Description

Bacto Trypton is a high-quality enzymatic digest of casein, widely recognized as a premium-grade peptone for microbiological and biotechnological applications. Its consistent composition and high level of free amino acids and peptides make it an essential nutrient source for promoting robust microbial growth and protein expression. This product is indispensable for researchers and manufacturers in the pharmaceutical, vaccine development, and industrial fermentation sectors who require reliable, high-performance culture media components. Its quality ensures reproducible results in sensitive applications such as cell culture and diagnostic media preparation.

Application

• Microbiological Culture Media: A fundamental nitrogen source in the formulation of nutrient broths, agars, and selective media for bacteria, yeast, and fungi.
• Pharmaceutical Fermentation: Used as a key nutrient in fermentation processes for the production of antibiotics, enzymes, vaccines, and other therapeutic proteins.
• Diagnostic Media Production: Essential for manufacturing standardized culture media used in clinical diagnostics, food safety testing, and water analysis.
• Cell Culture & Virology: Serves as a component in complex media for mammalian cell culture and the propagation of viruses for research and vaccine production.
• Industrial Biotechnology: Supports high-density fermentation for the production of biofuels, organic acids, and specialty chemicals.
• Enzyme Stabilization: Acts as a stabilizer and protective agent for sensitive enzymes and biochemical reagents.

Quality Control

Our Bacto Trypton 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 nitrogen content, amino acid profile, solubility, clarity, and microbiological bioburden. Certificates of Analysis (COA) detailing these results are provided with every shipment. The production process adheres to principles of current Good Manufacturing Practice (cGMP) where applicable, supporting its use in regulated pharmaceutical and diagnostic applications.

Storage

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