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.

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.

Other Notes

This Tryptose broth is closely related to Tryptose phosphate broth, but does not contain the phosphate component and it contains a lower concentration of dextrose.

Preparation Note

This formulation contains Tryptose (20 g/L); Dextrose (1 g/L); and NaCl (5g/L) adjusted to a final pH of 7.2.

Spodoptera frugiperda insect cells (IPLB-Sf21-AE) (Sf21), infected with baculovirus expression vectors during their exponential growth phase, are commonly used to produce a variety of heterologous recombinant proteins. In the present study the culture conditions of these insect cells were studied

The in vitro culture of Cowdria ruminantium, the causative agent of heartwater in domestic ruminants, was first achieved in 1985. Culture media were usually supplemented with serum and tryptose phosphate broth, both undefined components, contributing to great variability. Recently, we
