Description
[Ala11,D-Leu15]-Orexin B is a highly potent and selective OX2 receptor agonist with 400-fold selectivity for OX2 over OX1 receptors, possessing EC50 values of 0.13 and 52 nM for human OX2 and OX1 receptors respectively. [Ala11,D-Leu15]-Orexin B increases social novelty seeking and can decrease anxious and depressive behaviour in animal models.

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.
