EMSA method, probe thereof and preparation method of probe
A technology of probe and linker sequence, which is applied in the field of EMSA method and its probe and the preparation of the probe, which can solve the problems that the ratio of double-stranded probes affects the development of positive results, the ratio of double-stranded probes is difficult to guarantee, and the cost is high. Achieve the effects of shortening marking time, reducing preparation costs, and overcoming development errors

Embodiment 1
[0042] Embodiment 1, SMAD2
[0043] S1. Preparation of template chain
[0044] The transcription factor binding sequence was directly determined according to the SMAD2 sequence of the HOCOMOCO or JASPAR database, and the obtained transcription factor binding sequence was GTGTCHGKCTR (H=A / C / T; K=G / T; R=A / G). A linker sequence (GGGTCTAGACCC, SEQ ID NO: 1) was added to the 5' and 3' ends of the transcription factor binding sequence, respectively, to obtain a template chain (linker sequence + transcription factor binding sequence + linker sequence, GGGTCTAGACCC + GTGTCHGKCTR + GGGTCTAGACCC, SEQ ID NO: 4) , whose structure is as figure 1 shown, the sequence was sent to a gene synthesis company for synthesis. At the same time, a mutant single chain was synthesized, and the sequence was GGGTCTAGACCC+TCGRTTHGKCG+GGGTCTAGACCC (SEQ ID NO: 7).

Embodiment 2
[0079] Example 2, NFKB3
[0080] The transcription factor binding sequence was directly determined according to the NFKB3 sequence of HOCOMOCO or JASPAR database, and the obtained transcription factor binding sequence was AGTTGGAAATYCCTCCCAGGC. A linker sequence (GCATCATGATGC, SEQ ID NO: 2) was added to the 5' and 3' ends of the transcription factor binding sequence, respectively, to obtain a template chain (linker sequence + transcription factor binding sequence + linker sequence, GCATCATGATGC + AGTTGGAAATYCCTCCCAGGC + GCATCATGATGC, SEQ ID NO: 5) . The sequence was sent to a gene synthesis company for synthesis. At the same time, a mutant single chain was synthesized, the sequence of which was GCATCATGATGC+AGCTAGYCTGACATCACGCTG+GCATCATGATGC (SEQ ID NO: 12).
[0081] The methods of synthesizing primers, PCR-amplified synthesizing double-stranded probes and EMSA in this example are the same as those in Example 1. The LNA-modified sequence of the primer is GcATcATgATgC (lower...
Embodiment 3
[0086] Embodiment 3, C-JUN
[0087] The transcription factor binding sequence was directly determined according to the C-JUN sequence of the HOCOMOCO or JASPAR database, and the obtained transcription factor binding sequence was TCCGTGTTCTGACTCTTGAGGGTCTTC. A linker sequence (GGGCTAGCCC, SEQ ID NO: 3) was added to the 5' and 3' ends of the transcription factor binding sequence, respectively, to obtain a template chain (linker sequence + transcription factor binding sequence + linker sequence, GGGCTAGCCC+TCCGTGTTCTGACTCTTGAGGGTCTTC+GGGCTAGCCC, SEQ ID NO: 6) . The sequence was sent to a gene synthesis company for synthesis. At the same time, a mutant single chain was synthesized, and the specific sequence of the mutant single chain was GGGCTAGCCC+TCCTCGTCGTGTCAGTGGTCTTATGTC+GGGCTAGCCC (SEQ ID NO: 17).
[0088] The method for synthesizing primers, PCR amplification and synthesizing double-stranded probes in this example is the same as that in EMSA Example 1, but the sequences a...
