Site-directed mutagenesis in Escherichia coli of a stable R772::Ti cointegrate plasmid from Agrobacterium tumefaciens.
The host range of an octopine Ti plasmid is limited to Rhizobiaceae. This has been extended also to Escherichia coli in the form of a stable cointegrate with the wide-host-range plasmid R772. Its structure was studied by constructing a physical map of R772 and of the R772::pTiB6 cointegrate. An insertion sequence present in R772, called IS70, turned out to be involved in cointegrate formation. ...
متن کاملMobilization of morganocin 174 plasmid and kinetics of morganocin production in Proteus and Escherichia coli hosts.
Morganocin 174 is coded by a plasmid, Mor174. The plasmid is not self-transmissible but may be mobilized by resistance factor R772. Morganocin synthesis in all Proteus and Providencia strains carrying Mor174 was characterized by a longer lag period after induction and higher titers than in Escherichia coli B(Mor174). The low titers obtained in E. coli B(Mor174) are due to a heatstable inhibitor...

Prostate-specific antigen (PSA) is a recently described marker for prostate carcinoma (1). In patients with prostatic cancer the concentration of PSA in serum can be as much as 10 mg/L, whereas concentrations in healthy men are <2.8 zg/L (2). Hybritech’s immunoradiometric assay for PSA has been in routine use in our laboratory for 15 months. Its reproducibility is generally good, but two sample...

Abstract Background and Objective: the inhibition of tumor-associated angiogenesis can significantly reduce the tumor proliferation. The basic fibroblast growth factor (bFGF), an important angiogenic factor, is considered as a potential therapeutic target for cancer therapy. The purpose of this study was evaluating, designing and construction of new recombinant DNA molecule in order to ha...
