WebJul 13, 2016 · Fortunately there is a reagent called 3,5 Dinitrosalicylic acid, or DNS , that is super helpful during these glucose assays. After incubating our bacteria in a CMC media so it has a cellulose source to degrade and feed off, we can add DNS so it reacts with the glucose released. Web• Colour Reagent: 96 mM 3,5-Dinitrosalicylic Acid (DNSA) with sodium potassium tartrate solution - Slowly dissolve 2.18 g of DNSA (MW=228.1 g/mol) in 80 mL of 0.5 M NaOH by heating and stirring at 70º C. - Add 30 g of sodium potassium tartrate (MW=282.2 g/mol) and stir until dissolve.
