Description générale

The DNA of bacteriophage lambda contains 48,502 nucleotide pairs forming a linear duplex. The 5′ ends of this DNA molecule have self-complementary single-stranded protrusions of 12 nucleotides that can anneal to form circles. Upon entry into the host cell, the DNA circularizes in the presence of DNA ligase. Many such circles are generated during the early lytic infection. At a later stage in replication, these individual circles/rings are converted to linear concatemers by a process called rolling-circle replication. The linear concatemers are cleaved during packaging to form monomeric chromosomal units by the enzyme DNA terminase.

Application

DNA, lambda has been used to spike peripheral blood leukocytes (PBL) before genomic DNA isolation. It has also been used in the preparation of biotinylated double-stranded DNA (dsDNA) substrate.

Qualité

The DNA shows the typical cleavage pattern for wild type λDNA in gel electrophoresis after cleavage with restriction endonucleases EcoR I and Hind III.
