TGR BioSciences Pty Ltd (TGR) is pleased to announce the award of patent protection for a faster and more sensitive immunoassay. The assay has a wide range of potential applications, from clinical diagnostics to the detection of plant diseases.

TGR’s CaptSure™ technology was granted a US Patent (9,086,407) on 21 July 2015, giving TGR exclusive rights to licence the technology to researchers and manufacturers around the world.

Director of TGR, Dr Michael Crouch, said that CaptSure™ technology improves the performance of standard immunoassays by providing a shorter incubation period without compromising sensitivity or quality.

“CaptSure™ improves both the speed and accuracy of these immunoassays by reducing the number of steps required to carry out a test — this results in less interference when measuring complex samples,” he said.

As opposed to conventional multi-incubation and multi-wash immunoassays, TGR’s CaptSure™ technology format requires only a single incubation and wash step — made possible by incubating the sample with both ‘capture’ and ‘detector’ antibodies at the same time. This reduces the overall assay time significantly compared to conventional assays.

In addition, the CaptSure™ technology also greatly reduces the costs of manufacturing these tests, by simplifying test development as well as reducing the amount of core reagents required.

The award of this new patent means TGR can now broaden its partnerships with other bio-manufacturing companies and laboratories to expand the use of CaptSure™ technology.


TGR BioSciences Pty Ltd (TGR) is pleased to announce a license agreement with one of the largest biological resource centers in the world, the Leibniz Institute DSMZ.

With a major focus on plant virus resistance and diagnostics, particularly in an agricultural setting, its license with TGR BioSciences will provide DSMZ with non-exclusive access to TGR’s CaptSure™ technology for use in plant virus immunoassays.

Based in Braunschweig, Germany, DSMZ is not only Europe’s most comprehensive bio-resource center, with a collection of almost 40,000 items from human and animal cell lines to plant cell lines and viruses, it is also a state-of-the-art research institute.

Under the agreement, TGR will also provide antibody conjugation services, allowing DSMZ to access TGR’s proprietary antibody tagging and immobilisation technology.

Anne Hinton, CEO of TGR BioSciences, said that the license agreement shows the breadth of interest in TGR’s CaptSure™ technology, due to its broad application across a number of research fields.

“The use of CaptSure™ technology for virus detection in the agricultural sector provides unequivocal evidence of the broad utility of this immunoassay,” Ms Hinton said. “We are very pleased to be working with DSMZ in this important application.”

In comparison to conventional assays, which usually involve three separate incubations over 4-6 hours, CaptSure™ assays require only a single incubation period and can be performed within an hour, without compromising sensitivity or quality.

CaptSure™ technology also greatly reduces the costs of manufacturing these tests, by simplifying development and the amount of core ingredients required — making it the new gold standard for immunoassay technology development around the world.

Dr Wulf Menzel, Group Leader, Plant Virus Department at DSMZ said that after extensive testing, CaptSure™ technology was by far the most efficient immunoassay for their applications.

“We have extensively tested TGR’s CaptSure™ technology for our application in detecting several plant viruses,” Dr Menzel said.

“It has allowed us to produce assays with significant acceleration in speed, enabling efficient manufacturing for the development of kits for our large client base.

“We look forward to working closely with TGR in the future as we expand our assay base with CaptSure™ technology – we are planning to offer this new technology soon to the plant virus diagnostics sector under the name B-Fast ELISA”.

Innova Biosciences and TGR BioSciences Announce Co-Marketing Agreement for Core Technologies

Combining Innova’s Lightning-Link® conjugation kits with TGR’s CaptSure™ ELISA technology simplifies ELISA development and improves sensitivity.

Cambridge, UK and Adelaide, Australia, 16 January 2014: TGR BioSciences Pty Ltd (TGR), a life sciences company focused on the development of rapid, high sensitivity ELISA systems using their CaptSure technology, and Innova Biosciences (Innova), a specialist provider of bioconjugation systems, announced that they have entered into an agreement to promote and co-market each other’s highly complementary technologies, providing customers with a major step forward in simplifying the ELISA development process, while improving sensitivity and reducing costs.

TGR has determined that combining Innova’s Lightning-Link conjugation kits for the horseradish peroxidase (HRP) labelling of antibodies with its CaptSure technology in the development of ELISA systems maximises assay sensitivity, whilst enabling the development of a wide range of ELISA assays rapidly and cost effectively. As part of the agreement Innova customers will be introduced to the CaptSure technology, with the assurance that it will work alongside the Lightning-Link reagents. Similarly, TGR customers will receive a recommendation for Lightning-Link, with the knowledge that it will be available for licensing to them, should they choose to use it alongside CaptSure products.

TGR’s CaptSure technology simplifies ELISA assays to one-step procedures, making them much faster and easier to carry out. Both assay antibodies are added to analyte at once, and after a single wash step the HRP substrate is added to develop the signal. Importantly, costs of manufacture are greatly reduced, since only a single assay plate is required (coated with CaptSure reagent) rather than a different plate for each target, and the system also requires much less assay antibodies.

Innova’s Lightning-Link conjugation system provides the ability to label antibodies with only 30 seconds hands-on time, whilst offering 100% yields and enhanced sensitivity over traditional labelling techniques and over other conjugation systems on the market.
