beta-Conglycinin fragment P3 was found in soybean (Glycine max). Bioactive peptides are prepared from both plant and animal sources, with the antihypertensive peptides IAP and VY and the hypocholesterolemic peptide IIAEK derived from wheat gliadin, sardine muscle, and bovine milk α-lactoglobulin, respectively. For soy protein, several bioactive peptides, including the hypocholesterolemic peptide LPYPR, antihypertensive peptide NWGPLV, antioxidant peptide LLPHH, and anti-obese peptide VRIRLLQRFNKRS, were derived from its major constituents, glycinin, and β-conglycinin (BCG).

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.
