DNA extracted from lambda-derived vectors is typically subcloned into plasmid or filamentous phage vectors. The first two protocols describe methods for isolating phage DNA from large- and medium-scale liquid lysates. These two methods use either density-gradient centrifugation or ion-exchange chromatography to purify the phage particles. The third protocol describes a rapid procedure for isolating phage DNA, suitable for small-scale liquid lysates.
