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 […]

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 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 […]

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 […]

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 […]

  • 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 […]

  • The actions for possible aptamer based Western Blot.

Aptamer Applications: Western Blotting

25th July, 2017
AptaBlot – increasing the utility of Western Blotting
Western Blotting is a powerful technique used to detect and identify proteins. Antibodies have traditionally been used as the detection molecule, but aptamers are now emerging to complement or address shortfalls of existing reagents.
Basis of the Western Blot
The first step of a Western blot uses electrophoresis […]

Affinity Reagents and Reproducibility

01 July 2016

There is a current crisis in the life sciences. Reproducibility of results is at a reported all time low, with only 18% of data able to be verified by independent groups (Baker, 2015). As a consequence, the National Institute of Health (NIH) has urged the scientific community to discover new ways to increase […]
