Glycated Serum Protein

Assay Principle
Glycated Serum Protein Assay uses proteinase K to digest GSP into low molecular weight glycated protein fragments (GPF), and uses specific fructosaminase™, a microorganism originated amadoriase to catalyze the oxidative degradation of Amadori product GPF to yield PF or amino acids, glucosone and H2O2. The H2O2 released is measured by a colorimetric Trinder end-point reaction. The absorbance at 546-600 nm is proportional to the concentration of glycated serum proteins.

Features
enzymatic assay for glycated serum protein provides improved specificity and reliability compared to conventional NBT-based methods. The assay is highly precise with a total CV ≤ 1.3%. The assay offers extensive linearity up to 1354 μmol/L. The assay has no significant interference from: ascorbic acid (5 mg /dL); bilirubin (7.5 mg/dL); bilirubin conjugated (5 mg/dL); glucose (2400 mg/dL; hemoglobin (200 mg/dL); triglycerides (2000 mg/dL); and uric acid (35 mg/dL).
