Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a high-throughput quantitative detection method for biomolecules. Background technique [0002] In biological research and clinical diagnosis, it is often necessary to know how many biomolecules and their contents are contained in research or clinical specimens. Before the advent of high-throughput quantitative detection methods (highthroughput detection methods), it is necessary to know how many biomolecules exist in a sample, and how many times the sample needs to be tested. The number of is often limited, it is difficult to implement too many detections, and it is extremely difficult to obtain a large amount of detection information. Therefore, high-throughput quantitative detection technology can not only greatly improve the detection efficiency of biological research and experimental diagnosis, but also greatly improve the information abundance that can be obtained ...

Problems solved by technology

[0007] Although xMAP technology has some significant advantages over Biochips technology, such as almost no steric hindrance effect, fast hybridization reaction and high efficiency; the repeatability is greatly improved, xMAP can greatly improve the detection of multiple microspheres of the same color by repeated detection However, xMAP technology also has some significant deficiencies: (1) The detection throughput is limited. Due to the fluorescent coding, a maximum of 100 polypropylene microspheres of different colors can be obtained. xMAP’s The detection throughput cannot exceed 100 kinds of TM / test; (2) Application development is difficult and costly. For each type of TM detected by xMAP, two different BREs need to be developed, which increases the difficulty, cycle and time of application development. (3) There is no accurate basis for quantitative analysis. In xMAP technology, the fluorescence intensity of each microsphere-TM-fluorescent reporter complex can be measured, and multiple same-color The proportion of microspheres bound with fluorescent reporter molecules in the microspheres, this information can be used to analyze the content of the corresponding TM, but because the amount of cross-linked BRE in each microsphere cannot be exactly the same, according to Microsphere-TM- There will be a large error in the quantification of the fluorescence intensity of the fluorescent reporter molecular complex. Due to the randomness of sampling, the microspheres collected for each analysis are different, so the proportion of luminescent microspheres for each test cannot be exactly the same. Therefore, xMAP can only conduct quantitative analysis in a statistical sense based on the above two indicators, but cannot give a quantitative formula with direct relationship
