Certificates of Analysis
& Lab Testing
In preclinical research, reproducibility depends entirely on chemical purity and sequence fidelity. Every batch of lyophilized peptides supplied by BioPeptide.online is independently verified by accredited third-party laboratories using HPLC and Mass Spectrometry.
Our 3 Analytical Testing Standards
HPLC Purity >99%
Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) identifies peptide peak area against synthesis truncations, deletion sequences, and chemical diastereomers.
Mass Spectrometry (MS)
Electrospray Ionization Mass Spectrometry (ESI-MS) measures exact mass-to-charge (m/z) ratios to confirm the theoretical molecular weight and sequence identity.
Lyophilized Stability
Vials are freeze-dried with inert nitrogen head-space and sealed with rubber septum caps to protect against atmospheric moisture, oxidation, and enzymatic degradation.
