Purity & Testing

Every research peptide lot at Peptide Labs N.I. undergoes a defined battery of quality checks:

• RP-HPLC for purity, quantifying the primary peak against the total integrated area. • ESI-MS or MALDI-TOF for identity confirmation. • Karl Fischer titration or TGA for moisture content. • LAL assay for endotoxin. • Visual inspection of the lyophilised cake and reconstituted clarity.

A certificate of analysis accompanies every batch, referencing all measured values against internal release specifications.
