Figure 1From: Sensitivity of a real-time PCR method for the detection of transgenes in a mixture of transgenic and non-transgenic seeds of papaya (Carica papayaL.)Genomic DNA extraction from dry papaya seeds. A) Using six different techniques (Lane 1: DNeasy Plant Mini kit; 2: TRIzol; 3: Blank; 4: ‘Normal’ CTAB; 5: QIAcube; 6: Promega Maxwell 16). B) Using modified CTAB extraction procedure (Lane 1: ‘Rainbow’; 2: ‘SunUp’; 3: ‘Waimanalo’). M: 1 kb DNA ladder (Fisher Scientific).Back to article page
