Peptides are built by solid-phase synthesis, then purified and freeze-dried into a lyophilized powder before analysis.
A C18 column separates the sample and detects components by UV absorbance, and purity is calculated from the peak areas.
Mass spectrometry compares the measured molecular weight of the compound with its expected mass as an identity check.
Peptides are supplied as freeze-dried lyophilized cakes, a format chosen for stability in storage and transit.
If your vial features a legacy lot code or you need batch-specific data for published research, contact our team with your lot code and we will help you locate the analytical documentation for that batch.
Every batch ships with its corresponding lot-verified Certificate of Analysis. Review the data for your lot before you order.
