Lab Results
ESI-MS and MALDI-TOF confirmation of molecular weight and sequence for every batch we release.
ESI-MS ionizes peptides and measures the mass-to-charge ratio (m/z) of resulting ions. We confirm the monoisotopic and average molecular masses match the theoretical values within ±0.02 Da.
Tandem MS/MS fragmentation identifies and characterizes impurities at sub-1% levels. Deletion sequences, oxidized residues, and synthesis by-products are quantified and reported on every COA.
De novo sequencing via MS/MS fragmentation pattern confirms the exact amino acid sequence. Critical for research reproducibility — any sequence deviation is grounds for batch rejection.
