GrTx1

GrTx1 is a peptide toxin originally isolated from the venom of the spider Grammostola rosea. GrTx1 blocks sodium channel, with IC₅₀s of 0.63 μM, 0.23 μM, 0.77 μM, 1.29 μM, 0.63 μM and 0.37 μM for Nav1.1, Nav1.2, Nav1.3, Nav1.4, Nav1.6 and Nav1.7, repectively. GrTx1 can be used for neurological disease research.

For research use only. We do not sell to patients.

Description

GrTx1 is a peptide toxin originally isolated from the venom of the spider Grammostola rosea. GrTx1 blocks sodium channel, with IC₅₀s of 0.63 μM, 0.23 μM, 0.77 μM, 1.29 μM, 0.63 μM and 0.37 μM for Nav1.1, Nav1.2, Nav1.3, Nav1.4, Nav1.6 and Nav1.7, repectively^[2]. GrTx1 can be used for neurological disease research^[1].

All Sodium Channel Isoforms :

In Vitro

GrTx1 (0-100 μΜ, 3 min) blocks Na⁺ currents of neuroblastoma F-11 cells with an IC₅₀ of 2.8 μM^[1]. GrTx1 (10 μΜ, 3 min) blocks about 85% Na⁺ currents of neuroblastoma F-11 cells with no effects on common K⁺ channels, such as Kv1.1 and 1.4^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
