是一种碱性染料。通常用其酸性硫酸盐,溶于水、醇，显绿色。制法：在盐酸或硫酸介质中，苯甲醛与N,N-二乙基苯胺缩合，产物经氧化，并转化为硫酸盐。快绿用于IEF、PAGE 和 SDS-PAGE中的蛋白质染色。快绿染色比亮蓝R（Brilliant Blue R ）覆盖更宽范围的蛋白质浓度，是线性的。 电泳过后，把蛋白质固定在胶上染色更加灵敏，在胶上用0.1%快绿溶于30% (v/v) 乙醇、10% (v/v) 醋酸或7% 醋酸染色2小时再用30% (v/v) 乙醇、10% (v/v) 乙酸或 7% 醋酸去染色. 染色胶能在 625 nm浏览。检测灵敏度要比亮蓝R（Brilliant Blue R）高30% 另外，快绿还用于亚硫酸盐测定，制造细菌培养基，用以鉴别大肠杆菌及其他乳糖发酵菌，培养分离粪便中的伤寒杆菌。

Fast Green FCF has been a widely utilized tissue and protein stain used in IEF and SDS-PAGE. Has the ability to determine efficiency of transfer and localization of sample proteins on blotting membranes. Other applications of Fast Green FCF include using its clastogenic properties and it may also act at a presynaptic locus inhibiting neurotransmitter release in whole-cell voltage clamped hippocampal interneurons. Has been shown to be a beneficial stain to detail integumental injuries in Chinook salmon. When bound to protein, Fast Green FCF fluoresces near infrared; color index #42053.
