Vector: pBP96 (plasmid)
Construction: BLUR8, HIS3
Construct size (kb): 4.599999904632568
Features: marker(s): ampR, HIS3
YI-type (integrating) shuttle vector
Restriction digests of the clone give the following sizes (kb): BamHI--3.0, 1.6; EcoRI--4.6; PstI--3.3, 1.3.
Digestion with BamHI removes the plasmid sequences from the Alu ends for targeting integration.
Transformation into pools from a YAC library derived from a human-mouse somatic cell hybrid, and selection for His+, resulted in an approximate 50-fold enrichment for Alu-containing YACs.
Larger YACs were preferentially selected. Some YACs demonstrated loss of Alu-containing restriction fragments suggesting internal deletions resulting when the vector targeted two Alu sequences in the YAC.
YI-type shuttle integrative vector targeting human Alu sequences in YAC libraries derived from somatic cell hybrids.
Constructed by inserting a blunt-ended 1.2 kb fragment containing S. cerevisiae HIS3 into the blunted MscI within the Alu sequence of BLUR8.
The order of the major features in this plasmid is: bla - BamHI - Alu - HIS3 - Alu - BamHI.
