Fig. 1From: Frequencies of genetic polymorphisms related to triptans metabolism in chronic migraineGenotyping of CYP1A2*1F by pyrosequencing technology based on the sequencing-by-synthesis method. The sequence of interest is analyzed by the instrument which produces a graphic (pyrogram) reporting the nucleotides inserted in the fragment of DNA synthesized. Reverse-complement sequence has been analyzed. Theoretical pyrograms are reported (left panel). The observed sequences are shown in the right. Region including the SNP of interest is highlighted in yellowBack to article page
