WebFluorescent detection in lateral flow Related Antibody Conjugation Kits Detect the presence, or absence, of a target analyte in a sample with ease. Lateral flow assays, also known as … Fluorescein is a fluorophore commonly used in microscopy, in a type of dye laser as the gain medium, in forensics and serology to detect latent blood stains, and in dye tracing. Fluorescein has an absorption maximum at 494 nm and emission maximum of 512 nm (in water). The major derivatives are fluorescein isothiocyanate (FITC) and, in oligonucleotide synthesis, 6-FAM phosphoramidite. In cellular biology, the isothiocyanate derivative of fluorescein is often used to label and track cells in fluorescence …
