FITC (Fluorescein isothiocyanate) is a derivative of fluorescein. FITC exhibits an excitation maximum at λ = 495 nm and emission maximum at approximately λ = 519 nm. FITC can be easily used as labelling agent of various substrates such as proteins or polysaccharides. Isothiocyanate easily reacts with nucleophiles such as amines under mild conditions.  FITC can also be used in flow cytometry.

FITC（异硫氰酸荧光素）是荧光素的衍生物。 FITC 在 λ = 495 nm 处表现出最大激发，在大约 λ = 519 nm 处表现出最大发射。 FITC 可以很容易地用作各种底物如蛋白质或多糖的标记剂。 异硫氰酸酯在温和的条件下很容易与亲核试剂如胺反应。 FITC 也可用于流式细胞术。

Cibacron Blue 3G-A is an anionic anthraquinone dye. It is as a ligand in affinity chromatography for the purification of proteins, enzymes and biopolymers. Cibacron Blue 3G-A has also been employed in the textile industry for many years. It has shown tremendous protein binding capacity and can readily be immobilized on polymers containing a hydroxyl group.

Cibacron Blue 3G-A 是一种阴离子蒽醌染料。 它是亲和色谱中的配体，用于纯化蛋白质、酶和生物聚合物。 Cibacron Blue 3G-A 也已在纺织工业中使用多年。 它已显示出巨大的蛋白质结合能力，并且可以很容易地固定在含有羟基的聚合物上。
