Fluorescein

Fluorescein dyes are a type of optical probe with fluorescein as the parent core, which have good water solubility, low cytotoxicity and high photostability. Their excitation and emission wavelengths are mainly concentrated in the visible light region and are widely used in the fields of biomarkers, cell imaging and immunoassay. In addition, chemical modification can achieve highly specific labeling and detection of specific biomolecules.

FITC
T152843326-32-7
FITC is a green fluorescein derivative. FITC is often used to label biological macromolecules such as antibodies and proteins. FITC can also be used to label nucleic acids. FITC can be used as a fluorescent probe to detect cell viability, cell apoptosis, etc. FITC showed a maximum excitation wavelength of 494 nm and yellow-green fluorescence at a maximum emission wavelength of 520 nm.
