rProTx-I
詳情介紹:
Sequence | ECRYWLGGCS AGQTCCKHLV CSRRHGWCVW DGTFS. |
Specificity | 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. |
Characteristics |
Source: Thrixopelma pruriens (Peruvian green velvet tarantula)1. Molecular formula: C171H245N53O47S6. Disulfide bonds between Cys2-Cys16, Cys9-Cys21, and Cys15-Cys28. |
Purity | > 98 % |
Molecular Weight | 3988 |
Application Notes | 10-100 nM |
Comment |
-theraphotoxin-Tp1a, -TRTX-Tp1a |
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 1.255ml will provide a stock solution of 10 M. |
Handling Advice | Soluble in Water. |
