Allatostatin A 10 is a peptide that has been identified in the European green crab, Carcinus maenas. It belongs to the A-type allatostatin (A-type AST) family of peptides. It is one of the 25 A-type allatostatin peptides that have been characterized from the neural tissue of C. maenas. The A-type allatostatins in C. maenas have a -YXFGLamide C-terminus, where X is a variable amino acid.
Allatostatin A 10 is found in the brain of C. maenas, and plays a role in regulating physiological processes in response to changing environmental conditions.

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.
