Glycerol [Glycerin or Glycerine, C3H5(OH)3] is widely used in foods, beverages and pharmaceutical formulations. It is also a main by-product of biodiesel production. Simple, direct and automation-ready procedures for measuring glycerol concentrations find wide applications. BioAssay Systems' glycerol assay uses a single Working Reagent that combines glycerol kinase, glycerol phosphate oxidase and color reactions in one step. The color intensity of the reaction product at 570nm or fluorescence intensity at ex/em = 530/585nm is directly proportional to glycerol concentration in the sample. This product is for Research Use only and is not intended for diagnostic purposes.
