Abstract: 比较了在OP50-NGM、JM109-NGM、OP50-LB、JM109-LB四种不同培养基上秀丽隐杆线虫的生长效果;测定了在三种温度和含不同甘油浓度冻存液中的虫体保存效果。结果显示,秀丽隐杆线虫在OP50-NGM培养基中生长良好,在JM109-LB培养基中生长较差。在-80℃最佳温度条件下,秀丽隐杆线虫在含50mL/L甘油的LB培养基中的存活率达78%;在含50mL/L甘油的PBS中的存活率达52%;而在含100mL/L甘油的水溶液中的存活率仅为8%。用液氮保存,成虫和幼虫均可存活;而在-80℃和-20℃条件下,仅有幼虫存活。结果表明,秀丽隐杆线虫在OP50-NGM培养基中培养发育生长较好;在-80℃条件下,含50mL/L甘油的LB培养基适于保存秀丽隐杆线虫。
