The present invention relates to a kit for quantitative analysis of glycated hemoglobin (HbA1c), and the kit for quantitative analysis of HbA1c according to the present invention has excellent long-term stability of an enzyme reagent and thus has an effect of easily overcoming the disadvantages of the conventional reagents used in enzyme assays (e.g., storage, accuracy, portability, convenience of use, etc.).

Kit for hemoglobin A1C quantitative analysis

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 &#x3b2;-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 &#x3b2;-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.

The present invention relates to a biochemical analysis cartridge having improved operability. More particularly, the present invention provides a biochemical analysis cartridge including an insertion-type sample cartridge and a reaction cartridge receiving the insertion-type sample cartridge, in which, as the sample cartridge is inserted into the reaction cartridge, a reaction solution chamber moves toward a broken part of a covertape so as to automatically supply the reaction solution stored in the chamber. The biochemical analysis cartridge having improved operability according to the present invention can induce the mixing between a sample and a reaction solution by simply inserting them into the reaction cartridge and a reaction thereafter, thereby minimizing the process of a measurer to intervene in the assay, and subsequently improving user convenience and operability.

Biochemical analysis cartridge having improved operability

A sensor for measuring a concentration of a specific protein using a biosensor with a measurement speed improved from a conventional impedance measurement. The sensor is capable of efficiently and accurately measuring impedance generated by a selective binding to the protein by Fourier-transforming an electric current signal obtained by applying a potential signal of a delta function waveform. The device for measuring a protein using a biosensor is capable of measuring concentration of the protein with accuracy, measurement time is shortened and the concentration of protein can be accurately measured by removing the influence of dispersion.
