Description

Peptone is a complex mixture of polypeptides and amino acids produced by the partial hydrolysis of proteins, serving as a fundamental nutrient source in microbiological and biotechnological processes. Its consistent quality and bioavailability are critical for ensuring reliable cell growth, protein expression, and fermentation yields in research and industrial applications. This product is essential for manufacturers and laboratories in the pharmaceutical, vaccine development, diagnostic media, and food microbiology sectors who require a high-purity, reliable nitrogen source for culture media formulation.

Application

• Microbiological Culture Media: A primary nitrogen and nutrient source for growing a wide range of bacteria, yeasts, and fungi in diagnostic and research laboratories.
• Fermentation and Bioprocessing: Used as a key component in fermentation broths for the production of antibiotics, enzymes, vitamins, and other bioactive compounds.
• Vaccine Production: Employed in cell culture media for the propagation of viruses and cells used in vaccine manufacturing.
• Pharmaceutical Research: Supports cell culture in drug discovery, toxicity testing, and monoclonal antibody production.
• Diagnostic Reagents: A constituent of enrichment broths and agars used for pathogen detection and identification in clinical and food safety testing.
• Enzyme Stabilization: Acts as a stabilizer and protective agent for various enzymatic preparations.

Quality Control

Our Peptone is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. It is tested against stringent specifications for parameters including total nitrogen, amino nitrogen, clarity, pH, and microbiological bioburden. While available in various grades, our production can align with the requirements of Pharmaceutical (USP/EP) and Food Grade (FCC) applications. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee compliance with your specifications.

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 product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent caking and degradation due to moisture absorption.
