Tryptose Phosphate Broth, insect cell culture tested

Application

In addition to its use for the growth of fastidious micro-organisms, Tryptose Phospate Broth (TPB) has been studied as supplement for the preparation of media that supports vaccine production in BHK-21 cells and the growth of SF21 insect cells in high-density perfusion culture stirred-tank bioreactors.

Tryptose Phosphate Broth has been used as a supplement: in Eagle?s minimum essential medium alpha for growing Vero cellsfor Vero-CCL81 cells in porcine epidemic diarrhea coronavirus propagationin Dulbecco modified Eagle medium in LR7cells for mouse hepatitis virus propagationin Glasgow minimum essential medium (GMEM) for Madin-Darby canine kidney (MDCK) cells.

Components

Tryptose Phosphate Broth (TPB) is composed of four components: Tryptose (20g/L); Dextrose (2g/L); NaCl (5g/L) and Disodium Phosphate (2.5g/L) typically adjusted to pH 7.3. The tryptose component is a peptone (mixture of amino acids and short peptides) derived by the mixed enzymatic hydrolysis (pancreatic enzymes) of the milk protein casein. This hydrolysate provides a source of amino acid based nutrients and survival factors that support the growth of fastidious micro-organisms such as Brucella, Streptococcus, and Neisseria; as well as eukaryotic cells such as insect and animal cells. Dextrose provides a fermentable carbohydrate that can be used by fastidious mico-organisms. Sodium chloride maintains the osmotic and ionic equilibrium and disodium phosphate provides the basic buffering capacity.

General description

Tryptose Phosphate Broth (TPB) comprises pyrimidine based components and is crucial for pyrimidine synthesis and electron transport chain in cells. In chick embryo fibroblast, it alleviates chloramphenicol inhibition.
