Abstract

See full text

Disclosed is a hemolysis reagent composition for the quantitative analysis of glycated hemoglobin (HbAlc) via an enzymatic method. The hemolysis reagent compositions of the present invention containing a zwitterionic surfactant and a nitrous compound considerably accelerate hemolysis rate due to the presence of the zwitterionic surfactant, and also induce the N-terminal β-chain of hemoglobin released by hemolysis to be exposed to the outside of the hemoglobin molecule and assists the participation of a greater number of molecules in the reaction, thereby improving reaction sensitivity and reaction rate of the glycated hemoglobin, and the nitrous compound makes the protein structure of the hemoglobin flexibly modified so that the amino acid sequence of the N-terminal β-chain of hemoglobin can be readily cut off, thereby significantly reducing the entire time required for the measurement and improving the accuracy of the measurement.
