Abstract

The invention relates to an EML4-ALK (echinoderm microtubule associated protein like4-anaplastic lymphoma kinase) fusion gene fluorescent quantitative PCR (polymerase chain reaction) assay kit, which is applicable to assay of EML4-ALK fusion gene mutation in lung adenocarcinoma. The kit comprises probes, primers and positive controls, which are specially designed for conserved sequences of 9 fusion variations of the EML4-ALK fusion gene. The kit can be used for quickly and accurately assaying 9 most common EML4-ALK fusion gene variations with high sensitivity, namely 9 fusion variations of 7 variant subtypes, which are subtype 1 (E13; A20), subtype 2 (E20; A20), subtype 3 (E6a / b; A20), subtype 4 (E14; A20), subtype 5 (E2a / b; A20), subtype 6 (E18; A20) and subtype 7 (E14; A20), so that a real-time fluorescent quantitative PCR system for assaying 9 most common EML4-ALK fusion gene variations can be established.

Description

technical field [0001] The invention belongs to the field of molecular biology, and relates to a kit for detecting EML4-ALK fusion gene fluorescence quantitative PCR, which is suitable for detection of EML4-ALK fusion gene mutation in lung adenocarcinoma. Background technique [0002] Lung cancer is a malignant tumor with the highest morbidity and mortality in the world. Over the past 50 years, the incidence and mortality of lung cancer have risen rapidly in countries all over the world, especially in industrialized countries. In 1995, 600,000 people died of lung cancer worldwide, and the number is increasing every year. In 2003, the World Health Organization (WHO) announced that the mortality rate was 1.1 million per year, and the incidence rate was 1.2 million per year. The cause of lung cancer is still not completely clear. Medical statistics show that the main cause of lung cancer is smoking (including second-hand smoke). 80% of male lung cancer and 75% of female lung c...
