TP4 was related to O. niloticus moronecidin-like peptide (98% identity). Active against Gram-negative V. vulnificus 204, A. hydrophila BCRC 13018, V. alginolyticus, P. aeruginosa ATCC 19660, Gram-positive bacteria S. agalactiae 819, E. faecalis BCRC 10066, and S. agalactiae BCRC 10787 (MIC: 0.03-2 ug/ml). Oreoch-2 has Antibacterial, Antifungal activity. The source of Oreoch-2 is gills, tilapia, Oreochromis niloticus.

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.
