Lateral Flow Assay Products

The lateral flow immunoassay test, also known as immunochromatography assay, or strip test is an extremely versatile and fast method for visual detection of antigen in a sample. Lateral flow immunoassays are essentially immunoassays adapted to operate along a single axis to suit the test strip format but can also be operated in a vertical flow format.

The probes used in lateral flow and other similar assays such as vertical flow are commonly based on gold nanoparticle antibody conjugates. Due to the optical properties of noble metal nanoparticles such as gold, detection with the naked eye can be achieved with excellent sensitivity. The assay can also be adapted to run both in non-competitive and competitive mode.
