Description

Arg-Pro-Lys-Pro-Gln-Gln-Phe-Tyr-Gly-Leu-Met-Nh2 CAS NO 55614-10-3 is a synthetic peptide amide, specifically a fragment of the milk protein casein. This compound is of significant commercial interest due to its role as a precursor for bioactive peptides, particularly casomorphins, which have been studied for their potential physiological effects. It is primarily required by research institutions, pharmaceutical development labs, and nutraceutical manufacturers engaged in peptide synthesis, metabolic research, and the development of functional food ingredients.

Application

• Biomedical Research: Used as a key intermediate or standard in studies investigating opioid peptide pathways, digestive physiology, and casomorphin activity.
• Pharmaceutical Development: Serves as a building block (API intermediate) in the synthesis of more complex therapeutic peptides targeting neurological or gastrointestinal systems.
• Nutraceutical Ingredient Research: Employed in the development and analysis of bioactive peptide supplements derived from casein, focusing on stress relief or digestive health.
• Analytical Standard: Acts as a high-purity reference standard in HPLC, LC-MS, or amino acid analysis for quality control in dairy protein hydrolysates and related products.
• Biochemical Reagent: Utilized in enzymatic studies and as a substrate for proteases to understand casein breakdown and peptide release.

Quality Control

Our Arg-Pro-Lys-Pro-Gln-Gln-Phe-Tyr-Gly-Leu-Met-Nh2 is manufactured under strict quality systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for research and development applications. A Certificate of Analysis (COA) detailing purity (typically ≥95% by HPLC), peptide content, and impurity profile is provided with every shipment.

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); allow the sealed vial to equilibrate to room temperature before opening to prevent condensation. For short-term use, store desiccated at 2-8°C.
