Fructose is a monosaccharide found in many foods and is one of the three most important blood sugars along with glucose and galactose. Fructose is the sweetest naturally occurring sugar, estimated to be twice as sweet as sucrose. In Assay Genie's Fructose Assay Kit, free fructose is enzymatically converted to Beta-glucose, which is then specifically converted to a product that reacts with GenieRed Probe to generate color (570nm) and fluorescence (Ex/Em=535/587nm). The kit provides a rapid, simple, sensitive, and reliable method suitable for high throughput assayof D-fructose.
