We are a dedicated team of peptide scientists and supply chain specialists committed to delivering research-grade materials that accelerate discoveries worldwide.
Founded in 2019 in Qingdao, China, Kerisite Peptide began with a simple conviction: researchers deserve access to high-quality peptide materials without compromise.
Our facility combines solid-phase peptide synthesis (SPPS) with advanced purification and analytical verification. Every batch undergoes HPLC and mass spectrometry analysis.
Today we offer 500+ catalog peptides alongside custom synthesis capabilities from milligram to multi-gram scale.
Six pillars that define our commitment to every researcher, clinician, and distributor we serve.
Every product undergoes rigorous HPLC and mass spectrometry analysis.
COA, HPLC chromatograms, and MS spectra included with every order.
Dual warehouses enable fast, temperature-controlled shipping to 35+ countries.
ISO-certified quality management systems and controlled environments.
From milligram samples to multi-gram production to your exact specifications.
Dedicated account managers ensure every inquiry gets a response within 24 hours.
A rigorous five-step workflow ensures every peptide meets our exacting standards before it reaches your laboratory.
Automated SPPS with Fmoc chemistry. Sequences up to 100+ residues with modified amino acids and specialty modifications supported.
Reverse-phase HPLC purification to achieve target purity. Multiple column chemistries for optimal separation.
Every batch verified by analytical HPLC for purity and mass spectrometry for molecular weight confirmation.
COA generated with full HPLC chromatogram and MS spectrum. Lyophilized and sealed under inert atmosphere.
Dispatched from Qingdao or US warehouse via temperature-controlled logistics with dry ice packaging.
Our Qingdao facility houses dedicated synthesis, purification, and analytical laboratories — all under one roof with strict environmental controls.
