Cloning vectors derived from filamentous phage are extremely useful because they allow cloned DNA to be isolated as either single- or double-stranded DNA. This unit contains protocols for preparing both forms of DNA and for characterizing inserts in M13-derived vectors. A protocol is also presented for preparing single-stranded DNA from plasmids using superinfection with helper phage. This method is advantageous because it allows cloned DNA to be maintained in the form of a plasmid while permitting single-stranded DNA to be isolated for DNA sequencing.
