Infection of a strain lysogenic for bacteriophage P1 CM with P1::Tn5 followed by simultaneous selection for the chloroamphenicol resistance associated with the resident prophage and the kanamycin resistance associated with Tn5 results in a large number of independent Tn5 insertion mutations. This superinfection-selection protocol is a fast, easy, and safe way to isolate null mutations in enteric bacteria without generating unwanted cryptic mutations elsewhere in the genome.
用P1::Tn5感染对噬菌体P1 CM呈溶原性的菌株,随后同时选择与驻留原噬菌体相关的氯霉素抗性和与Tn5相关的卡那霉素抗性,会产生大量独立的Tn5插入突变。这种超感染选择方案是一种快速、简便且安全的方法,可用于在肠道细菌中分离无效突变,而不会在基因组的其他位置产生不需要的隐蔽突变。
