Enzymatic Fructosamine (Glycated Serum Protein)
Request package insert information
Product Features
The Diazyme enzymatic assay for fructosamine provides improved specificity and reliability compared to conventional NBT-based methods.  The assay is highly precise with a mean intra assay <2% and mean inter-assay CV of <3%.  The assay offers extensive linearity from 30 µmole/L to 1200 µmole/L.  The assay has no significant interference from: ascorbic acid (4 mm); bilirubin (2 mg/dL); glucose (1200 mg/dL); hemoglobin (100 mg/dL); triglycerides (250 mg/dL); and uric acid (15 mg/dL). The reagent is stable for 12 months from date of manufacture when stored @ 2°-8°C.
Assay Principle
The Diazyme enzymatic assay for glycated serum proteins (GSP) uses a proteinase to digest GSP into low molecular weight glycated protein fragments (GPF), and uses Diazyme’s specific Fructosyl Amine-Oxygen Oxidoreductase to catalyze the oxidative degradation of Amadori product of GPF to yield amino acids, glucosone and H2O2. The H2O2 released is measured by a colorimetric Trinder end-point reaction. The absorbance at 600 nm is proportional to the concentration of glycated serum proteins (GSP).
Intended use
The assay kit is for the determination of glycated serum proteins (fructosamine) in human serum. Fructosamine is formed due to a non-enzymatic Maillard reaction between glucose and amino acid residues of proteins. In diabetic patients, elevated blood glucose levels correlate with increased fructosamine formation. Fructosamine is a medium term indicator of diabetic control (2-3 weeks).
