Escherichia Coli Vector. A bacteriophage lambda cloning vector was designed to facilitate the isolation of genes from procaryotic organisms by complementation of Escherichia coli mutants This vector lambda SE4 was constructed by attaching a verylowcopynumber replication system (from the plasmid NR1) and a spectinomycin resistance gene to the left arm of lambda 1059 (Karn et al Proc Natl.

Escherichia coli (/ ˌ ɛ ʃ ə ˈ r ɪ k i ə ˈ k oʊ l aɪ /) also known as E coli (/ ˌ iː ˈ k oʊ l aɪ /) is a Gramnegative facultative anaerobic rodshaped coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warmblooded organisms Most E coli strains are harmless but some serotypes (EPEC ETEC etc) can cause serious food poisoning in.

A plasmid vector has been constructed that directs the synthesis of high levels (approximately 2% of total cellular protein) of fusions between a target protein and maltosebinding protein (MBP) in Escherichia coli The MBP domain is used to purify the fusion protein in a one step procedure by affinity chromatography to crosslinked amylose resin The fusion protein contains the.
