The test kit comprises 22 pairs ofamplification primers and can specifically amplify 22 common locus regions of the safe medication gene for children; the 22 single-base extension primers are used for detecting genotypes of 22 loci of the safe medication gene for children; in addition, the test kit comprises a special reagent for pretreatment and detection. The test kit provided by the invention can realize one-hole detection ofdifferent genotypes of 22 common loci related to clinical safe medication genes for the children, and has the advantages of high sensitivity, strong specificity, high accuracy, simple and convenient operation, low cost, high throughput, rapid detection, automatic result interpretation and easy clinical popularization and application. The test kit provided by the invention can be applied to gene detection of safe medication for the children, provides a reliable detection system and test kit for safe medication for the children, and has important clinical application value and good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of molecular diagnosis, and in particular relates to a primer sequence and a kit for detecting children's safe medication genes based on a matrix-assisted laser desorption ionization mass spectrometry (MALDI-TOF) platform. Background technique [0002] Relevant data show that among the more than 3,500 kinds of pharmaceutical preparations in my country, the special dosage forms for children only account for 1.7%; relevant data from the State Food and Drug Administration show that in the drug clinical trial registration project, there are more than 160,000 domestic drug registration information, including children's drugs. There are only 2,698, accounting for only 1.63% of all drugs; children's drugs registered in clinical trials account for only 2.35%, while the number in developed countries in Europe and the United States exceeds 20%. At the 2018 China Children's Safe Medication Conference held recently, it w...

Problems solved by technology

Fluorescence quantification combined with melting curve method has limited single-well detection throughput, and can only detect known mutations at a small number of sites. Specific primers need to be designed for each mutant genotype at each site; multi-hole and multiplex per well is required to cover common sites. Detection, multiple probe design requirements are high, the technology is difficult, the cost of detection probes is high, and the results are interpreted manually, which is prone to misjudgments; the reverse dot hybridization system needs to design probes for each locus and each genotype, and the cost High, the resolution depends on the effectiveness of the probe, it is prone to non-specificity, and the detection process is long, the operation is complicated, the system is open, and the samples are easily contaminated; the Sanger sequencing method is the gold standard for sequencing, but the process is long, the operation is complicated, and requires Manual interp
