Title

UTILIZING CELL-SELEX, AS A PROMISING STRATEGY TO ISOLATE SSDNA APTAMER PROBES FOR DETECTION OF STAPHYLOCOCCUS AUREUS

Pages

  633-638

Abstract

 STAPHYLOCOCCUS AUREUS is one of the most important pathogens in hospital acquired infections. Annually, many people are infected with S. aureus in hospitals.Rapid DETECTION of this bacterium is extremely helpful in preventing and managing this bacterium mediated diseases. APTAMERs are powerful probes, which can be used as a target explorer in a wide range of diagnostic systems. To isolate a specific APTAMER against S. aureus, a library of single-stranded DNA molecules was designed, and enriched through CELL-SELEX procedure. In the CELL-SELEX, the DNA library was exposed to the S. aureus bacterium in 8 reiterative quadruple rounds including: binding, separation, elution and amplification. After 8 rounds, the PCR product was cloned and sequenced. Cloned APTAMERic sequences were evaluated through enzyme-linked oligonucleotide assay (ELONA), and a sequence with the best outcomes was selected as ideal APTAMER. Eight rounds of CELL-SELEX procedure led to isolation of a specific ssDNA APTAMER against S. aureus and named as “STAPT” (conflation of STAphylococcus and APTAMER). Using ELONA technique, the DETECTION limit of this APTAMER was determined as 4×103 CFU/ml.The APTAMER “STAPT” showed the promising and potent abilities and features to be utilized as a bio-detection element likely in advanced DETECTION systems. Although more extended researches are needed for this purpose.
