GFP monoclonal antibody can improve the sensitivity of the GFP detection and expand the application of GFP. The GFP mAbs could be very useful in the location of the antigen, purification of fusion protein, interaction between host and pathogen and the development of new detection reagent. GFP单克隆抗体可扩大GFP检测的灵敏度,拓展GFP的应用范围,预计GFP单抗在抗原定位、融合蛋白纯化、病原体与宿主之间相互作用研究以及新型诊断试剂研制等方面具有重要用途。
