Pancragen is a tetrapeptide composed of the amino acid sequence Lys-Glu-Asp-Trp (KEDW). It is a synthetic analog derived from a peptide originally isolated from bovine pancreatic cells and has been identified as a potential peptide bioregulator with implications for pancreatic function and age-associated metabolic processes. Aimed at supporting pancreatic function, pancragen can interact with histones and DNA, potentially improving glucose metabolism and insulin production. It may also aid in tissue repair within the pancreas.

Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides

Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.

Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.

Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.

In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.
