品牌介绍

       活体体内光学成像(Optical in vivo Imaging)主要采用生物发光(Biolumininescence)与荧光(Fluorescence)两种技术标记细胞或者DNA,利用非常灵敏的光学 检测仪器,直接检测活体生物体内的细胞活动和基因行为。这项技术具有操作简单、所得结果直观、灵敏度高等特点,因为已经广泛应用于生命科学,医学研究以及药物开发等发面。该技术应用于植物研究方面,具体的应用领域包括:植物的突变体筛选、植物抗逆性状研究、离体细胞的基因表达、植物生理节律研究、植物发育研究、蛋白互作等。 

技术简介 

       Lumazone系统是美国Princeton Instrument(PI, Roper Technologies, Ins. 集团子公司)研制的活体生物发光系统,可以观察并成像将化学发光或者荧光标记后的动物、植物和微生物整体标本,并结合专业的数据分析软件,完成动物和植物体内基因表达的原位跟踪,药物筛选和药效检测,植物突变体检测和筛选,以及单细胞内的基因表达等研究。     

      在植物活体分子影像学的研究过程中,美国Roper公司最早参与其中,为科学家提供了高灵敏度的成像系统。1997年,朱健康教授在Plant Cell上发表的文章就已经使用Roper公司生产的高灵敏度 CCD。北京博益伟业仪器有限公司,作为 Roper Scientific公司在中国的代理,一直致力于将其最佳性能的光学成像系统推荐给客户,并凭借在生命科学研究领域多年来积累的经验,能够根据客户需求为客户量身定制成像系统,因此,已成为在此领域中具领先地位的系统供应商之一。
