Wholesale High-Quality Tryptone (Casein) from China Suppliers - Premium Pancreatin Digest for Biological Fermentation Factory Manufacturer, Factories
Tryptone (casein), also known as pancreatic digest of casein, is a premium product essential for various applications requiring casein pancreatin or trypsin hydrolysate in culture media. This fine, light yellow powder is derived from high-quality casein, a nutritious protein sourced from fresh milk. Through rigorous purification, enzymatic hydrolysis, and refined filtration, our Tryptone is refined to offer a rich profile of free amino acids, particularly high in tryptophan, and maintains a balanced nutritional composition along with stable physical and chemical properties, As a vital nitrogen source, Tryptone effectively supports microbial growth and metabolic reproduction, making it a key ingredient for crafting diverse microbial culture media. It is extensively utilized in biological fermentation, biopharmaceutical applications, microbiological testing, and laboratory research. Tryptone is an indispensable resource for bacterial culture, strain isolation, and microbial cultivation tailored to varying nutritional requirements across both industrial and scientific settings. Trust in our factory as a leading supplier in China for high-quality Tryptone to meet your research and production needs

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.
Usage
Fully dissolved and sterilized before use.
Packaging
Compound Paper Bag with 25kg/bag or Cardboard Bucket. Reagent-grade products are packaged with 250g plastic bottle (or be packed according to the measurement requirements of customer and OEM Package as well).
Frequently Asked Questions
What are the appearance standards for this Tryptone?
The product is a light yellow or milky white powder. It should be free of caking and any visible extraneous impurities.
What is the difference between Pharmaceutical and Reagent grades?
The Reagent grade offers a higher nitrogen content (≥12.0% Total Nitrogen) compared to the Pharmaceutical grade (≥8.0%) and ensures high-pressure pellucid solubility.
Can you customize the physicochemical specifications?
Yes, while we provide general specifications, we can customize the product properties to meet specific customer requirements.
What are the main industrial applications of this product?
It is primarily used as a nitrogen source in industrial fermentation for producing antibiotics, interferon, extracellular proteins, and diphtheria toxoids.
How should the Tryptone be prepared for microbial testing?
The powder must be fully dissolved in solution and properly sterilized before it is used in culture media.
What packaging options do you provide for bulk and small orders?
Bulk orders are typically packed in 25kg compound paper bags or cardboard buckets. For reagent-grade or smaller needs, we offer 250g plastic bottles and OEM packaging.
