Quality Assurance

In scientific research, data integrity depends on reagent integrity. We implement rigorous quality control to ensure every vial meets the highest standards.

HPLC Analysis

High-Performance Liquid Chromatography (HPLC) determines peptide purity. We guarantee minimum 99% purity for all catalog items, ensuring impurities like deletion sequences or incomplete synthesis byproducts are minimized.

Purity Standard ≥99%

Mass Spectrometry

Mass Spectrometry (MS) verifies molecular weight and peptide identity. This confirms the amino acid sequence is correct and matches the theoretical mass.

Molecular Confirmation
100% Verified

Certificate of Analysis (COA)

Transparency is key. A Certificate of Analysis is available for every batch we produce. Download the COA directly from the product page before purchase.

Storage & Handling

To maintain peptide quality after delivery, we recommend the following:

Lyophilized Storage

Store at -20°C immediately upon receipt

Light Protection

Keep away from direct sunlight at all times

Freeze-Thaw Cycles

Minimize cycles to preserve peptide integrity
