異硫氰酸熒光素可以把細(xì)胞染色嗎

異硫氰酸熒光素可以使細(xì)胞內(nèi)的蛋白質(zhì)著色進(jìn)而把細(xì)胞染色。

異硫氰酸熒光素是生化試劑,也是醫(yī)學(xué)診斷藥物,主要用于熒光抗體技術(shù)中的熒光染料,能和各種抗體蛋白結(jié)合,結(jié)合后的抗體不喪失與一定抗原結(jié)合的特異性,并在堿性溶液中具有強(qiáng)烈的綠色熒光。用于醫(yī)學(xué),農(nóng)學(xué)和畜牧等方面,可對(duì)由地細(xì)菌病毒和寄生蟲等所致疾病進(jìn)行快速診斷。

異硫氰酸熒光素(fluorescein isothiocyanate, FITC) FITC純品為**或橙**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，最大吸收光波長(zhǎng)為490～495nm，最大發(fā)射光波長(zhǎng)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(yīng)用最廣泛的熒光素。其主要優(yōu)點(diǎn)是人眼對(duì)黃綠色較為敏感，通常切片標(biāo)本中的綠色熒光少于紅色。
