Challenges to Design and Develop of DNA Aptamers for Protein Targets. I. Optimization of Asymmetric PCR for Generation of a Single Stranded DNA Library
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...

متن کاملAsymmetric PCR for good quality ssDNA generation towards DNA aptamer production
Aptamers are ssDNA or RNA that binds to wide variety of target molecules with high affinity and specificity produced by systematic evolution of ligands by exponential enrichment (SELEX). Compared to RNA aptamer, DNA aptamer is much more stable, favourable to be used in many applications. The most critical step in DNA SELEX experiment is the conversion of dsDNA to ssDNA. The purpose of this stud...
متن کاملReal-Time PCR: an Appropriate Approach to Confi rm ssDNA Generation from PCR Product in SELEX Process
Background: Aptamers are single stranded DNA (ssDNA) or RNA molecules. The potential of aptamers for binding to the different targets has made them be widely used as the preferred diagnostic and therapeutic tools. DNA aptamers present several advantages over the RNA oligonucleotides due to their higher stability, easier selection, and production. Selection of DNA aptamers which...
متن کاملComparison of the methods for generating single-stranded DNA in SELEX.
The generation of single-stranded DNA (ssDNA) from double-stranded PCR products is an essential step in the selection of aptamers by systematic evolution of ligands by exponential enrichment (SELEX). Magnetic separation with streptavidin-coated beads is always the most commonly used method. Recently, two size separation methods derived from unequal primers with chemical or structural modificati...
