High-titer λ phage progenitors can be prepared from small quantities of liquid cultures. This method was first used by Leder et al. (1977). In general, i
The preparation of λ phage progenitors derived from a single phage spot is usually done by two methods: (i) plate lysis, which is a method of phage proli
This protocol describes how to hybridize radiolabeled probes to DNA of transforming bacteria immobilized on filter membranes, and methods for recovering clones
Genetically homologous λ phage protospecies are obtained by "picking" a completely separate phage spot and preserving agar/agarose containing the lysate
Phages originate from the infection of a single bacterium by a single phage particle. The daughter virus particles synthesized after the first infection adsorb
Using this scheme, well-sheared, high-quality salmon sperm stretcher DNA can be obtained, which can be used in transformation experiments and other experiments
Restriction endonucleases are a class of DNA hydrolases that recognize specific nucleotide sequences in double-stranded DNA molecules, and the discovery and app
Mass preparation of λ phage can be obtained by either low-mass infection of bacterial cultures or high-mass infection. Immediately after low magnificatio
