LUCIFERIN

虫荧光素 luciferin

  　　亦称发光素。是作为化学发光的生物发光物质，为供作虫荧光素酶催化作用的底物的物质之总称。在发光组织和发光细菌的热水抽出物中含有每种生物特有的一些耐热性低分子成分。耐热性成分在两种以上时，其发光所必需的起直接化学变化的物质一般称为虫荧光素。在发光细菌中，黄素单核苷酸（ FMN）必须和长链饱和醛共同存在，前者被认为是虫荧光素。此外也有靠虫荧光素和虫荧光素酶那种酶一底物系统以外的系统产生生物发光的。  

In Vivo Luciferin Imaging Procedure

  Mice are injected by an intraperitoneal route with a Luciferin solution (15 mg/mL or 30 mg/kg, in PBS, dose of 150 mg/kg) that is allowed to distribute in awake animals for about 5-15 minutes. The mice are placed into a clear Plexiglas
