Biosensors developed using aptamers distinguish between closely related small molecules

4th May 2018

Development of biosensors for the detection of small molecules is notoriously difficult due to the lack of suitable antibodies and the relatively small signals, which result upon small molecule binding to them. At Aptamer Group we select aptamers that bind to small molecules with high specificity and undergo a substantial conformational change that gives […]

Cell Imaging – Aptamers can monitor the different stages of cancer

18th April 2018
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 […]

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 Group Update: Quarter 3

Message from the CEO
I am pleased to report that the trends mentioned in the last Newsletter continue to improve. We can now boast successful delivery of aptamers to a range of small and large molecule targets for customers in academia, biotech and big Pharma. We are also moving towards integration of aptamers into devices and […]

  • A diagram showing how ELISA has developed into ELISA

ELONA: the evolution of ELISA

5th September, 2017
At Aptamer Group we consider it vital to invest in the scientists of tomorrow. A great method for achieving this is by providing an environment where students can expand their knowledge. By having close ties with the University of York, Aptamer Group is able to support student industrial placements. One student who has […]

Aptamer Selection in Complex Media

25th August, 2017
Starting with the end in mind
The use of aptamers in point of care diagnostic devices, for monitoring drug dose levels or for use as therapeutics, requires functionality across a wide variety of conditions.

Aptamer selection starts in conditions optimised to promote aptamer/target interaction to identify the best target-binders. Subsequently, by introducing different pressures, we […]

  • 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 […]

  • Aptamer, Flow Cytometry, Data, Stain, Antibody Alternative

Aptamer Application: Flow Cytometry

1st August, 2017.
Flow Cytometry
Flow Cytometry is a technique used to identify biomarkers on cell surfaces and intracellular molecules. Most flow cytometers use fluorescently labelled antibodies to differentiate between cells expressing different markers.

Initially the cell sample is suspended, stained with a fluorescent label and washed to remove any non-specific binding. The suspension is introduced into the […]
