Description

Cholecystokinin-33 (swine) is a cholecystokinin (CCK) fragment. Cholecystokinin-33 (swine) can reduce food intake and gallbladder contraction^[1].

In Vivo

Cholecystokinin-33 (swine, 0.05-0.25 nM/kg; catheterization, for a branch of the abdominal aorta and a branch of the aorta located caudal) has gastrointestinal site specificity in regulating feeding behaviors in male rats. Cholecystokinin-33 swine reduces meal size and increased the satiety ratio at sites supplied by the cranial mesenteric artery^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Male Sprague Dawley rats (400-450 g)^[1]
Dosage:	0.05, 0.15, and 0.25 nM/kg
Administration:	Catheterization, for a branch of the abdominal aorta and a branch of the aorta located caudal
Result:	Reduced meal size (MS) and increased the satiety ratio (SR).
