产品简介
中文名称 | GUS染色试剂盒 |
英文名称 | GUS Stain Kit |
储存条件 | -20℃,避光保存,有效期6个月。 |
规格 | 100ml |
单位 | 盒 |
GUS(β-Galactosidase)基因是存在于E.coli等一些细菌基因组内的编码β-葡萄糖苷酸酶的一种水解酶,该基因常作为融合标记用于植物转基因分析和调控研究中。GUS受体基因系统有表达E.coli GUS酶的稳定性和在植物内的低活性,绝大多数植物没有检测到葡萄糖苷酸酶的背景活性,以β-葡萄糖苷酸酯类物质为底物,其反应产物可用多种方法检测出来。5-Bromo-chloro-3-indolyl β-D-glucuronide,cyclohexylammonium salt(简称为X-Gluc或X-GlcA),是检测大肠杆菌中GUS基因的底物,可快速检测植物中GUS基因融合标记。
GUS染色液是β-葡萄糖苷酶基因染色试剂盒(β-Galactosidase Reporter Gene Staining Kit)的简称。GUS染色液染色原理是适宜的反应条件下,β-葡萄糖苷酶(GUS)可将X-Gluc水解成蓝色物质,该物质不溶解于转基因的细胞核组织中的靛蓝物质,具有GUS活性的部位或位点呈现蓝色或蓝色斑点,可用肉眼或显微镜观察到。GUS染色液可用于生物化学活性分析、免疫分析以及组织和细胞的组织化学染色,多用于转基因植物的GUS基因表达分析。该试剂仅用于科研领域,不适用于临床诊断或其他用途。
