[0129] According to the method disclosed in CN 101054601A invention patent (an oligonucleotide probe and a gene chip for detecting mutation sites of cytochrome P450 enzymes), it was prepared for detecting rs1057910 (CYP2C9*3), rs4986893 (CYP2C19 *3) and rs1065852 (CYP2D6*10) conventional SSOP gene chip detection system,...
Embodiment 4
[0133] [Example 4] The influence of the introduction of artificial mismatched bases at the 3' end of the allele-specific inner primer on the detection results of the gene chip.
[0134] Select SEQ ID NO: 19 and SEQ ID NO: 20 as alternative sequences of primers in the wild-type and mutant alleles of rs2231142 (BCRP 421C>A), and prepare the primers for detecting the mutation according to the method described in Example 1. Chip A and Chip B.
[0135] The primer sequence (Inner P-W_A) and mutant allele inner primer sequence (Inner P-M_A) of chip A are respectively:
[0136] Inner P-W_A: GACGGTGAGAGAAAACTTAC (no base mismatch)
[0137] Inner P-M_A: AAGAGCTGCTGAGAACT T (no mismatched bases)
[0138] The primer sequence (Inner P-W_B) and mutant allele inner primer sequence (Inner P-M_B) of chip B are respectively:
[0139] Inner P-W_B: GACGGTGAGAGAAAACT A C (The penultimate position introduces a mismatched base)
[0140] Inner P-M_B: AAGAGCTGCTGAGAA T T (The penultimate po...
