  • Description

    Obestatin is a peptide hormone encoded by the ghrelin gene. It is derived from the same prohormone precursor as ghrelin through posttranslational processing, which includes cleavage and C-terminal amidation. The mature, amidated form of obestatin is a 23-amino acid peptide. In vitro studies demonstrate that obestatin binds with high affinity to the orphan G protein-coupled receptor GPR39, a receptor belonging to the same subfamily as the ghrelin receptor. This binding initiates intracellular signaling, such as stimulating cyclic adenosine monophosphate production. The peptide is detected in tissues including the stomach, jejunum, and pituitary.

  • Storage Guidelines

  • About TFA salt

    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.
