Embodiment 3

[0093] Example 3 Adapter Synthesis Captured by Multiple Sample Hybridization

[0094] Dilute DNA oligonucleotide single-stranded Adapters1-1 and Adapters1-2 to 100 μM with ultrapure water, then mix 100 μl of diluted Adapters1-1 and Adapters1-2 in a PCR tube, and then place it on a PCR instrument, Run the following program: 95°C for 5 minutes, then turn off the PCR instrument and allow it to cool down naturally for 1 hour, the product is the hybrid capture adapter, such as figure 1 shown. The synthetic method of linker Adapters2, linker Adapters3 and linker Adapters4 is the same as linker Adapters1, as respectively Figure 2-Figure 4 shown.

Abstract

The invention provides a capture probe set for a dementia-related gene, a kit, a library construction method and a use thereof and relates to the technical field of gene detection. The capture probe set contains coding regions of 95 genes and can capture aiming at a specific coding region and perform high-depth sequencing so that target gene sequencing is accurate and a sequencing cost is reduced.The capture probe set can efficiently enrich the target genes in construction of a library, reduce the sample size requirement and also better control the sequencing cost.

Description

technical field [0001] The invention relates to the technical field of gene detection, in particular to a dementia-related gene capture probe set, kit, library construction method and application. Background technique [0002] Dementia refers to a group of clinical syndromes with cognitive impairment as the main clinical manifestation caused by neurodegeneration, cerebrovascular disease, infection, trauma, tumor, nutritional and metabolic disorders, etc., and is more common in the elderly. In addition to various cognitive impairments such as orientation, memory, learning, language comprehension, and thinking, most patients also exhibit abnormal behavior, which will eventually lead to a decline or loss of their work and social life functions. Dementia has a high prevalence rate, high disability and mortality rate, and is an aging disease. It has become the fourth cause of death in the elderly population in western developed countries after cancer, heart disease and stroke. T...
