Performance of Estapor Red Intense Microspheres
15 Aug 2023In this application note, Merck explores the development of next-generation lateral flow tests (LFTs) requiring high sensitivity, user-friendliness, and cost-effectiveness. Intense-colored microspheres are focal for sensitive detection, offering advantages like strong signal intensity, readability at low concentrations, stable conjugation, reproducibility, and cost-effectiveness. LFTs gained traction, especially during COVID-19, fostering demand for advanced designs. Merck's Estapor® team introduces microspheres such as Estapor K1-030 and K1-040 Red Intense, sized at 300 nm and 400 nm. A comparison in an HBsAg antigen assay showcases their applicative performance.
