说明：X-Gluc (5-bromo-4-chloro-3-indolyl-beta-D-glucuronic acid, cyclohexylammonium salt) is a substrate for beta-glucuronidase (GUS) which is encoded by gusA, a widely used reporter gene. Glucuronidase cleaves X-Gluc to produce colorless glucuronic acid and an intense blue precipitate of chloro-bromoindigo (see the scheme below).应用：Detection of GUS expression in plant cells and tissues (1).Detection of infections caused by E.coli.Detection of bacterial contamination in food and water samples.质量控制：Purity of ≥ 97% confirmed by HPLC.保存条件:Store at -20°C in the dark.注意：Preparation of a 0.1 M stock solution in dimethylformamide or dimethylsulfoxide is recommended.
