CCK (27-33) (non-sulfated)
(Synonyms: Cholecystokinin (27-33) (non-sulfated)) 目录号 : GC18384A C-terminal fragment of CCK
Cas No.:47910-79-2
Sample solution is provided at 25 µL, 10mM.
CCK (27-33) is a C-terminal fragment of CCK , a peptide hormone found in the intestine and brain that stimulates digestion, mediates satiety, and is involved in anxiety. Non-sulfated CCK (27-33) inhibits binding of [3H]naloxone in rat cerebellum membranes (IC50 = 4 uM) and inhibits electrically-stimulated contraction of isolated guinea pig ileum (IC50 = 17 uM), an effect that can be reversed by naloxone. Unlike sulfated CCK (27-33), the non-sulfated form does not reduce exploratory behavior in mice when administered at doses up to 1 uMol/kg.

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。
