In many bioscience applications, fluorescence-labeled proteins are used to analyze
cellular and biological functions. Here, fluorescein (FITC) and bovine serum albumin
(BSA) were used as model molecules. We tested the integration of a fluorescence
detector (FLD) into a semi-preparative FPLC system and evaluated the analysis of FITC
labeled BSA in comparison with classical UV/VIS detection. The use of a fluorescence
detector increases the sensitivity of the chromatographic analysis significantly.
