Description

虫荧光素酶稳定剂
  
技术领域
本发明涉及一种酶稳定剂,特别是涉及一种虫荧光素酶稳定剂。
背景技术
生物发光是在自然界广泛存在的、有生命的生物产生的一种发光现象。发光的生物种类有很多,包括发光细菌、发光萤火虫、发光鱼、发光海星、发光甲虫等。而能催化荧光素或脂肪醛氧化产生生物发光的一类酶即为荧光素酶。人们从20世纪50年代就已经开始了对荧光素酶的研究。应用荧光素酶大大增加了生物发光免疫分析技术的灵敏度和应用范围,并且由于荧光素酶具有敏感性高,特异性好,反应迅速,操作简单,应用范围广等特点,已普遍应用在医学、生物学、环境科学等领域。
虫荧光素酶能有效的催化由三磷酸腺苷(ATP)、荧光素、氧气组成的反应,将生物能转变成光能发出荧光。虫荧光素酶生物发光技术在食品,医学,农业,生命科学等领域有广阔的应用前景。但虫荧光素酶对温度及冻融等因素极为敏感,使用时需分装保存在-18℃冰箱中,否则极易失活。虫荧光素酶的酶活不稳定性,较大的影响了其开发应用。急需一种虫荧光素酶稳定剂,为虫荧光素酶的大规模应用扫除障碍。
发明内容
本发明所要解决的技术问题是,克服以上现有技术的缺点:提供一种有效提高虫荧光素酶稳定性,延长其保存时间的虫荧光素酶稳定剂。
本发明的技术解决方案如下:一种虫荧光素酶稳定剂,它包括以下组分:甘油100-250g/L,甘氨酸0.08-0.12mol/L,溶剂为双蒸水。
作为优化,它还包括聚乙二醇8-16mmol/L和/或蔗糖40-60mmol/L。
即它包括以下组分:甘油100-250g/L,甘氨酸0.08-0.12mol/L,聚乙二醇8-16mmol/L,溶剂为双蒸水。
或包括以下组分:甘油100-250g/L,甘氨酸0.08-0.12mol/L,蔗糖40-60mmol/L,溶剂为双蒸水。
或包括以下组分:甘油100-250g/L,甘氨酸0.08-0.12mol/L,聚乙二醇8-16mmol/L,蔗糖40-60mmol/L,溶剂为双蒸水。
作为优化,所述甘油为200g/L。
作为优化,所述甘氨酸为0.1mol/L。
所述聚乙二醇为10mmol/L。
所述蔗糖为50mmol/L。
本发明的有益效果是:本发明的虫荧光素酶稳定剂对虫荧光素酶的活性有保护作用,降低虫荧光素酶对温度及冻融等因素的敏感度,使虫荧光素酶在使用时只需分装保存在4℃的冰箱中即可,有效提高了虫荧光素酶的稳定性,延长了保存时间,使用更为方便快捷。
