Description

Neopeptone is a high-quality enzymatic digest of protein, widely recognized as a premium-grade nutrient source for microbiological and cell culture applications. Its consistent composition and high nutritional value make it an essential component for ensuring robust and reproducible growth in sensitive biological systems. This product is critical for manufacturers and research institutions in the pharmaceutical, biotechnology, and diagnostic industries, where reliable media formulation is paramount for fermentation, vaccine production, and cell line development.

Application

• Microbiological Culture Media: A fundamental nitrogen source for the cultivation of a wide range of bacteria, yeast, and fungi in both research and industrial fermentation processes.
• Vaccine Production: Used in the formulation of complex growth media for the production of viral vaccines and other biologics, providing essential amino acids and peptides.
• Cell Culture & Tissue Engineering: Serves as a key ingredient in serum-free and low-serum media for mammalian cell culture, supporting cell proliferation and protein expression.
• Enzyme and Antibiotic Fermentation: Acts as a nutrient base in large-scale industrial fermenters for the production of therapeutic enzymes, antibiotics, and other secondary metabolites.
• Diagnostic Media: Employed in the preparation of selective and differential agars for clinical microbiology and food safety testing.
• Seed Culture and Inoculum Development: Provides optimal nutrition for building high-density, viable cell banks to inoculate main production fermenters.

Quality Control

Our Neopeptone is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot is tested against rigorous specifications for critical parameters including total nitrogen, amino nitrogen, clarity, and microbiological bioburden. Certificates of Analysis (COA) detailing these results are provided with every shipment. While not a single chemical entity, its quality is assured for applications requiring compliance with cGMP and other relevant pharmaceutical and food-grade guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept sealed to prevent caking and degradation due to moisture absorption.
