Purification of Bacteriophage Lambda Repressor [PDF]
Bacteriophage lambda repressor controls the lysogeny/lytic growth switch after infection of E. coli by lambda phage. In order to study in detail the looping of DNA mediated by the protein, tag-free repressor and a loss-of-cooperativity mutant were expressed in E.coli and purified by (1) ammonium sulfate fractionation, (2) anion-exchange chromatography ...

Revisiting bistability in the lysis/lysogeny circuit of bacteriophage lambda. [PDF]
The lysis/lysogeny switch of bacteriophage lambda serves as a paradigm for binary cell fate decision, long-term maintenance of cellular state and stimulus-triggered switching between states. In the literature, the system is often referred to as "bistable.

Bacteriophage Lambda: a Paradigm Revisited [PDF]
ABSTRACT Bacteriophage lambda has an archetypal immunity system, which prevents the superinfection of its Escherichia coli lysogens. It is now known that superinfection can occur with toxigenic lambda-like phages at a high frequency, and here we demonstrate that the superinfection of a lambda lysogen can ...

On the Internal Structure of Bacteriophage Lambda [PDF]
The structure of bacteriophage lambda has been studied by electron microscopy of negatively stained particles. The phage particles will eject their DNA if they are heated or dialyzed against a chelating agent. The ghost particles, so formed, have a channel running down their tails.

Transduction of bacteriophage lambda by bacteriophage T1 [PDF]
When bacteriophage T1 was grown on bacteriophage lambda-lysogenic cells, phenotypically mixed particles were formed which had the serum sensitivity, host range, and density of T1 but which gave rise to lambda phage. T1 packaged lambda genomes more efficiently both when the length of the prophage was less than that of wild-type lambda and when the host ...

A one-step miniprep for the isolation of plasmid DNA and lambda phage particles. [PDF]
Plasmid DNA minipreps are fundamental techniques in molecular biology. Current plasmid DNA minipreps use alkali and the anionic detergent SDS in a three-solution format.

A forward-genetic screen and dynamic analysis of lambda phage host-dependencies reveals an extensive interaction network and a new anti-viral strategy. [PDF]
Latently infecting viruses are an important class of virus that plays a key role in viral evolution and human health. Here we report a genome-scale forward-genetics screen for host-dependencies of the latently-infecting bacteriophage lambda.

Bacteriophage lambda as a cloning vector [PDF]
Extensive research has been directed toward the development of multipurpose lambda vectors for cloning ever since the potential of using coliphage lambda as a cloning vector was recognized in the late 1970s. An understanding of the intrinsic molecular organization and of the genetic events which determine lysis or lysogeny in lambda has allowed ...

Host-parasite coevolution promotes innovation through deformations in fitness landscapes
During the struggle for survival, populations occasionally evolve new functions that give them access to untapped ecological opportunities. Theory suggests that coevolution between species can promote the evolution of such innovations by deforming ...
