pRS426 Desciption

The order of the major features in this plasmid is:ori(f1) - lacZ - T7 promoter - MCS (KpnI-SacI) - T3 promoter - lacI - ori(pMB1) - ampR - ori (2 micron) - URA3. Contains the REP3 and FRT sequences necessary for high copy propagation in yeast. In S. cerevisiae, the copy number is about 20 per haploid cell. In non-selective growth, plasmids are lost through mitotic segregation at rates in the range of 4.4 + or - 1.4% of progeny per doubling. YE-type shuttle vector encoding the beta-galactosidase alpha peptide, permitting blue-white visual detection. Can be used to produce ssDNA. Contains promoters for in vitro RNA synthesis and priming sites useful for sequencing. Restriction digests of the clone give the following sizes (kb): BamHI--5.8; EcoRI--5.8; PstI--4.0, 1.7; PvuII--5.2, 0.54. (ATCC staff) Medium is 1227 LB plus ampicillin.
