EHA105 is ideal for genetic transformation of rice, tobacco and several other plants.
United States Biological Corporation Tryptone (BSE-Free) | 500g
Tryptone is a specially formulated enzymatic digest of casein, similar to Peptone from gelatin. It is used to supply higher growth rates when used in molecular biology media preparations such as YPD Broth and Agar. Used as a nitrogen source in culture media for fastidious and non-fastidious organisms. Also used to differentially select bacteria based on carbohydrate intake since Tryptone is carbohydrate deficient.
