vector containing primer sites useful for sequencing
vector for generating nested deletions of cloned inserts
vector permitting visual detection of recombinants
Restriction digests of the vector give the following sizes (kb): HindIII--8.8; BamHI--8.8; EcoRI--8.8.
To obtain ordered deletions of a genomic fragment, the DNA of interest is cloned into the BamHI site, followed by digestion of the plasmid with one of 4 restriction enzymes (KpnI, SalI, XhoI, SacI) and subsequent religation to obtain a set of subclones.
IS1-promoted deletions can be selected by plating each subclone on deoxygalactose-containing media. Appropriate deletion clones should be Gal- and strS.
Cloning vector useful for sequencing genomic DNA inserts by generation of an ordered set of deletion subclones.
Sequencing of the cloned inserts can be performed using the -23 IS1 primer (5' AAA ACA CCA TCA TAC ACT AA 3') published in Methods in Enzymology 155:177-204, 1987.
