Lumiprobe熒光素的替代染料–菁染料
知識背景：
菁染料是性能優良的可代替熒光素的染料，摩爾吸光系數高，其琥珀酰亞胺酯是最常用的脂肪氨基標記試劑，廣泛用于蛋白、抗體、核酸及其他生物分子的標記和檢測。通過改變次甲基鏈的長度, 可改變其熒光發射波長，每增加一個雙鍵，按照Huoffman 規則正好紅移約100nm。
菁染料Cy3 和Cy5 已成為基因芯片的首選熒光標記物; 另外,Cy5, Cy5.5 和Cy7 的吸收在近紅外區背景非常低，是熒光強度最高、最穩定的長波長染料。特別適合于活體小動物體內成像代替放射性元素。
但由于菁染料, 尤其是不對稱菁染料的合成副反應多, 副產物極性相近, 產物的分離提純相當困難。菁染料特別是水溶性菁染料分子極性大, 分離提純越加困難。
應用領域：
?廣泛應用于多肽，蛋白，核苷酸及其他生物分子的標記和檢測。
