Product Information
| Description: | Margatoxin, an alpha-KTx scorpion toxin, is a high affinity inhibitor of Kv1.3 (Kd=11.7 pM). Margatoxin inhibits the Kv1.2 (Kd=6.4 pM) and Kv1.1 (Kd=4.2 nM). Margatoxin, a 39 amino-acid-long peptide, is isolated from the venom of the scorpion Centruroides margaritatus and widely used in ion channel research. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
