菌株E. coli HB2151 Cells 规格:100μL/管 状态:20%甘油保存 性质参数:K12 (lac-pro), ara, nalr, thi/F'[proAB, lacIq, lacZ M15]. 建议: 1. 菌株保存在20%甘油的培养基中,接到菌株后,请挑取菌液在2x YT-N平板(2xYT medium containing 100 μg/ml nalidixic acid)上划线,37℃过夜培养后,再次挑取单个菌落在Minimal Medium 平板上划线,37℃过夜培养后即可使用,以便使纤毛充分表达,利于噬菌体感染; 2. 在Minimal Medium 平板上生长的细菌,不宜在冰箱中放置过久再使用; 3. Minimal Medium plate 配制方法: Prepare stocks of the following: 1 M MgCl2•6H2O: Dissolve 20.33 g in distilled water to a final volume of 100 ml and autoclave. 1 M CaCl2•2H2O: Dissolve 14.7 g in distilled water to a final volume of 100 ml and autoclave. 1 M thiamine hydrochloride: Dissolve 33.73 g in distilled water to a final volume of 100 ml and sterilize using a 0.22 μm filter. 20% glucose: Dissolve 20 g of D-(+)-glucose (anhydrous) in distilled water to a final volume of 100 ml and sterilize by filtration through a 0.2 μm filter. Do not autoclave. In a 500 ml bottle, dissolve 6 g of Na2HPO4 (dibasic), 3 g of KH2PO4(monobasic) and 1 g of NH4Cl in distilled water to a final volume of 500 ml. adjust the pH to 7.4 with NaOH. In a separate 1 liter bottle, add distilled water to 15 g of Bacto-agar to a final Volume of 500 ml. Autoclave both bottles simultaneously to sterilize. Cool both bottles to 50-60°C and combine. Add1 ml of 1 M MgCl2•6H2O, 1 ml of 1 M CaCl2•2H2O, 1 ml of 1 M thiamine hydrochloride and 5 ml of 20% glucose. Pour plates immediately.
