Use of a DNA aptamer to replace monoclonal antibodies in an impedance biosensor that uses microfluidics and a microelectrode for detection of the target molecule, in this case, the H5N1 subtype of avian influenza virus. Aptamer secondary structures and delta G were calculated using the free IDT online UNAFold and OligoAnalyzer programs. Biotinylated aptamers were synthesized by IDT with biotin conjugated at the 5′ end.

Description of a new aptamer selection platform that uses fixed-region blocking elements to ensure library diversity and guard against amplification artifacts. Truncated (random-region sequence only) and full-length library versions of aptamers were synthesized and HPLC-purified by IDT.

Jacobson O, Yan X, et al. (2015) PET imaging of tenascin-C with a radiolabeled single-strand DNA aptamer. J Nucl Med, 56 : 616–621.

Development of the first agent for imaging and quantifying the cancer associated protein, tenascin-C—a tenascin-C-specific single-stranded DNA aptamer. The aptamer was radiolabeled with 18F and 64Cu and used in PET-imaging studies to measure tumor uptake and metabolism. All aptamers, including FITC-aptamers, were synthesized by IDT.

xGen Lockdown Probes were used to rescue drop-out regions of SureSelect® probe panels (Agilent), giving more uniform target coverage. The probes were able to target 29 genes from whole blood genomic DNA, isolated from over 1000 patients.
