Flexible Monitoring of Small Molecules in Complex Matrices with Aptamer Affinity Reagents using Bio-Layer Interferometry
December 5th, 2018 – 8am PST
The Aptamer Group is pleased to work with Pall ForteBio on this informative webinar. Aptamer Group uses Bio-Layer Interferometry (BLI) to screen and characterize the interactions of aptamers with their respective targets. The Octet® and BLItz® platforms help develop assays and give proof of concept data for the use of aptamers in other applications; like protein purification or small molecule-protein diagnostic applications.
By taking advantage of the conformational change in the aptamers upon target binding, the Octet system was implemented for high-throughput screening and characterization of aptamers against small molecule targets (~300Da). The resulting aptamers can, in turn, be used for screening samples for the presence of the target small molecule compound.
This webinar will present data to show the versatility of the BLI platforms with example data from Optimers™ for different aptamer based applications, with a focus on small molecule detection and quantification.

The award recognises, identifies and honours the most respected companies and their C-level executives operating within the United Kingdom today.
An aptamer based assay is presented for the determination of the antibiotics oxytetracycline (OTC) and kanamycin (KAN). Magnetic beads were applied for separation, and gold nanoparticles (AuNPs) for signal amplification.
Sandwich pair of aptamers but also antibody/aptamer pairs that increased sensitivity by 3 orders of magnitude in buffer and serum.
