Tamapin
詳情介紹:
Sequence | AFCNLRRCEL SCRSLGLLGK CIGEECKCVP Y. |
Specificity | Tamapin blocks KCa2 channels, a highly potent blocker towards KCa2 channels. |
Characteristics |
Source: Mesobuthus tamulus (Eastern Indian scorpion). Molecular formula: C146H240N44O41S6. Disulfide bonds between Cys3-Cys21, Cys8-Cys26, and Cys12-Cys28. |
Purity | > 98 % |
Background | Tamapin inhibits SKCa3 channels heterologously expressed in HEK-293 cells. SKCa3 channel currents, before and after application of 100nM Tamapin. The SKCa currents were elicited by 1μM internal calcium and 200 ms voltage ramps from -140 to +40 mV at the holding potential of 0 mV. |
Molecular Weight | 3459 |
Application Notes | 10-100nM |
Comment |
K+ channel toxin -KTx 5.4 |
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 1.446 ml will provide a stock solution of 10 M. |
Handling Advice | Soluble in Water. |
