Cholecystokinin, CCK (27-33)

Cholecystokinin, CCK (27-33) (CPC catalog code CCKS-007) 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 (27-33) 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 (27-33) 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 (27-33) 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.

Store lyophilized at −20 °C. Reconstitute in acidified water (0.1% acetic acid) for stability. Follow your institution's standard operating procedures for handling synthetic peptides.

This kindr reference page mirrors CPC Scientific's catalog metadata for CCKS-007. The upstream reference sheet — including sequence, purity, MW, and application notes where published — is linked from the buy panel. All orders placed on kindr Peptides ship internationally under research-use terms only.

Research-grade peptides in the CPC catalog are synthesized by solid-phase peptide synthesis (SPPS), purified by preparative RP-HPLC, and characterized by analytical HPLC and mass spectrometry. Typical purity is ≥95%; certificate of analysis is available on request.
