GsAF-2 | Product ID | L8430-100UG |
| Name | GsAF-2 |
| Molecular formula | C176H261N47O45S7 |
| Description |
A 31 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-II (also termed Kappa-theraphotoxin-Gr2c, GsAF-2) was originally isolated from the venom of Grammostola rosea spider. GsAF-II peptide toxin has antinociceptive and antiarrhythmic effects in mammals. The peptide is reported to block the following voltage-gated sodium channels: Nav1.1, Nav1.2, Nav1.3, Nav1.4, Nav1.6 and Nav1.7 with IC50 values of, respectively, 5.7, 12, 24, 4, 6.6 and 1.3 µM. This peptide also blocks hERG1 with an IC50 value of 4.7 µM. |
