BioPorto Diagnostics gRAD OneDetection strip

The generic Rapid Assay Device (gRAD) from BioPorto Diagnostics makes it easy and fast to develop a customised qualitative or semiquantitative lateral flow assay.

The gRAD OneDetection strip is an optimised generic lateral flow strip with a test line where a biotinylated capture antibody (or other biotinylated proteins) will bind, as well as a control line that will capture any antibody from mouse, rabbit and goat.

To generate a specific gRAD OneDetection test, just follow these simple steps: choose a target analyte to detect; find the most optimised matched antibody pair for this target; conjugate the capture antibody with biotin and the detection antibody with gold; and optimise the antibody solutions in the right concentrations.

When the sample of interest is added to the antibody solution, the antibodies react and can form a complex with the analyte in the sample. The mixture will — if a complex is formed — now contain both free capture antibody and an antigen-antibody complex with the analyte.

The strip enables users to create a custom lateral flow assay specific to their needs, as the product is not analyte dependent.
