Quality Control

Our peptide products are manufactured under strict quality management systems. Each batch of Lysyl-Arginyl-Alanyl-Lysyl-Alanyl-Lysyl-Threonyl-Threonyl-Lysyl-Lysyl-Arginine undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with data from HPLC, MS, and amino acid analysis. Quality standards are aligned with general guidelines for research-grade peptides, and custom synthesis to specific purity grades (e.g., >95%, >98%) is available.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This material is hygroscopic (moisture-sensitive). For extended storage, desiccate under inert atmosphere. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture absorption.
