Embodiment 1

[0047] Example 1 Primer Design Optimization

[0048] 1) Primer sequence optimization

[0049] According to the site in Table 1, the present invention comprehensively designs PCR primers and single-base extension primers based on software and design experience, uses gDNA as a template to detect the working efficiency of primers, and finally screens out the best PCR primers and single-base extension primers through multiple rounds of design and repeated optimization. For base extension primers, see the primer sequences in Tables 2 and 3 for details.

Description

technical field [0001] The invention relates to the field of gene detection, in particular to a primer set, reagent and / or kit, system and application thereof for detecting lung cancer chemotherapy-related genes. Background technique [0002] Chemotherapy is often accompanied by various adverse reactions. For example, bone marrow toxicity is a very common non-specific toxicity of chemotherapy, manifested as leukopenia, thrombocytopenia (more common with gemcitabine and other drugs), chemotherapy-related anemia (more common with cisplatin and other drugs); Chemotherapy-related vomiting, cisplatin, high-dose cyclophosphamide (≥1000mg / m2) and other drugs, the incidence of vomiting is as high as 90% to 100%; chemotherapy-related diarrhea, in mild cases, can reduce the quality of life of patients, and in severe cases can cause Acid-base imbalance, water-electrolyte disturbance and other complications occur, even leading to death of the patient. Diarrhea is the main dose-limiting ...
