Embodiment
[0029] The precise detection method of transgenic maize DAS-40278-9 strain-specific quantitative PCR comprises the following steps:
[0030] (1) Synthesize the following primers and fluorescent probes used in conjunction with the primers,
[0031] Upstream primer sequence, DAS-40278-9event-F: 5'-GTCCAGCACGAACCATTGAGT-3'
[0032] Downstream primer sequence, DAS-40278-9event-R: 5'-TTCATTGTATTCTGGCTTTGCTG-3'
[0033] Fluorescent probe sequence, DAS-40278-9event-P: 5'-FAM-CAACAGCACCGTACCTTGAAGCGGAAT-TAMRA-3'.
[0034] The synthesis concentrations of the primers and fluorescent probes in this example were both 10 μmol / l.
[0035] The nucleotide sequences of the above primers and fluorescent probes are designed for a specific site specific to the line of transgenic maize DAS-40278-9 and the product, i.e. the target gene and the flanking site of the recipient maize genome; Accurate detection of DAS-40278-9 transformation events in transgenic maize.
[0036] (2) Prepare the DNA di...
