Description

Peptones, Lactalbumin is a high-purity, enzymatically derived protein hydrolysate primarily sourced from milk. This product is a critical source of amino acids, peptides, and nitrogen, serving as a premium-grade nutrient and growth factor in complex biological systems. It is essential for manufacturers in the pharmaceutical, biotechnology, and microbiology sectors requiring consistent and reliable raw materials for fermentation and cell culture media.

Application

• Microbiological Media Formulation: A key nitrogen source for the cultivation of bacteria, yeasts, and other microorganisms in diagnostic and industrial fermentation processes.
• Pharmaceutical & Vaccine Production: Used as a complex ingredient in fermentation broths for the production of antibiotics, therapeutic proteins, and vaccines.
• Cell Culture Applications: Provides essential nutrients and growth factors in serum-free and low-serum media for mammalian and insect cell culture systems.
• Enzyme Production: Serves as an inducer and nutrient substrate in fermentation processes for industrial enzyme manufacturing.
• Diagnostic Reagents: Employed in the formulation of culture media for clinical microbiology and in-vitro diagnostic test kits.
• Research & Development: A standard component in laboratory media for microbiological research, strain development, and bioprocess optimization.
