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 […]

Biomarker detection in serum becomes easier using aptamer based biosensor

30th July

Blood contains a range of protein biomarkers that could be used in the early detection of disease. One important biomarker is human epidermal growth factor receptor 2 (HER2) which is overexpressed in the most common breast cancer. Various HER2 detection techniques have been reported, including FISH or IHC based assays, however, these techniques require […]

Literature Review: Distinguishing glycosylation patterns in proteins for the early detection of cancer.

7th May 2019
Glycosylation is a post-translational modification where a carbohydrate is added to a protein. Glycosylation of proteins serves a number of functions in a cell, including: improve protein folding, forming lipid anchors and cell-to-cell adhesion. While glycosylation of a protein can be vital for its function, any changes in the position or number of […]

The Reusability of Aptamers for Affinity Chromatography

23rd April 2019
We have often shown that aptamers make ideal ‘capture reagents’ for use in target specific affinity chromatography. Their flexible structure makes aptamers ideally suited for the specific binding and controlled release of their target, even in the presence of complex matrixes such as cell lysates or plasma.

During the aptamer selection process, we can […]

Literature Review: Distinguishing closely-related amyloid precursors using an RNA aptamer

16 April 2019
Amyloid fibrils are misfolded proteins which have assembled to form insoluble aggregates in the form of fibers that are resistant to degradation. Amyloid formation is often associated with a disease that is specific to the proteins or localisation of the aggregate. Well known examples of amyloid diseases include Alzheimer’s disease, Diabetes type 2 […]

Aptamers to discriminate between proteins with Post Translation Modifications

2nd April 2019
Background:

Post Translational Modifications (PTM) are biochemical variations of cetain amino acids made to a protein after biosynthesis. These modifications diversify the proteome and play a fundamental role in regulation and targeting of proteins, their interactions with other molecules, as well as their structure, activity and function. Common types of post-translational modifications include phosphorylation, […]

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 […]

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 […]
