WebThe most common members of this group have been the tetramethylrhodamines—including the reactive isothiocyanate (TRITC) and carboxylic acid (TAMRA) derivatives—as well as the X-rhodamines. The X prefix of the X-rhodamines, ... fall between those of fluorescein and tetramethylrhodamine (Figure 1.6.3). With a peak absorption at ~520 nm, ... WebThe pH dependence of fluorescence of fluorescein isothiocyanate (FITC) conjugates could be described by a single proton dissociation (pK'a approximately 6.8). This allowed pH to be derived accurately from spectra using the simple Henderson-Hasslebach equation. FITC and TRITC conjugates were delivered to mouse macrophage lysosomes by pinocytosis. ears and head hurt
