FITC is not membrane permeable in healthy cells, it binds to surface proteins. Conjugates such as FITC-Dextran is an example of a more cell-permeable option.

Description générale
Fluorescein isothiocyanate (FITC) is yellow-orange in color with an absorption maximum at 495nm. Upon excitation, it emits a yellow-green color with an emission maximum at 525nm.
It is widely used to attach a fluorescent label to proteins via the amine group. The isothiocyanate group reacts with amino terminal and primary amines in proteins. It has been used for the labeling of proteins including antibodies and lectins.[1][2]
Fluorescein isothiocyanate isomer I has been proposed as a contact sensitizer.[3]

Application
Réactif pour le marquage FITC des protéines; le microséqueçage de protéines et de peptides (HPLC)
Reagent for the FITC labeling of proteins; microsequencing of proteins and peptides (HPLC)
Biological applications include use as a fluorescent labeling reagent for proteins[4][5][6], a fluorescent reagent for protein tracing, and a reagent in the fluorescent antibody technique for the rapid identification of pathogens. It may be employed as the derivatization reagent for amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine and P-phenylethylamine in human urine during their capillary electrophoretic (CE) determination. It may be used for the preparation of fluorescent antibodies. It was employed for in vitro sensitization studies.

After the FITC (e.g., Product No. F7250) is conjugated to the protein, what is the solution stability of the conjugated protein?
1 answer-
The stability of the conjugated protein will be essentially the stability of the unconjugated protein. Some conjugated proteins might be stable when stored at -20°C and other conjugated proteins will have better solution stability at 2-8°C If the protein concentration is too low, this also has a negative effect upon the stability of the conjugated protein.

How stable is FITC Isomer 1 (e.g., Product No. F7250) once conjugated to an antibody?
1 answer-
FITC can photo bleach fairly rapidly. The prepared solution should be stored in a dark container and protected from light. When viewing the antibody staining under a microscope, it is advisable to use subdued fluorescent light when possible. If the fluorescent light stays at one position for too long, photo bleaching is noticeable.
