Dns reagent full form
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. WebThe colour of the reagent changes from yellow to orange or red, depending upon the concentration of reducing sugar present. The DNSA test can detect concentrations of glucose between 0.5mM (0.09% glucose w/v) and 40 mM (0.72% glucose w/v). Because it is an unfamiliar product to many in the UK, this document explains how DNSA reagent
