Application
This premium tryptone (casein) serves as a key component of casein tryptone media for microbial sterility testing. In industrial fermentation, it acts as an essential nitrogen source to support microbial growth and metabolism. It is widely used in producing antibiotics, extracellular proteins, interferon and diphtheria toxoid. With rich amino acids and stable properties, it optimizes culture conditions, boosts strain activity and ensures steady quality in biopharmaceutical production.
Frequently Asked Questions (FAQ)
What is tryptone (casein) and what is it derived from?
Tryptone (casein) is a hydrolysate derived from casein, the primary protein found in milk. It is produced through enzymatic digestion and provides a rich source of peptides and amino acids essential for microbial growth and fermentation processes.
What are the main differences between pharmaceutical grade and reagent grade tryptone?
The reagent grade has a higher total nitrogen content (≥12.0% vs ≥8.0%) and higher amino nitrogen content (≥3.0% vs ≥2.5%) compared to pharmaceutical grade. Reagent grade also requires pellucid solubility and acid/alkalescence clarity, while pharmaceutical grade specifies a pH range of 5.0–8.0 for a 2% solution.
Can the product specifications be customized to meet specific requirements?
Yes. While the physicochemical index represents our general specification, we offer customization of product parameters to meet individual customer requirements. OEM packaging is also available upon request.
How should tryptone (casein) be prepared before use?
The product must be fully dissolved in the appropriate solvent and then sterilized prior to use. This ensures optimal performance and prevents contamination in culture media and fermentation applications.
What packaging options are available for this product?
Standard packaging includes compound paper bags at 25kg per bag or cardboard buckets for bulk quantities. Reagent-grade products are available in 250g plastic bottles. Custom packaging sizes and OEM packaging can also be arranged based on customer needs.
In which biopharmaceutical applications is tryptone (casein) commonly used?
Tryptone (casein) is widely used in the production of antibiotics, extracellular proteins, interferon, and diphtheria toxoid. It is also a critical component in casein tryptone culture media for microbial sterility testing and serves as a nitrogen source in industrial fermentation to support microbial growth and metabolism.
