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 […]

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 […]

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 […]

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 […]

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, […]

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 […]

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 […]

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 […]

Previously we introduced aptamers as a tool for cell specific staining. Here we have taken this technology a step further to demonstrate that aptamers can monitor disease progression in cancer.
By utilising our selection methodology, we can rapidly isolate aptamers against cells in different disease states. Through this process we have been able to identify […]
