半岛bd体育手机客户端 说明
一般描述
Phage DNA is isolated from infected E. coli, passed through a series of enzymatic steps before final phenol-chloroform extraction. This methylated lambda DNA is not completely digested by Bcl I, Cla I, Mbo I, Mbo II, Taq I or Xba I whereas non-methylated lambda DNA(product number D3654) is only partially cleaved.
特异性
Unique restriction sites:ApaI,NaeI,NarI,NheI,PaeR7 I,SnaBI,XbaI andXhoI. Methylated lambda is partially cleaved byBclI,ClaI,MboI,MboII,TaqI andXbaI.
应用
Lambda Phage DNA, Methylated fromEscherichia colihost strain W3110 is suitable for use as a substrate for restriction enzymes. It was used to study the attractive forces between condensed DNA double helix by combining single-molecule magnetic tweezers and osmotic stress.35S-labeled Lambda Phage DNA, Methylated fromEscherichia colihost strain W3110 was also used to standardize a method of measuring dissolved DNA in seawater.
Lambda Phage DNA, Methylated fromEscherichia colihost strain W3110 has been used:
单位定义
