然后是碱性荧光染料，造纸厂用来增加纸的亮度。
直接和分散的荧光黄，印染厂用来增加棉质和化纤面料的艳度

碘化丙啶(propiolium iodide,PI)能嵌入DNA双螺旋中,可使荧光强度增加约20倍,以488nm波长激发,DNA/PI复合物最大的发射波长约为615nm.
1.小鼠Lewis肺癌细胞DNA含量测定方法
(1).从C57BL/6小鼠上切除肿块,在培养皿内用PBS冲洗.
(2).去除结缔组织及脂肪,剪碎肿块.
(3).小碎片移入1.20×38mm注射针,加压使其通过,于4℃条件下重悬细胞于HBSS中.
(4).将200～300μL细胞悬液(5×105细胞/mL)中加入3mL PI(50μg/mL),染色3LL细胞,于4℃存放20～30分钟.
(5).测定580～750nm之间的发射荧光,以去除末结合PI产生的激发光与发射光谱线之间的重叠部分.
是欢快活泼的光辉色彩，是暖色系中最温暖的色，它使人联想到金色的秋天，丰硕的果实；
是一种富足、快乐而幸福的颜色。让人感觉成一种稳重、含蓄又明快的温暖；
橙色也会带来一种甜甜的感觉。
