KV2 Channel Blocker Explorer Kit

A Screening Package of KV2 Channel Blockers Economically Priced

Cat #: EK-220
Size: 5 Vials
Form: Lyophilized

Guangxitoxin-1E Cat #: STG-200

Size: 0.1 mg MW: 3948.7 Da Purity: >98% (HPLC) Net peptide content: 100%
Origin
Synthetic peptide
Effective concentration
1-100 nM.
Activity
Guangxitoxin-1E is a gating modifier of KV2.1 (KCNB1, IC50 of 1 nM), KV2.2 (KCNB2, IC50 of 3 nM) and KV4.3 (KCND3, IC50 of 10-20 fold higher concentration) channels. In pancreatic β cells it enhances glucose-stimulated insulin secretion by broadening the cell action potential and enhancing calcium oscillations1,2. The physiological modulation of KV2.1 channels during glucose-induced insulin secretion is MgATP-mediated3.

ProTx-I Cat #: STP-400

Size: 50 µg MW: 3988 Da Purity: >98% (HPLC) Net peptide content: 100%
Origin
Synthetic peptide
Effective concentration
10-100 nM.
Activity
ProTx-I inhibits voltage-gated Ca2+ (CaV3.1), K+ (KV2.1), and all Na+ channels tested (NaV1.2, NaV1.5, NaV1.7 and NaV1.8). The toxin shifts the voltage-dependence of channel activation to more positive potentials.
Storage before reconstitution
Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks. For longer periods, it should be stored at -20°C.
Reconstitution
Any aqueous buffer. Centrifuge all product preparations before use (10000 x g 5 min).
Storage after reconstitution
Up to two weeks at 4°C or three months at -20°C.

Activity
Stromatoxin-1 is a potent inhibitor of voltage-gated K+ channels. It inhibits delayed KV2.1, KV2.1/9.3, KV2.2, and transient KV4.2 channels1,2.
Storage before reconstitution
Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks. For longer periods, it should be stored at -20°C.
Reconstitution
Any aqueous buffer. Centrifuge all products preparations before use (1000 X g 5 min).
