Abstract

This invention relates to preparation and detect method of detection protein chip of diabetes autoimmune antibody. The scheme is as follows: a protein chip is a thin glass chip set with multiple reaction tanks on top surface of the said shell and a detection microarray in each of the reaction tank, every micro-array is composed of three different kinds, same size protein micro-solid phase detection chips of GAP, PTP and Insulin. The preparation method is to prepare protein micro-solid phase detection chips to be assembled and the detecting method is to apply indirect fluorescent method for detection.

Description

Technical field: [0001] The invention relates to the field of biomedical research and clinical application, in particular to a diabetes autoimmune antibody detection protein chip, and its preparation and detection methods. Background technique: [0002] Diabetes is currently one of the most serious diseases that endanger human health and quality of life. Its main symptom is a persistent increase in blood sugar concentration, and it endangers health through a variety of serious complications. According to the latest predictions made by the International Diabetes Federation (KDF) on the current situation of global diabetes and the World Health Organization (WHO) on the incidence of diabetes, 130 million people have been diagnosed with type II diabetes in the world, and more than 40 million people in my country . It is estimated that by 2025, the number of diabetic patients in the world will exceed 300 million, and the total number of diabetic patients in my country will be clo...
