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.

Lymph node cells taken 24 hr after skin-painting mice with the contact sensitizer fluorescein isothiocyanate (FITC) induce delayed-type hypersensitivity in recipient mice. Skin-painting increased the number of dendritic cells (DC) in the draining lymph nodes without significantly changing the number

Is the intensity of FITC (e.g., Product No. F7250) pH dependent?
1 answer-
Yes; many articles have reported the pH dependence of the fluorescence of fluorescein derivatives. See the following references: Archives Biochem. Biophys., 133, 263 (1969); J. Immunol., 95, 1165 (1966); Archives Biochem. Biophys., 73, 1 (1958); Standard test for labeling efficiency of FITC with BSA: NCCLS Approved Standard: ASM-1, 2nd ed., June, 1975; Characterization of FITC-dyes by IR and TLC: Analytical Biochem., 29, 526 (1969); Fluorescent labeling of proteins: Proc.

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.
