Sequence VGINVKCKHS RQCLKPCKDA GMRFGKCTNG KCHCTPK.
Specificity Voltage-gated channel (Kv1.3 and Kv1.1) blocker. ADWX-1 blocks Kv1.3 channels with IC50 of 019 nM, and inhibits Kv1.1 channels with IC50 of 0.65nM.
Characteristics Source: Mesobuthus Martensii (Buthus martensii).
Molecular formula: C169H281N57O46S7.
Disulfide bonds between Cys7-Cys27, Cys13-Cys32, and Cys17-Cys34.
Purity > 98 %
Background ADWX-1 inhibits Kv1.3 channels heterologously expressed in HEK-293 cells. Kv1.3 channel currentsbefore and after application of 10pM ADWX-1. Kv1.3 channel currents were elicited by depolarizing the voltage steps of 200 ms from the holding potential -80 mV to +50 mV.
Molecular Weight 4072
Application Notes 019-0.65nM
Restrictions For Research Use only
Format Lyophilized
Reconstitution Any aqueous buffer. Centrifuge all product preparations before use (10000 x g 5 min).
Concentration after reconstitution: Dissolving 50g in 1.228ml will provide a stock solution of 10M.
Handling Advice Soluble in Water.
