Product ID L8429 
Name GsAF-1 
Molecular formula C160H245N47O41S7
Description
A 29 amino-acids peptide with 3 disulfide bridges , synthetic, initially isolated from the venom of the Chilean rose tarantula Grammostola rosea, also known as Grammostola spatulata.
Biological activity

GsAF-I inhibits voltage-gated sodium channel isoforms: Nav1.1, Nav1.2, Nav1.3, Nav1.4, Nav1.6 and Nav1.7 with respective IC50 values of 0.4, 0.6, 1.3, 0.3, 1.2 and 0.04 µM. In addition, the toxin blocks the hERG1 isoform with an IC50 value of 4.8 µM. GsAF-I does not inhibit sodium channels Nav1.5/SCN5A, and potassium channels Kv1.1/KCNA1, Kv1.4/KCNA4, Kv11.2/KCNH6, Kv11.3/KCNH7 (IC50>200 µM).
