MaintenanceofProbesinbacteriaincludingEscherichiacoli
Plasmid (pUC series) containing genomic DNA fragments are maintained in E. coli strain DH5aTM. The E. coli cultures are routinely cultured at 37 C on Luria-Bertani (LB) agar on or in LB broth containing Ampicillin (30 µg/ml) or Carbenicillin (50 µg/ml broth, 100 µg/ml agar). E. coli strains are usually preserved in stab agar or glycerol for mid-term storage and lyophilized for long-term storage.Storage in Stab Agar: ......阅读全文

靛基质试验原理及照片示例
靛基质（Indole）试验：某些细菌能分解蛋白胨中的色氨酸，生成吲哚。吲哚的存在可用显色反应表现出来。吲哚与对二甲基氨基苯醛结合，形成玫瑰吲哚，为红色化合物。试验方法：将待试纯培养物小量接种于试验培养基管，于36±1C培养24h时后，取约2ml培养液，加入Kovacs氏试剂2~3滴，轻摇试管，呈红色
