Reference sheet · GI / Gut · CPC catalog code CCKS-008
Reference standards in the GI / Gut class are typically shipped as lyophilized powder and stored desiccated at −20 °C protected from light. Once reconstituted in bacteriostatic water or the assay-appropriate buffer, aliquot and store at −80 °C to minimize freeze–thaw cycles. Confirm handling requirements against your institutional biosafety and radiation protocols before use.
Cholecystokinin, CCK Tetrapeptide (30-33) sits within the GI / Gut research class (CPC reference CCKS-008). Gut peptides engage GPCRs on enteroendocrine cells, vagal afferents, and central nuclei, modulating motility, secretion, satiety, and glucose-dependent insulin release. Investigators typically incorporate Cholecystokinin, CCK Tetrapeptide (30-33) as a reference standard, tool ligand, or substrate in the assay contexts listed above. cAMP HTRF, in vitro islet insulin secretion, and food-intake models in rodents.
Cholecystokinin, CCK Tetrapeptide (30-33) (CPC catalog code CCKS-008) is a synthetic gastrointestinal / gut-hormone peptide in the gi / gut category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.
Published and internal research programs use Cholecystokinin, CCK Tetrapeptide (30-33) as a reference standard in gi / gut workflows — for example, incretin (glp-1 / gip) receptor signaling and appetite and satiety-circuit research. Human clinical evidence is not established.
No. Cholecystokinin, CCK Tetrapeptide (30-33) is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.
In a gi / gut workflow, Cholecystokinin, CCK Tetrapeptide (30-33) is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. cAMP HTRF, in vitro islet insulin secretion, and food-intake models in rodents.
Other reference standards in the same class — commonly cross-referenced during assay design and comparator selection.
