DAPI single band Fluorescence Filter Set
DAPI single band Fluorescence Filter Set
DAPI (4′,6-diamidino-2-phenylindole) is a blue-fluorescent DNA stain that binds strongly to A-T rich regions in DNA. As DAPI can pass through an intact cell membrane, it is commonly used as a nuclear counterstain in fluorescence microscopy, flow cytometry, and chromosome staining.
FITC single band Fluorescence Filter Set
FITC Fluorescence Filter Set
Fluorescein isothiocyanate (FITC) is the original fluorescein molecule functionalized with an isothiocyanate reactive group (-N=C=S), replacing a hydrogen atom on the bottom ring of the structure. It is the most common fluorescent reagents for biological research because of their high absorptivity, excellent fluorescence quantum yield, and good water solubility.FITC has excitation and emission spectrum peak wavelengths of approximately 495 nm/519 nm.
