Description

Peptones, Liver is a complex enzymatic digest of liver tissue, primarily used as a rich source of amino acids, peptides, and growth factors. This product is essential for providing the necessary nitrogenous nutrients to support the cultivation of fastidious microorganisms in various culture media. It is a critical raw material for industries requiring high-quality, consistent, and reliable biological growth substrates. Key applications span microbiology, biotechnology, and pharmaceutical development, where it serves as a fundamental component in fermentation and cell culture processes.

Application

• Microbiological Culture Media: A key nitrogen source for preparing nutrient broths, agars, and selective media for the isolation and cultivation of bacteria, yeasts, and fungi.
• Fermentation Processes: Used as a complex nutrient to enhance cell density and product yield in industrial fermentations for enzymes, antibiotics, and other metabolites.
• Vaccine Production: Employed in the formulation of growth media for virus propagation and cell culture in biopharmaceutical manufacturing.
• Diagnostic Reagents: A component in prepared culture systems and biochemical test kits used for clinical and food safety microbiology.
• Enzymology & Biochemistry Research: Provides essential nutrients in research media for studying enzyme production, metabolic pathways, and protein expression.
• Cell & Tissue Culture: Serves as a supplement in serum-free or low-serum media formulations to support the growth of certain mammalian and insect cell lines.

Quality Control

Our Peptones, Liver is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for microbiology, chemistry, and performance. We provide comprehensive Certificates of Analysis (COA) that detail parameters such as total nitrogen, amino nitrogen, microbiological purity, and solubility. Our quality commitment supports applications requiring consistency in microbiological growth promotion and fermentation yield.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent caking and degradation due to moisture absorption.
