2.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Biological Activity

Description Caerulein (Ceruletide, Cerulein, FI-6934), a cholecystokinin (CCK) receptor agonist, is a safe and effective cholecystokinetic agent and small bowel and exocrine pancreatic stimulant. Caerulein (FI-6934) can be used to induce animal models of acute pancreatitis.
Targets
CCK receptor [2]
In vivo

Low doses of the cholecystokinin agonists caerulein (0.00001 and 0.0001 mg/kg) elicits reduction of the nalaxone-induced jumping. The inhibition of jumping induced by caerulein is reduced with the selective cholecystokinin antagonists MK-329 and L-365,260. It is concluded that cholecystokinin mechanism(s) may be involved in its dependence, that the agonists may act on a presynaptic receptors.[2]
