Description
Technical field
The present invention relates to a kind of detection by quantitative primer of transgenic line, particularly a kind of transgenic paddy rice PA110-15 strain specificity 5 ' end quantitative PCR detection primer and detection method thereof.
Background technology
At present, security about genetically modified food is subject to people and pays close attention to more and more widely, the security of genetically modified food has become the topic that people comparatively pay close attention to, the grain and oil commercially sold, vegetables, the agricultural-food such as melon and fruit also are all got not genetically modified signboard to attract clients, but whether the food bought is non-transgenic food, whether is doped with genetically modified food, the amount of doping is that how many, common human consumers cannot differentiate.
In genetically modified food, the transgenosis of food crop especially receives the concern of people.Differentiate that an effective means of genetically modified crops is that PCR detects insertion gene order, but, the gene that a lot of genetically modified crop material proceeds to also contains the similar gene of this gene or this gene in its non-transgenic parent, can cause interference to the result of PCR.When applying round pcr and carrying out genetically modified crops qualitative detection, according to its specificity, be divided into selective mechanisms method, gene specific method, built specificity method and strain specificity method.Event-specific detection is that the joining region sequence by detecting insertion vector and Plant Genome realizes, due to each Transgenic Plant Lines, all there is the joining region sequence of special exogenous insertion vector and Plant Genome, compare with first three methods, strain specificity has higher specificity and accuracy, the most applicablely does GMO detection.
Patent CN201410081539 discloses transgenic paddy rice PA110-15 strain specificity PCR and detects primer and qualitative checking method and test kit.Patent CN201410081893 discloses transgenic paddy rice PA110-15 external source Insert Fragment flanking sequence and application.These two patents are all that the flanking sequence inserted from transgenic paddy rice PA110-15 is started with, the primer that design detects, reach the object of detection specificity, but in actual applications, whether human consumer not only will understand in its rice bought containing this transgenic strain, and, whether be all the strain of this genetically modified rice, or part is that the amount (content) of doping is how many if also will understand.At present, this primer set by two patents can only do qualitative detection, cannot realize detection by quantitative.
