Sample solution is provided at 25 µL, 10mM.
Motilin (26-47), human, porcine is an endogenous motilin receptor ligand with Ki and EC50 of 2.3 nM and 0.3 nM in a Chinese hamster ovary cell line.
[Bpa1,Ile13]motilin is a full agonist at the motilin receptor that increases intracellular calcium in a concentration-dependent manner (EC50 = 1.5 ± 0.4 nM)[1]. Motilin binds with high affinity (IC50 0.7± 0.2 nM) to receptors on smooth muscle cells. Motilin selectively activates G(q) and G(13), stimulates G alpha(q)-dependent phosphoinositide (PI) hydrolysis and 1,4,5-trisphosphate (IP(3))-dependent Ca2+ release, and increases cytosolic free Ca2+. Motilin induces a biphasic, concentration-dependent contraction (EC50 = 1.0 +/- 0.2 nM), consisting of an initial peak followed by a sustained contraction[2].

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。
