Bis-Q 是一种乙酰胆碱 (ACh) 激动剂，靶向鱼类 Xenomystus nigris 的电压钳制肌纤维。Bis-Q 有两种形式：顺式-Bis-Q（非激动剂）和反式-Bis-Q（激动剂）。光异构化将顺式-Bis-Q 转化为反式-Bis-Q，从而诱导激动剂诱导电流。反式-Bis-Q 和 ACh 激活的通道具有相似的电导率和开放时间。闪光会增加反式-Bis-Q 与顺式-Bis-Q 的比例，直到达到光平衡。进一步的闪光会暂时增加激动剂诱导电流，表明反式-Bis-Q 与脱敏受体结合。较高浓度的顺式-Bis-Q 会产生更大的激动剂诱导电流，并呈指数衰减。

生物活性

Bis-Q is an acetylcholine (ACh) agonist that targets voltage-clamped muscle fibers of the fish Xenomystus nigris. Bis-Q exists in two forms: cis-Bis-Q (non-agonist) and trans-Bis-Q (agonist). Photoisomerization converts cis-Bis-Q to trans-Bis-Q, which induces agonist-induced currents. Channels activated by trans-Bis-Q and ACh have similar conductances and open times. Flashes increase the ratio of trans-Bis-Q to cis-Bis-Q until light equilibrium is reached. Further flashes transiently increase agonist-induced currents, indicating binding of trans-Bis-Q to desensitized receptors. Higher concentrations of cis-Bis-Q produce larger agonist-induced currents that decay exponentially.[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.
