AI Technical Summary

Problems solved by technology

[0017] (2) Existing chips can usually only diagnose one disease, and the cost of chip detection is relatively expensive, so it is difficult to replace conventional detection methods at present
[0022] Hepatitis virus is a routine item for blood testing in blood stations, but the existing testing methods cannot confirm the above four diseases through one experiment at the same time, and the testing cost is high and the efficiency is relatively low

Abstract

The present invention provides a detection gene chip for diagnosing serveral kinds of hepatitis and new primer with high detection rate for using the gene chip in various subtype amplification. The gene chip includes detection quality controlling system and disease diagnosing system. The chip can be used to detect the virus ites of hepatitis B and hepatitis C and detect hepatitis D, hepatitis E, hepatitis G and TTV simultaneously. It has short detection period, high diagnosis accuracy and low diagnosis cost and may be used in epidemiological investigation and blood detection for identifying hepatitis gene type.

Description

technical field [0001] The technical field that the present invention relates to is a gene chip for hepatitis, especially a gene chip for detecting hepatitis mutation. Background technique [0002] Biochip mainly refers to microanalysis units and systems constructed on the surface of solid chips through planar microfabrication technology and supramolecular self-assembly technology. Biochips can integrate many different functional devices: for example, pretreatment of biological samples, extraction of genetic material, amplification of specific gene fragments, biological probe arrays and capillary electrophoresis to form an overall microfluidic system to achieve Accurate, rapid, and informative screening or detection of compounds, proteins, nucleic acids, cells, and other biological components. The gene chip is the most important type of biochip, which integrates a large number of densely arranged gene probes and can analyze a large number of genes in a short time, so that p...
