TB Dry


Tb dry is a single component high nutrient medium formulated
The most important advantage of tb dry is that all components
Separate solutions. tb dry yields 4-7 times more plasmid dna than lb broth.
Formulation per 55g:
12g tryptone, 24g yeast extract, 4g alternate carbon source, 14.8g potassium phosphate
A solution at 55g/liter is clear yellow after autoclaving at 121°c
To maximize yields of recombinant plasmids and cosmids.
Are combined into a single powder, eliminating the need to autoclave two
