Fig. 1From: DAR-PCR: a new tool for efficient retrieval of unknown flanking genomic DNASchematic depiction of DAR-PCR. Primary PCR is performed using SSP1 and the ISA primer; and the secondary PCR is performed using SSP2 and SSP3. The bud heterologous to the known DNA is indicated by the up-ended arrow. The solid lines denote known sequences; Dotted lines denote unknown sequences. SHSC: slightly high-stringency (60℃) cycle; LSC: low-stringency (25℃) cycle; MSC: moderate-stringency (55℃) cycle; HSC: high-stringency (65℃) cycle. The PCR primers are indicated by numbered arrows, and their locations in relation to the relevant strand of genomic DNA are shown on top of the diagram in Step 1Back to article page
