Our Methodology
The standard is objective.
We do not rely on manufacturer claims. Every peptide lot is subjected to independent verification in a US-based laboratory before it is cleared for release.
01. Synthesis & Purification
Solid-phase peptide synthesis (SPPS) followed by preparative reverse-phase high-performance liquid chromatography (RP-HPLC). Our baseline standard requires ≥ 98% purity, though most lots clear at ≥ 99%.
02. Identity Verification
Mass spectrometry (ESI-MS or MALDI-TOF) is utilized to confirm the molecular weight of the synthesized compound exactly matches the theoretical mass of the target sequence.
03. Cold-Chain Logistics
Finished lyophilized powder is stored in a climate-controlled, dark environment at ≤ –20 °C. All orders are picked, packed, and shipped from this controlled facility to ensure stability during transit.
