Aptamer based assay for sensitive detection of antibiotics in food and water samples

Antibiotics have been widely used in human medicine, aquaculture and agriculture to treat serious infectious diseases. However, overuse and misuse of antibiotics in some areas have contributed to the residues of antibiotic contaminants in water bodies and food products such as meat and dairy. This misuse has resulted in generation of super bacteria with tolerance […]

Applications of aptamers as GPCR targeting drugs

The current wave of COVID-19 infections around the globe has resulted from a novel coronavirus employing its spike glycoprotein to bind with the protein binding sites of the host cells. These virus particles have the notorious tendency to proteolytically generate mutated biologically active fragments involved in signal transduction pathway resulting in the proliferation and transmission […]

Aptamer Stability

29th August 2018
At Aptamer Group, every custom aptamer project begins with a feasibility study. The target and assay matrix are tested for compatibility and stability with the aptamer library, under a variety of conditions. At this early stage it is important to understand the optimal strategy for the selection, address any potential issues and […]

Portable Aptamer Based Sensor for Toxin Detection

9th August 2018 
Aptamers continue to demonstrate advantages in platforms and applications which require specific detection of small molecule targets.
There has been a growth in the use of point of care devices across a range of applications and assay types due to a need for rapid and reliable analysis (Vashist 2017). Aptamers are perfectly suited for […]

Aptamer-based Lab on chip for the rapid detection of food-borne pathogens

1st August 2018
Scientists from the Technical University of Denmark, led by  Krishna  Kant have published a new review in Biotechnology Advances including  aptamer-based approaches  for the rapid detection of food-borne pathogens.
Food borne diseases, caused by the consumption of foods contaminated with pathogens or their toxins, are one of the major burdens to public health, causing […]

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 […]

Cell specific staining

Cell specific staining in Confocal Imaging
Over the next few weeks we are going to look at examples of where we have developed aptamers for cell imaging.

One of the most common methods for understanding the structure and function of biological systems is through confocal microscopy. Cell imaging technologies have been advancing at a rapid pace, however […]

Aptamer Applications: Using Aptamers in Lateral Flow Assays
There is a growing need for easy to use, point of care tests. A technology where aptamers can be used to achieve this is in lateral flow assays. A lateral flow assay is a method of detecting the presence (or absence) of an analyte without complicated […]

  • Comparing healthy to disease state cells using aptamers

Aptamer Application: Biomarker Discovery

22nd August, 2017.
Biomarker Discovery

A biomarker is a measurable indicator showing the presence or severity of a disease state. Using biomarkers to differentiate between healthy and diseased cells can enable the development of specific diagnostics, research tools and targeted therapeutics.

Biomarker Discovery using Aptamers

Traditional biomarker discovery is a long process and relies on multiple comparisons using various […]
