Tertiapin Q is a peptide derivative of the honeybee venom peptide and inhibitor of inwardly rectifying potassium (Kir) channels, tertiapin.1 It inhibits heteromultimeric potassium channels composed of G protein-activated inward rectifier potassium channel 1 (GIRK1) and GIRK4, also known as Kir3.1 and Kir3.4, respectively, as well as the inward-rectifier potassium channel 1 (Kir1.1; Kis = 13.3 and 1.3 nM, respectively).2 Tertiapin Q inhibits voltage-stimulated hyperpolarization and increases action potential duration in mouse dorsal root ganglion neurons in a concentration-dependent manner.3 It inhibits BK-type potassium channels in Xenopus oocytes expressing the human BK channel α subunit (IC50 = 5.8 nM).

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
