Intact mass, sequence confirmation, peptide mapping, impurity identification, content, counter-ion, water, aggregates, stability and method validation, on the same instruments as our routine peptide testing. For compounders, manufacturers and research groups.
Measured molecular mass of the intact peptide against the theoretical mass for the sequence. Details
Fragment-ion evidence that the peptide has the stated sequence. Details
Enzymatic digest and LC-MS/MS to confirm primary structure and locate modifications on peptides and proteins. Details
Profile of impurities above the reporting threshold, with mass assignment of each. Details
Amount of peptide per vial or per gram, against a qualified reference standard. Details
Dimer and higher molecular weight species in proteins and peptides. Details
Purity, content and appearance at defined time points under stated storage conditions. Details
Development and validation of HPLC and LC-MS methods for a specific peptide or preparation. Details
Send the sequence, modifications and the question you need answered. We confirm the approach, the sample amount and the price before any work starts. Routine services report in 3 to 5 business days; studies run to the agreed protocol.
