Abstract

The invention discloses a liquid chip kit for detection of a lung cancer. The liquid chip kit comprises coating microspheres, a biotin-labeled detection antibody, streptavidin-phycoerythrin, a reaction buffer solution and a dilution buffer solution, wherein the coating microspheres comprise at least two selected from the group consisting of a microsphere coating a CRP capture antibody, a microsphere coating a Prolactin capture antibody, a microsphere coating a CEA capture antibody, a microsphere coating an NSE capture antibody, a microsphere coating a CK19 capture antibody, a microsphere coating an Axl capture antibody and a microsphere coating an ADAM8 capture antibody, the microspheres coating different capture antibodies have different color codes, and detection antibodies correspond to the capture antibodies. The liquid chip kit provided by the invention has the advantages of high sensitivity and accuracy, rapid detection, good stability and low cost.

Description

technical field [0001] The invention relates to the field of medicine and biology, in particular to a liquid phase chip kit for detecting lung cancer. Background technique [0002] In recent years, the incidence of cancer in my country has shown an obvious upward trend, accounting for more than 20% of the causes of death, ranking first among all causes of death. The World Health Organization predicts that by 2020, there will be 20 million new cancer cases and 12 million deaths, most of which will occur in developing countries. If no effective prevention and control measures are taken, it is estimated that by 2020, the total number of new cancers and cancer deaths in my country will reach about 3 million, and the total number of patients will reach 6.6 million. [0003] Lung cancer is currently the malignant tumor with the highest morbidity and mortality worldwide. In the past 20 years, due to vigorous promotion of smoking cessation, the incidence of male lung cancer in Eur...
