Crustacean hyperglycemic hormone precursor-related peptide CPRP 2 is found in the water flea Daphnia pulex and is part of the CHHITP isoform. The CHHITP isoform is a member of the arthropod-specific neuropeptide family and is classified under the CHH subfamily, which contains a precursor-related peptide in its prepro-hormone. The CHH subfamily includes peptides involved in various physiological processes, such as ion transport and hyperglycemic activity.
The presence of a signal peptide and a Lys-Arg prohormone convertase cleavage sequence suggests that the precursor protein undergoes processing to produce the Crustacean hyperglycemic hormone precursor-related peptide CPRP 2.

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.
