. Acts as a gating modifier by shifting channel openings to more depolarized voltages and acts via the occupancy of multiple binding sites on the channel. The toxin binding sites are situated on the S3-S4 extracellular linker of the channel. At least two hanatoxin molecules can occupy the Kv2.1/KCNB1 channel, and maybe more (three or four). Can also inhibit calcium channels (Cav2.1/CACNA1A). Needs to partition into the membrane in order to bind to the channel.
