Problems solved by technology

[0006] CYP4F2 is the main metabolic enzyme that metabolizes arachidonic acid to produce tetraenoic acid. Recently, a V433M mutation in the CYP4F2 gene was found to reduce the metabolic capacity of arachidonic acid and reduce the production of tetraenoic acid. Enzymatic activity of CYP4F2
CYP4F2 is a monooxygenase of vitamin K, which can oxidize substrates to generate ω-hydroxyl derivatives, and different genotype

Example Embodiment

[0067] Example 1

[0068] Step 1: Preparation of Whole Blood Cell Lysate

[0069] Take 300 μl of peripheral venous blood of the subject, add 700 μl of cell lysate, invert and mix 5 times, centrifuge at 12,000 rpm for 1 minute, discard the supernatant, and place the centrifuge tube upside down on clean absorbent paper for 2 minutes to ensure that the pellet is in the tube , add 300 μl of double-distilled water, and mix by vortexing to form a cell lysis suspension.

[0070] Step 2: PCR Amplification Reaction

[0071] 1. Configure the wild-type reaction system: add 4.8 μl of cell lysis suspension, 5 μl of 2× wild-type amplification buffer and 0.2 μl of polymerase (2.5U / μl) into the PCR tube to form an independent reaction system. Homogenize, centrifuge briefly, and finally gently add 20 μl of liquid paraffin oil along the tube wall to seal the system, as shown in the following table:

[0072] 2x wild-type amplification buffer

Abstract

The invention discloses a kit for detecting SNP (Single Nucleotide Polymorphism) sites related to Warfarin individualized application by combining multiplex PCR (Polymerase Chain Reaction) technology and SNP sensitive molecule switch technology and a detection method using the same. The kit types four SNP sites related to Warfarin application, including rs9934438 SNP site on VKORC1 gene, rs1799853 and rs1057910 SNP sites on CYP2C9 gene, and rs2108622 SNP site on CYP4F2 gene. The kit comprises a wild type 2*amplification buffer, a mutant type 2*amplification buffer, polymerase, a cell lysis solution and glycerol, wherein the two buffers respectively contain corresponding SNP wild type and mutant phenotype sequence specific primers and beta-actin primers; and the four SNP sites can be typed in the two multiplex PCR reactions, thereby providing molecular biology references for reasonable application of Warfarin.
