Biotinylation of Deoxyguanosine at the Abasic Site in Double-Stranded Oligodeoxynucleotides

Figure 4

Restriction digestion and gel electrophoresis of the PCR amplified products using SS-G (a), SS-abasic site (b), or the biotinylated DS-G/abasic site (c) as the template. The restriction enzyme MspI which recognizes the CCGG sequence was used to cleave the PCR amplified product.
