应用： 荧光素用作染色剂，通过共聚焦扫描激光显微镜（CSLM）定位小米淀粉表面的颗粒蛋白以及小米粉中的蛋白质。这一物质还用于对氨基苯甲酸光度测定。 非荧光试剂，在温和条件下易与氨基酸和肽中的伯胺反应形成稳定的高荧光化合物。由于水解，背景低。可用于氨基酸、蛋白质和蛋白水解酶的荧光测定。在蛋白质序列分析中有效阻断新产生的氨基末端。 A non-fluorescent reagent that reacts easily under mild conditions with primary amines in amino acids and peptides to form stable, highly fluorescent compounds. Low background due to hydrolysis. Useful in fluorometric assays of amino acids, protein, and proteolytic enzymes. Adequately blocks newly generated amino termini in protein sequence analyses. Fluorescamine reacts with primary amines in amino acids and peptides to form stable, highly fluorescent compounds. Useful for the fluorometric assay of amino acids, protein, and proteolytic enzymes. Effectively blocks newly generated amino termini in protein sequence analyses. Application： Fluorescamine has been used as a stain to localize granular proteins on the surface of foxtail millet starch as well as protein in foxtail millet flour through confocal scanning laser microscopy (CSLM). It has also been used for photometric determination of para-aminobenzoic acid. Non-fluorescent reagent that reacts readily under mild conditions with primary amines in amino acids and peptides to form stable, highly fluorescent compounds. Low background due to hydrolysis. Useful for the fluorometric assay of amino acids, protein, and proteolytic enzymes. Effectively blocks newly generated amino termini in protein sequence analyses.
