[Vectors--derivatives of phage lambda for construction and analysis of genome libraries].
Basic features of lambda phage derived, cosmid and plasmid vectors are described. Plasmid vectors combine the most useful features of phage and plasmid vectors. Plasmids can exist in vivo as a plasmid or as a phage. Plasmid vectors are similar to large capacity phage vectors, but can be maintained in vivo without a stuffer fragment. That is why plasmids are easier in preparation for cloning than phage vectors. The yield of recombinants is higher with plasmid vectors (up to 3.10(6)) and the background of non-recombinants in the library is lower. Analysis of recombinant plasmids is more simple and effective than analysis of recombinant phages and plasmids. Probably plasmid vectors will soon be widely used instead of phage or cosmid vectors for genomic libraries construction and analysis.
