Application Notes

In this app note, we perform amino acid hydrolysis of proteins to identify and quantify each amino acid utilizing a safe and rapid amino acid hydrolysis protocol.

Protein analysis plays a large role in the production of foods, pet foods, and even pharmaceutical medicines. But first, the amino acids in the protein must be broken down.

Peptide therapeutics are held to high regulatory standards. Discover Prep was used to hydrolyze the amino acids of a peptide in only 15 minutes, instead of 24 hours.

In this study, SPME Arrow sample preparation was tested for the analysis of furan and alkylfurans in baby formula and coffee samples.

Classical protocol of amino acid hydrolysis needs up to 24 h of reaction time. Using the Discover Prep, the same level of acid and base hydrolysis was achieved in minutes.
