Description
Description & Mechanism
Pancragen (KEDW / KEDW-NH2) is studied in vitro as a pancreas-directed short-peptide probe. In aged human pancreatic cell cultures it has been reported to increase expression of proliferation markers (Ki-67, PCNA) and matrix metalloproteinases, and to alter apoptosis-associated proteins, used experimentally to study acinar/islet differentiation and cell-renewal signalling.
It functions as a molecular tool for probing transcriptional control of pancreatic endocrine/exocrine differentiation and glucose–insulin axis biomarkers in cellular and preclinical models. Observed effects depend on concentration, model system and exposure conditions; no physiological outcome is implied.
Applications in Research
- In-vitro study of pancreatic acinar / islet cell differentiation and proliferation/apoptosis markers
- Preclinical (rodent / aged-primate) models of pancreatic functional decline
- Investigation of peptide effects on glucose–insulin axis biomarkers in experimental systems
- Probe for tissue-specific transcriptional regulation

Handling, Reconstitution & Stability
- Weigh under dry conditions; peptide is hygroscopic
- Reconstitute in sterile water or appropriate buffered aqueous solution depending on assay requirements
- Avoid vigorous agitation during dissolution
- Filter sterilize if required (e.g. 0.22 µm) prior to use
- Aliquot and store reconstituted solutions at –20 °C or below to minimise degradation
- Avoid repeated freeze–thaw cycles
Precautions & Notes
- Confirm whether the supplied material is the free-acid (KEDW) or amidated (KEDW-NH2) form against the batch CoA; molecular weights differ
- Experimental behaviour is dependent on concentration, model system and exposure conditions
- Prolonged exposure to light, elevated temperature or aqueous environments may reduce stability
- Intended strictly for laboratory research use; not for human or veterinary application
