Product Description
Cholecystokinin Precursor (24-32) (rat) is a cholecystokinin precursor that is expressed in the heart, lungs, kidneys, as well as the gastrointestinal tract and brain. Cholecystokinin is a brain-gut peptide that stimulates gallbladder contraction and pancreatic exocrine secretion and also works as a neurotransmitter.
V-9-M Cholecystokinin nonapeptide (CAS 99291-20-0) is a research peptide used in pharmacological studies. As a cholecystokinin (CCK) analog, it is employed in neuroscience and gastrointestinal research to study CCK receptor function, satiety signaling, and pancreatic secretion. The compound is supplied for research use only and is not intended for human therapeutic applications. Detailed pharmacological characterization data are limited in the available literature.
Biological Activity I Assay Protocols (From Reference)
Targets
V-9-M Cholecystokinin nonapeptide targets cholecystokinin (CCK) receptors. As a CCK analog, it binds to CCK1 and CCK2 receptors (formerly CCK-A and CCK-B) to modulate gastrointestinal motility, pancreatic enzyme secretion, and satiety signaling in the central nervous system. The compound is used in research to study the physiological roles of CCK in digestion and appetite regulation.
ln Vitro
Detailed in vitro activity data for V-9-M Cholecystokinin nonapeptide are not extensively available. As a CCK receptor agonist, it would be expected to activate CCK receptors in cell-based assays, stimulating signaling pathways such as phospholipase C and intracellular calcium mobilization. Binding affinity and functional potency would be determined using receptor binding and second messenger assays.
ln Vivo
Detailed in vivo activity data for V-9-M Cholecystokinin nonapeptide are not extensively available. As a CCK analog, it would be expected to produce CCK-like effects including stimulation of pancreatic secretion, gallbladder contraction, and inhibition of gastric emptying in animal models. These effects are consistent with the known physiological functions of cholecystokinin.
Enzyme Assay
Specific cell-free enzyme/receptor binding assay protocols for V-9-M Cholecystokinin nonapeptide involve radioligand binding assays using membranes expressing CCK1 or CCK2 receptors. Binding affinity (Ki or Kd) is determined by competitive displacement of a radiolabeled CCK ligand. Receptor selectivity can be assessed by comparing binding to CCK1 versus CCK2 receptors.
Cell Assay
Specific in vitro cell-based experimental protocols for V-9-M Cholecystokinin nonapeptide use cell lines expressing CCK receptors. Cells are treated with the peptide, and receptor activation is assessed by measuring intracellular calcium mobilization, inositol phosphate accumulation, or other downstream signaling events. Functional potency (EC50) is determined from concentration-response curves.
Animal Protocol
Specific in vivo animal experimental protocols for V-9-M Cholecystokinin nonapeptide involve administration to rodents to assess CCK-like effects. Endpoints include measurement of pancreatic secretion, gallbladder contraction, gastric emptying, and food intake. The compound’s effects on satiety and gastrointestinal motility can be evaluated in these models.
ADME/Pharmacokinetics
Detailed pharmacokinetic properties of V-9-M Cholecystokinin nonapeptide are not extensively available. As a peptide, it would be expected to have limited oral bioavailability and rapid degradation by proteolytic enzymes. Pharmacokinetic studies would typically involve intravenous or subcutaneous administration with measurement of plasma concentrations using immunoassay or HPLC-MS methods.
Toxicity/Toxicokinetics
Detailed toxicological data for V-9-M Cholecystokinin nonapeptide are not extensively available. As a research peptide, standard toxicology studies would be required for therapeutic development. The compound is classified for research use only and is not intended for human therapeutic applications.

  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
