aptamers, or single stranded oligonucleotides, are produced by systematic evolution of ligands by exponential enrichment, abbreviated as selex. in the amplification and regeneration step of selex technique, dsdna is conversed to ssdna. asymmetric pcr is one of the methods used for the generation of ssdna. the purpose of this study was to design a random dna library for selection of aptamers wit...

data not shown). Figure 1 demonstrates the two alleles of exon 15 of hMLH1 obtained with and without the modifications described above. The modified technique resulted in unequivocal resolution in the complete absence of artifactual bands. Representative samples of hMLH1 exon 15 were subcloned (TA Cloning® Kit; Invitrogen, San Diego, CA, USA) and sequenced following manufacturer’s instructions ...

Construction of a random ssDNA sublibrary is an important step of the aptamer screening process. The available construction methods include asymmetric PCR, biotin-streptavidin separation, and lambda exonuclease digestions, in which PCR amplification is a key step. The main drawback of PCR amplification is overamplification increasing nonspecific hybridization among different products and by-pro...

amide gel electrophoresis (PAGE) on a 180× 160× 1.5-mm 10% polyacrylamide gel. The separated DNA strands were subsequently visualized by staining with either EtdBr or silver (2). Separation of the DNA strands before electrophoresis using streptavidin paramagnetic beads consistently yielded single-stranded products upon SSCP analysis (Figure 1). Treatment of DNA strands with S1 nuclease before S...
