Our Process
From Synthesis to Your Lab
Our rigorous quality assurance process ensures every batch meets the highest standards of purity and identity verification required for in-vitro research.
-
01
Peptide Synthesis
Each compound is synthesised using solid-phase peptide synthesis (SPPS) under controlled laboratory conditions.
-
02
HPLC Purification
Compounds are purified via reverse-phase HPLC to achieve ≥98% purity before lyophilisation.
-
03
Mass Spectrometry Analysis
Identity and molecular weight are confirmed through MALDI-TOF or ESI mass spectrometry.
-
04
Certificate of Analysis
Each batch ships with a CoA documenting purity, sequence verification, and endotoxin levels.
