A new selective phage cloning vector, lambda 2001, with sites for XbaI, BamHI, HindIII, EcoRI, SstI and XhoI.
An improved bacteriophage lambda cloning vector, lambda 2001, has been constructed. The phage includes a 34-bp polylinker oligonucleotide which introduces cleavage sites for XbaI, SstI, XhoI, EcoRI, HindIII and BamHI, and can accommodate 10-kb to 23-kb fragments. Inserts that destroy the BamHI or XhoI cloning sites may be recovered by excision at flanking sites in the polylinker sequence. Insertion of foreign DNA into lambda 2001 generates phage with a Spi- phenotype. The recombinant phage are able to grow on P2 lysogens but the parental vector phages are not. In the course of this work, the polylinker sequence was also introduced into M13mp8. This produced a new vector, M13mp12, with cloning sites for EcoRI, SmaI, XbaI, SstI, XhoI, BamHI, and HindIII.
