The dihydrofolate reductase-deficient Chinese hamster ovary (CHO) cell line DG44 is the dominant mammalian host for recombinant protein manufacturing, in large part because of the availability of a well-characterized genetic selection and amplification sys ...
DNA uptake by polyethylenimine (PEI)-mediated transfection was investigated in Chinese hamster ovary (CHO DG44) cells. Rapid DNA uptake was observed with the maximum occurring during the first 45-60 min after addition of PEI-DNA complexes to cells. With lo ...
Recently, a new method for the specific covalent labeling of fusion proteins in vitro and in living cells has been developed. This method is based on the unusual mechanism of a DNA repair protein: the O6-alkylguanine DNA alkyltransferase (AGT). In addition ...
Recent advances in the fields of biotechnology and medicine have intensified the necessity for pharmaceutical-grade biomacromolecules purification (e.g. enzymes, antibodies, plasmid DNA). One of the key factors for a successful downstream process is the po ...
Recently, using HIV-1-derived lentivectors, we obtained efficient transduction of primary human B lymphocytes cocultured with murine EL-4 B5 thymoma cells, but not of isolated B cells activated by CD40 ligation. Coculture with a cell line is problematic fo ...
Recombinant proteins are gaining in importance for therapeutic applications. The proteins are expressed in stable cell lines, within which recombinant DNA has incorporated into the host cells genome. Identification and isolation of extremely high producers ...
The Gam1 protein of the avian CELO adenovirus activates transcription through inhibition of histone deacetylase 1 (HDAC1). We investigated the effect of Gam1 on both transient and stable transgene expression in Chinese hamster ovary (CHO) cells, one of the ...
Recent advances in genomics, proteomics, and structural biology raised the general need for significant amounts of pure recombinant protein (r-protein). Because of the difficulty in obtaining in some cases proper protein folding in bacteria, several method ...
Novel approaches for the development of integrated molecular analysis tools have been tested. A label-free method for molecular detection and characterization based on UV absorbance have been applied and two technologies of silicon photodetectors arrays ha ...
The main goal of CleanEx is to provide access to public gene expression data via unique gene names. A second objective is to represent heterogeneous expression data produced by different technologies in a way that facilitates joint analysis and cross-data ...
