At the detection of the designed 2 group-specific primers sequences that derive from SEQ.NO49-51 and SEQ NO.155-157 respectively of the same deletion mutantion of the Exon19 of EGFR to sample, the detection effect of all agreeing.Main points according to above-mentioned ASPE design of primers, be that 3 ' of specific primer sequence is brought in and come from and 1~6 adjacent bit base of deletion mutantion zone 3 ' end, She Ji different liquid-phase chips respectively, its specific primer sequence difference, and the detected result unanimity, but bring in (Group1) when coming from 1~3 base adjacent with deletion mutantion zone 3 ' end when 3 ' of specific primer sequence, the signal to noise ratio of detected result is better, and its specificity and sensitivity are corresponding higher.The concrete detection data of other analogues are omitted.
More than be at the specifying of possible embodiments of the present invention, but this embodiment is not in order to limiting claim of the present invention, does not allly break away from equivalence of the present invention and implement or change, all should be contained in the claim of the present invention.
