異硫氰酸熒光素 (fluorescein isothiocyanate, FITC) FITC純品為黃色或橙黃色結晶粉末，易溶于水和酒精溶劑。有兩種異構體，其中異構體Ⅰ型在效率、穩定性與蛋白質結合力等方面都更優良。FITC分子量為389.4，zui大吸收光波長為490～495nm，zui大發射光波長為520～530nm，呈現明亮的黃綠色熒光。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。
Description
Application Reagent for the FITC labeling of proteins; Microsequencing of proteins and peptides (HPLC)
Biological applications include use as a fluorescent labeling reagent for proteins, a fluorescent reagent for protein tracing, and a reagent in the fluorescent antibody technique for the rapid identification of pathogens. FITC is yellow-orange in color with an absorption maximum at 495 nm. Upon excitation it emits a yellow-green color with an emission maximum at 525 nm.
