  • Description

    Phenypressin is a neurohypophyseal hormone identified in Australian marsupials of the Macropodidae family. It is a vasopressin-like peptide characterized by the presence of two phenylalanine residues, distinguishing it from arginine vasopressin, which contains one tyrosine and one phenylalanine. The peptide was isolated and characterized through techniques such as molecular sieving and high-pressure liquid chromatography, with its amino acid composition confirming the structure.

    In evolutionary context, phenypressin, along with lysine vasopressin, is found in macropodids, suggesting gene duplication events in marsupial ancestors. This duplication may have allowed functional diversification, though both peptides retain antidiuretic activity. The presence of phenypressin in Australian marsupials contrasts with the neurohypophyseal hormone profiles of South American marsupials, which contain oxytocin, lysine vasopressin, and arginine vasopressin, highlighting divergent evolutionary pathways among marsupial lineages.

  • 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.
