Aptamers have been identified against various targets as a type of chemical or nucleic acid ligand by systematic evolution of ligands by exponential enrichment (SELEX) with high sensitivity and specificity.
Nucleic acid aptamers selected from a library of random sequences by systematic evolution of ligands by exponential enrichment (SELEX) bind to the chosen ligands with high specificity and affinity [ 1, 2].
These include dyes, chelated metal ions, peptides obtained by phage display technology, combinatorial synthesis, ribosome display methods and by systematic evolution of ligands by exponential enrichment (SELEX).
They are selected from large combinatorial pools of sequences by Systematic Evolution of Ligands by Exponential Enrichment (SELEX) for their capacity to bind to targets, which can range from small molecules to proteins or polysaccharides, as well as tumor cells [16] [19], [21] [23].
Aptamers are short single-stranded nucleic acid ligands (DNA or RNA) and are usually generated by using an in vitro process referred to as SELEX (exponential evolution of ligands by systematic enrichment).
More generally, the data also demonstrate that cross-reactivity with various targets may be detected by systematic pair-wise similarity measurement of ligand-annotated binding sites.
In this study, we characterize the in vivo role of the Fe-S cluster binding domain in Pri2 function by systematic site-directed mutagenesis of the putative cysteine ligands.
Despite the numerous methods described for measuring 3-D similarities between protein-ligand binding sites [37], there are still very few reports of predictive target identifications by systematic binding site comparisons (for a recent review see [38]).
In this study, we have constructed multiple mutated MIEPs by changing the natural κBs in the human MIEP into the high-affinity artificial sequences that were in vitro selected by using systematic evolution of ligands by exponential enrichment (SELEX) and predicted by bioinformatics.
Aptamers comprise a novel class of highly specific bio-recognition elements which are produced by SELEX (systematic evolution of ligands by exponential enrichment) process.
