Rainbow Seed Fund Invests in AgPlus Diagnostics

Rainbow Seed Fund, an early-stage venture capital fund focused on promising technologies developed at the UK’s largest publicly funded research facilities and campuses, today announces its investment into AgPlus Diagnostics, a technology platform developed by scientists at the UK’s National Physical Laboratory (NPL).

AgPlus’ diagnostic platform technology has the potential to make rapid, accurate, costeffective diagnostic testing – without the need for laboratory facilities – a reality in the areas of human and animal health, sports medicine and environmental testing. The platform is based on research conducted at Rainbow partner NPL, the UK’s National Measurement Institute, a world-leading centre in developing and applying the most accurate measurement standards available.

The AgPlus analytical platform utilities electrochemical immunoassay technology in a patented microfluidic cartridge format. The unique electrochemical signalling and measurement system allows extremely sensitive, accurate and quantifiable results to be obtained from a very small sample volume (50µl) in under 10 minutes.

This capability, demonstrated with a range of commercial partners, brings users the functionality, accuracy and precision of a laboratory analyser, into the palm of their hand. AgPlus’ technology platform can be used near-patient or in-field, critically where faster results give users the ability to make decisions with confidence – in minutes, not hours or days. The system gives rapid, laboratory-grade sensitivity and specificity, within a handheld device on a range of sample types.

About AgPlus Diagnostics Ltd.

AgPlus was established in 2011 to commercialise patented technology for an ultra sensitive, quantitative, electrochemical immunoassay platform originally developed within the UK Government’s National Physical Laboratory. This novel platform has significant potential to improve and enhance diagnostic tests currently used in point-of-care and other resource-limited settings. It is targeted at satisfying market demands for diagnostic testing in human, veterinary and industrial sectors. AgPlus Diagnostics is based at Colworth Science Park in Sharnbrook, Bedfordshire.

About Rainbow Seed Fund

The Rainbow Seed Fund is an early-stage venture capital fund dedicated to kick-starting technology companies from great science. We focus on companies based on research conducted in publicly-funded laboratories, located on the Research Councils’ science and technology campuses or working in fields of strategic interest to the UK (such as synthetic biology). The Fund is backed by nine UK publicly-funded research organisations including STFC, BBSRC, Dstl and NERC and the Department of Business, Innovation and Skills (BIS). The Fund, whose portfolio comprises more than 30 companies, holds investments in some of the UK’s most innovative companies in areas as diverse as novel antibiotics, research into Alzheimer’s disease, “green” chemicals and airport security. The Fund has leveraged more than £190 million of private investment from just under £9 million of its own investment and helped create many high-value technology jobs
