Tryptic soy broth (TSB) is a complex liquid culture medium formulated with enzymatic digests of casein and soybean meal, providing amino acids, peptides, and nutrients that support robust microbial growth. This balanced composition makes it suitable for cultivating a broad spectrum of bacteria and fungi, including both fastidious and non-fastidious organisms.

TSB is commonly used in microbial culture, sterility testing, environmental monitoring, and sample enrichment workflows. Its versatility and reliable performance make it a standard medium in pharmaceutical, food safety, and academic microbiology laboratories.

Our tryptic soy broth (TSB) is supplied as a ready-to-use liquid medium, eliminating in-house preparation and reducing variability between experiments. Each formulation, including those with animal-free soytone, trypticase soy broth, Tween-80, sheep’s blood, and pyridoxal-HCl, is manufactured to precise specifications to ensure consistent nutrient composition and reliable microbial growth.

We manufacture our wide selection of off-the-shelf RUO- and GMP-grade TSB products using validated processes and rigorous quality control testing to ensure sterility, performance, and lot-to-lot consistency. We can also tailor a product to your exact specifications, with custom manufacturing options including modified formulations, antibiotic supplementation (up to 5), alternative fill volumes, peptones, and bulk container formats to meet specialized research, quality control, and industrial microbiology requirements.
