Description

Peptone is a complex mixture of polypeptides and amino acids produced by the enzymatic or acidic digestion of proteins. This versatile biochemical is a fundamental nutrient source, providing essential nitrogen and carbon for microbial growth and cell culture. It is a critical raw material for the biotechnology, pharmaceutical, and food industries, where consistent quality and reliable supply are paramount for successful fermentation, diagnostic media preparation, and research applications.

Application

• Microbiological Culture Media: A primary nitrogen source for the preparation of nutrient broths, agars, and selective media for bacterial and fungal cultivation.
• Fermentation & Biotechnology: Serves as a key growth supplement in fermentation processes for the production of antibiotics, enzymes, vaccines, and other biologics.
• Pharmaceutical & Diagnostic Manufacturing: Used in the formulation of culture media for vaccine production, sterility testing, and diagnostic kit components.
• Cell Culture & Tissue Engineering: Provides essential nutrients as a supplement in serum-free and complex media for mammalian and insect cell lines.
• Food & Flavor Industry: Acts as a flavor enhancer and nutrient supplement in processed foods, savory flavors, and yeast extracts.
• Research & Development: Employed in laboratories for microbiological assays, enzyme studies, and as a standard component in various biochemical experiments.

Quality Control

Our Peptone is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot is tested against rigorous specifications for key parameters including total nitrogen, amino nitrogen, clarity, pH, and microbiological bioburden. Certificates of Analysis (COA) detailing these results are provided with every shipment. We can supply grades suitable for general laboratory use, fermentation, and GMP-compliant pharmaceutical applications.

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 securely sealed after each use to prevent caking and degradation due to moisture absorption.
