title: [Rapid isolation of phage lambda DNA].
abstract: A modified procedure in two versions (micro, for 10 ml of phage lysate, and macro, for 200-500 ml) is described for preparing lambda phage DNA. The main advantage of the modified method is that it gives a possibility to isolate high-quality DNA from lambda phage lysates in 2-3 hrs. Only standard solutions (TE, NaCl, SDS, MgCl2, EDTA, RNAse A) were used throughout the whole protocol. Incubation with DNAse I and proteinase K was omitted and in microvariant concentration of the phage by PEG 6000 was excluded. Digestion by RNAse A was performed in solution with EDTA and SDS and leads to RNA degradation. The yields of DNA (0.5-2 micrograms per ml of L-broth) are similar to those obtained by other methods. DNA quality is better than in the samples of DNA prepared by other express-methods and practically the same as after CsCl centrifugation. DNA can be used for splitting by restriction enzymes, cloning and gene library construction.
