Embodiment 1

[0033] Embodiment 1, the preparation of kit

[0034] The detection kit of the present invention designs specific amplification primers and sequencing primers for CYP3A5*3 and NPPA (T2238C), and is used for constant temperature amplification and pyrosequencing detection. The design of primers based on the recombinant enzyme polymerase amplification technology is one of the keys of the present invention. The primer design of this technology cannot be carried out by auxiliary software, and can only rely on manual design. In order to ensure the amplification speed and detection sensitivity, the primer length should be controlled at 30-35 bp. If the primer design is too short, non-specific amplification will easily increase and cause false positives. If the primer design is too long, it will easily lead to failure of amplification. Gene polymorphism sequence is subject to the public sequence in Genebank.

[0035] The NPPA gene sequence is as follows:

[0069] Embodiment 2, pyrophosphate detection

[0070] The instruments adopted in the present invention are as follows: PCR amplification instrument: ABI 2720 PCR instrument;

[0071] Pyrosequencer: Wuhan First Biotechnology Co., Ltd.

[0072] (1) Reagent preparation (reagent preparation room)

[0073] Take out the reagent in advance, vortex reagent 1 for 15 seconds, and centrifuge at low speed for later use. Add 440ul of reagent 1 directly to reagent 2 (lyophilized), and vortex for 15 seconds to mix well. Determine the number of reactions N, N = number of samples to be tested (n) + number of quality control products (1) + blank control. It is recommended to conduct positive control and blank control analysis for each PCR experiment at the same time. Then the reaction solution was dispensed into PCR reaction tubes at 20 μL / tube.

[0074] (2) Sample testing (sample preparation room)

[0075] Add the sample DNA, positive control and blank control into the PCR reaction tube ...

Abstract

The invention discloses a detection kit and a detection method for calcium ion antagonist metabolism marker and application thereof. The kit comprises the following components: a CYP3A5 * 3 amplification primer, a CYP3A5 * 3 sequencing primer, an NPPA (T2238C) amplification primer, an NPPA (T2238C) sequencing primer and a positive control. According to the invention, CYP3A5 * 3 and NPPA (T2238C) are amplified through multiple RPA in one tube, so that a large number of amplification products are rapidly and effectively generated at a constant temperature. Single-stranded DNA is specifically captured through amino-labeled single-stranded DNA directly combined with carboxyl modifiers, after washing, sequencing primers and sequencing raw materials are added to perform pyrosequencing, damage of strong alkaline reagents to amplified fragments is reduced, the sequencing process is simplified, and the sequencing time is shortened.

Description

technical field [0001] The invention relates to a detection kit for a calcium ion antagonist metabolic marker, a detection method and an application thereof, and belongs to the field of gene detection. Background technique [0002] At present, there are five categories of antihypertensive drugs commonly used in clinical practice: diuretics, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, β-blockers, and calcium ion antagonists. Drug metabolism in the body involves a variety of drug-metabolizing enzymes, transporters, and receptors, and their genetic polymorphisms ultimately lead to the therapeutic effect, adverse development, and risk factors when patients take the same drug in the same way. There are obvious individual differences in drug tolerance and other aspects. [0003] Calcium antagonists are chemicals that lower blood pressure by blocking calcium channels. It can selectively inhibit Ca2+ from entering the cell through the calcium channel o...
