Urumin is a 27-amino acid virucidal host defense peptide, originally isolated from the skin of the South Indian frog Hydrophylax bahuvistara. Urumin is virucidal for H1 hemagglutinin bearing human influenza A viruses, in which it specifically targets the conserved stalk region of H1 hemagglutinin, and is effective against drug-resistant H1 influenza viruses that are resistant to oseltamivir, zanamivir and peramivir. Urumin appears to inhibit viral growth by physically destroying influenza virions, and can also protect naive mice from lethal influenza infection in vivo.

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.
