生物活性

Sarafotoxin S6d (STX-b) is a polypeptide toxin isolated from the venom of the Israeli sand boa constrictor. Sarafotoxin S6d induces multiple electrocardiogram (ECG) changes including myocardial ischemia and hyperkalemia. Sarafotoxin S6d induces strong extracellular calcium-dependent vasoconstriction in rat aorta and exhibits positive inotropic effects in rat atria. Sarafotoxin S6d can be used in the study of cardiovascular diseases[1].

体内研究
(In Vivo)

Sarafotoxin S6d (0.3、1.0、3.0 和 5.0 nmol/kg;静脉注射) 在 0.3-3.0 nmol/kg 时可产生恒定压力效应和短暂的脉压升高。然而,在 5.0 nmol/kg 时,Sarafotoxin S6d 可在最初升高后导致血压、心率和呼吸频率迅速下降,导致大多数小鼠在 10 分钟内死亡[1]
Sarafotoxin S6d (5.0 nmol/kg;静脉注射) 可显著提高 K+ 水平 159%。此外,血浆酶 (LDH、CPK)、IP 和葡萄糖水平也显著升高。LDH 增加 60%,CPK 增加 91%,IP 增加 137%,葡萄糖增加 80%[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
