Preparationofphageparticlesfromphagevectors
Pick up one phage vectors-containing colony with a sterile loop and put into 10 ml 2xTY + 10 µg/l tetracycline.Shake at 200 rpm and 37 °C untill the OD600~ 0.5.Dilute bacterial culture into 200 ml 2xTY + 10 µg/l tetracycline (dilution 1:20).Shake at 200 rpm and 30 °C approximately 20 hours.Centrifuge the bacterial culture (10000 rpm, 30 min, 4 °C) and transfer the supernatant into 50 ml Falcon Tubes.

烈性噬菌体（virulent－phage）和温和噬菌体（temperate－phage）
噬菌体(bacteriaphage or phage)是病毒的一类，结构很简单，基本上由一个蛋白质外壳包裹着一些核酸组成的。噬菌体的多样性来自于组成其外壳的蛋白质的种类，以及其染色体的类型和结构的不同。（一）烈性噬菌体（ virulent phage）遗传学上应用最广泛的烈性噬菌体是大肠杆菌（ E.

DNA体外转染试剂_如何准备转染所需的质粒DNA
转染效率受到诸多因素的影响，除了细胞、培养基和载体等影响因素外，另外一项非常重要的因素便是DNA的质量。为了比较不同厂家的转染效率，我们分别从三家不同的供应商购买了质粒制备试剂盒来制备pEGFP-N3质粒DNA，并通过不同的方法将制备的pEGFP-N3质粒转运至NIH-3T3细胞。pEGFP-N3质
