1.涂布200ul(15cm) 或者100ul(10cm) X-α-gal 贮液于预制平板上。
2. 放于37 oC培养箱至液体被吸收(约4小时)。
3. 将转化细菌或酵母涂于平板上并于合适温度培养至蓝色菌落出现。 1. 将已灭菌琼脂培养基冷却至55-50 oC。
2. 在已冷却的培养基中加入20 mg/ ml X-α-Gal贮液,混匀,快速倒平板。 1. Aho S., Arffman A., Pummi T., Uitto J., A novel reporter gene MEL1 for the yeast two-hybrid system. Anal Biochem. 1997. 253, 270-2.
2. Chevalier P., et al., X-α-Gal-base medium for simultaneous enumeration of bifidobacteria and lactic acid bacteria in milk. J. Microbiol. Methods. 1991. 13, 75.
