FITC
異硫氰酸熒光素 (fluorescein isothiocyanate, FITC) FITC純品為黃色或橙黃色結(jié)晶粉末，易溶于水和酒精溶劑。有兩種異構(gòu)體，其中異構(gòu)體Ⅰ型在效率、穩(wěn)定性與蛋白質(zhì)結(jié)合力等方面都更優(yōu)良。FITC分子量為389.4，*大吸收光波長為490～495nm，*大發(fā)射光波長為520～530nm，呈現(xiàn)明亮的黃綠色熒光。FITC在冷暗干燥處可保存多年，是目前應用*廣泛的熒光素。其主要優(yōu)點是人眼對黃綠色較為敏感，通常切片標本中的綠色熒光少于紅色。Sigma相關產(chǎn)品資料：
