Question
I plan to submit a peptide sample for Peptide Purity Analysis using High-Performance Liquid Chromatography (HPLC).
- Is a 10mg peptide sample in powder form sufficient for this analysis?
- Will the results of the Peptide Purity Analysis by HPLC be reported in percentage form?
Answer
Yes, a 10mg powder peptide sample is generally sufficient for Peptide Purity Analysis (HPLC). The standard required amount is typically 5-10mg of dry powder.
The results of the Peptide Purity Analysis by HPLC are always reported as a percentage. This percentage is calculated based on the ratio of the main peptide peak area to the total area of all detected peaks in the chromatogram.
