Rapid small molecules detection using our aptamer-based displacement approach

The challenge
Small molecules such as antibiotics, drugs, toxins and food additives are often perceived as difficult targets to obtain a suitable affinity ligand. The development of rapid, cost-effective, single-step assays for the sensitive and specific detection of small molecules are very attractive for many applications ranging from life sciences to environmental analysis. Unfortunately, current […]

Aptamers based ELISA for virus detection – A strong potential in combatting COVID-19 battle

27th April 2020
Currently, viral infection is a serious threat for human beings. The world is facing a global pandemic associated with the COVID-19 virus, for which virulence and infectious dose data are still emerging. With almost 3,025,732 confirmed cases of COVID-19 worldwide and 209,001 deaths as of 27th April 2020 as per WHO, accurate and […]

Small Molecule IVD

23rd July 2019
Aptamer based ‘gain of signal’ assay for small molecule detection

Detecting small molecules represents a challenge for In vitro diagnostics (IVD) due to sensitivity and specificity limits of many detection methods. Our specially designed displacement approach allows us to select aptamers that can readily be used in various IVD and point of care (POC) […]

Small molecules detection with aptamer based BLI and ELISA-like assays

2nd July 2019
Detecting and quantifying small molecule analytes can be difficult. Our specially designed displacement approach allows us to select aptamers which can directly be used in various biosensor platforms for the detection of small molecules. Binding of the aptamer to the analyte gives a ‘signal amplification’ effect which can be used as a basis for small […]

Aptamers excel as binding reagents in ELISA replacement assays for antibiotics in complex media such as plasma, milk and others

18th May 2018.

Traditionally small molecules, such as antibiotics, have been difficult targets for ELISA development. Aptamer Group has selected aptamers that bind to small molecules, previously inaccessible to other binding technologies. Utilising our state-of-the-art automation and parallel processing techniques, we can select high affinity and highly specific aptamers against small molecule targets, in solution. These […]
