Fitc photobleaching
WebFITC (Ex max 494 nm/Em max 520 nm) Fluorescein isothiocyanate (FITC) is a fluorochrome with a molecular weight of 389 Da. FITC is sensitive to pH changes and photobleaching. Due to nearly identical excitation and emission properties, FITC and Alexa Fluor® 488 cannot be used simultaneously. FITC is relatively dim and should be reserved for highly WebPhotobleaching becomes an issue when fluorescence levels decrease so far that the signalnoise ratio is also decreased [e.g., for FITC conjugated to ANM (mouse anti-human nestin monoclonal antibody ...

WebAlthough FITC is still the most popular fluorescent labeling dye for preparing green fluorescent bioconjugates, there are certain limitations with FITC, such as severe photobleaching for microscope imaging and pH-sensitive fluorescence. Protein conjugates prepared with FITC-xtra are far superior compared to the corresponding FITC conjugates. WebFITC conjugates are not very stable to elevated temperatures and are very pH sensitive (in terms of their fluoresence behavior; fluoresence yield was found to be higher at pH 7.4 than at pH 6.0 by ...
WebElectrospun nanofibrous structures provide good performance to scaffolds in tissue engineering. We measured the local diffusion coefficients of 3-kDa FITC-dextran in line patterns of electrospun nanofibrous structures fabricated by the direct-write electrospinning (DWES) technique using the fluorescence recovery after photobleaching (FRAP) … WebFITC is a fluorescein derivative consisting of a fluorescein core and an amine-reactive isothiocyanate moiety. The isothiocyanate group reacts with primary amines forming …
