Abstract：
:Complementation of chromosomal mutations in trans can introduce artifacts due to the number of episomal copies of the gene in question. One solution is to study the gene expressed at a single ectopic site in cis. We have designed and constructed a vector that allows homologous recombination into a gene encoding a frame-shifted IS1016-V6 protein in the Haemophilus influenzae Rd KW20 chromosome (HI1018). This site is the location of the > or = 35 kilobase capsule locus in encapsulated type b and d strains. This locus is not present in the nontypeable Rd KW20 strain, thus allowing ectopic expression of genes homologously recombined into HI1018 without polar effects.
