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.
Fully dissolved and sterilized before use.
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).
It is widely used as an essential nitrogen source in industrial fermentation for producing antibiotics, extracellular proteins, interferon, and diphtheria toxoid, as well as serving as a key component of casein tryptone media for microbial sterility testing.
The Pharmaceutical grade features a total nitrogen level of ≥8.0% and amino nitrogen of ≥2.5%. The Reagent grade offers higher nitrogen contents (total nitrogen ≥12.0%, amino nitrogen ≥3.0%) and guarantees pellucid clarity in high-pressure acid solutions and 2% solubility solutions.
Yes. While our standard physicochemical indices represent general specifications, we can fully customize the product parameters according to the specific requirements of our customers.
The tryptone powder must be fully dissolved in water and properly sterilized prior to application in culture media or fermentation processes.
We offer 25kg compound paper bags or cardboard buckets for bulk orders. Reagent-grade products are packaged in 250g plastic bottles. We also support custom measurement requests and OEM packaging options.
