Description

Fructosyl Peptide Oxidase (FPOX) is a specialized oxidase used for the determination of glycated proteins and glycated peptides. It specifically recognizes and oxidizes fructosyl-peptide structures, generating detectable hydrogen peroxide during the reaction. This enzyme offers advantages such as high stability, strong selectivity, and convenient use. FPOX provides reliable analytical support for clinical diagnostics and research, making it an important enzymatic tool for studies of glycated proteins.
