Fitc labeling protein
WebFITC (fluorescein isothiocyanate) conjugated with dextran has a molecular weight of 4000–40,000 Da and, for sodium fluorescein, the molecular weight is around 376 Da ( Wilhelm et al., 2011 ). Both of these compounds show fluorescence and are hydrophilic in nature; the excitation wavelength is between 490 and 520 nm. WebComparison of the relative fluorescence of goat anti–mouse IgG antibody conjugates prepared from Alexa Fluor 488 dye and from fluorescein isothiocyanate (FITC). Conjugate fluorescence is determined by measuring the fluorescence quantum yield of the conjugated dye relative to that of a reference dye and multiplying by the dye:protein labeling ...
