We report the synthesis of the fluorescent 2'-deoxycytidine analogue 5-methylpyrimidin-2-one nucleoside, its incorporation at three specified sites in a single 60-nucleotide DNA molecule, and the use of its total and polarized intrinsic fluorescence to characterize RecA-DNA complexes.

A stable mammalian cell line expressing highly active bovine interferon-gamma (BoIFN-γ) was generated using Flp recombinase-mediated integration. This recombinant 293 cell line (B1) efficiently secreted FLAG-tagged BoIFN-γ protein into the culture supernatant, as determined by ELISA and Western blot. The recombinant BoIFN-γ exhibited high anti-viral(More)
We established an ELISPOT for bovine interferon-gamma (BoIFN-γ), and applied it in the diagnosis of bovine tuberculosis (bTB). Monoclonal antibodies that can bind with native BoIFN-γ were screened as the coating antibody and detecting antibody. After optimization of detecting conditions including coating antibody concentration, cell number, and detecting(More)
Bovine interferon-gamma (BoIFN-gamma) gene was amplified by reverse transcription polymerase chain reaction (RT-PCR) from total RNA of bovine spleen lymphocytes stimulated with ConA. The products of RT-PCR were cloned into pVAX1 vector, positive recombinant clone was identified by restriction enzyme digestion and sequencing. The recombinant plasmid(More)
