Malaria is a serious life threatening disease, affecting a large portion of the population in developing countries. Over the last decade, there has been a continuous effort to develop efficient, stable, sensitive and low cost detection system for malaria. Currently, lateral flow based immuno-chromatographic tests are widely used for detection of malaria. However, […]

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 […]

Small molecules present an ongoing challenge for antibody production and detection. Development of biosensors for the detection of small molecules is difficult due to the lack of suitable antibodies and the relatively small signals. Tools to detect and quantify them are therefore in high demand.
At Aptamer Group we select aptamers that bind to […]

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 […]

Kanamycin is an aminoglycoside antibiotic isolated from Streptomyces kanamyceticus and is widely used to treat various infectious diseases in humans and animals. However, like other aminoglycoside antibiotics, kanamycin exhibits comparatively narrow safety margin as high doses can cause ototoxicity, nephrotoxicity and allergic reactions.
The current methods used for analysis for detecting kanamycin levels in […]

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 […]

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, […]

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 […]

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 […]

Introduction:
Changes in hormone levels can be key indicators to a variety of issues, examples include testosterone levels in general health and well being(1) and diagnosing Cushing’s disease involving the steroid cortisol (2). While these small molecules and others are well documented and their role in health and disease is becoming better understood, researchers […]
