Webthe fluorescein can be easily detected on a standard transilluminator without staining. As illustrated in Figure 1, the DNA integrity (covalently closed circular form of the plasmid) is not altered by the attachment of the fluorescein tags. The desired density of fluorescein tags on the resultant 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 …
