Secretin is a neuropeptide hormone that regulates secretion from the stomach, pancreas, and liver.1,2 It binds to the rat secretin receptor (SCT-R; Ki = 3.3 nM) and increases intracellular cAMP (EC50 = 1 nM) in COS cells expressing rat SCT-R.3 It also increases SCT-R phosphorylation 7.2-fold at a concentration of 0.1 μM. Secretin dose-dependently increases the volume of pancreatic secretion and inhibits gastric acid secretion induced by gastrin I in rats when administered at a dose of 100 pmol/kg per hour.4

工作液浓度： mg/ml；
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。
