Embodiment 1

[0027] Example 1. Use of detection kits

[0028] Step 1: Extraction of DNA template

[0029]Genomic DNA of oral epithelial cells was extracted by silica gel adsorption.

[0030] Step 2: Real-time quantitative PCR reaction

[0031] Use a fluorescent quantitative PCR detection kit that can detect susceptibility to lung cancer, which contains the following primer pairs and fluorescent probes:

[0032] Sense primer 1: 5'-TAACTGGCATCTTCACTTCT-3' (SEQ ID NO: 1) with a Tm value of 56°C

[0033] Antisense primer 1: 5'-TCCAGATTCCTGGCATTGC-3' (SEQ ID NO: 2) with a Tm value of 58°C

[0034] Sense primer 2: 5'-TTTGCCATTCACTGTGTTGG-3' (SEQ ID NO: 3) with a Tm value of 58°C

[0035] Antisense primer 2: 5'-ATCCTTGCTGCTATCATCA-3' (SEQ ID NO: 4) with a Tm value of 54°C

[0036] Fluorescent probe 1: 5'-CGGCTGCCCTCCCAGAGG-3' (SEQ ID NO: 5) with a Tm value of 64°C

[0037] Fluorescent probe 2: 5'-CAGGCCAAGGCGGAAATGCT-3' (SEQ ID NO: 6) with a Tm value of 64°C

[0038] Sense primer 1, antise...

Embodiment 2

[0044] Example 2. Services that guide people to proactively prevent lung cancer

[0045] At present, Shanghai Zhujian Bioengineering Co., Ltd. has launched this service.

[0046] Step 1: DNA Extraction

[0047] The subjects were consulted before the service, and the subjects signed the informed consent and filled out the questionnaire on living and eating habits. According to the instructions in the sampling box, the oral epithelial cells were sampled with oral swabs, and the DNA of the oral epithelial cells was extracted by silica gel adsorption.

[0048] Step 2: Genotyping Assays

[0049] Using the kit provided by the present invention, the SNP site rs25487 on the XRCC1 gene and the SNP site rs1136410 on the PARP1 gene are simultaneously detected by fluorescent quantitative PCR to determine the genotypes of the two SNPs sites.

[0050] Step 3: Instruct people to be proactive in preventing lung cancer

[0051] Through the analysis of the SNPs genotype of the tested subjec...

Abstract

The invention discloses a reagent box for detecting lung cancer susceptibility. The reagent box comprises a pair of specificity primers for detecting concurrently no. rs25487 SNP site of XRCC1 gene and no. rs1136410 SNP site of PARP1 gene, a specificity fluorescent probe and an ordinary assembly for fluorescent quantitative PCR detection. The reagent box predicts the susceptibility of individuals on lung cancer by detecting and analyzing currently the type of carried gene at SNPs site of individual XRCC1 and PARP1 gene.

Description

technical field [0001] The invention relates to a kit for detecting disease susceptibility, in particular to a kit for detecting susceptibility to lung cancer, through simultaneous detection of X-ray repair cross-complementing gene 1 (XRCC1) Single nucleotide polymorphism (SNP) site and poly (ADP-ribose) polymerase family member 1 (poly (ADP-ribose) polymerase family, member 1, PARP1, also abbreviated as ADPRT) single nucleotide polymorphism Loci to predict an individual's susceptibility to lung cancer. Background technique [0002] Primary bronchial lung cancer, referred to as lung cancer, is one of the most common malignant tumors in the world and a serious threat to human health and life. Tumor cells originate from the bronchial mucosa or glands, and often have regional lymph node and hematogenous metastasis. In the early stage, respiratory symptoms such as irritating cough and blood in the sputum are often present. The speed of disease progression is related to the biol...
