摘要:
The present invention relates generally to improved methods for the expression of recombinant protein products under the transcriptional control of an inducible promoter, such as an araB promoter, in bacterial host cells that are deficient in one or more of the active transport systems for the inducer of the inducible promoter. The present invention also relates to improved bacterial host cells that are deficient in one or more of the active transport systems for an inducer of an inducible promoter, such as arabinose for an araB promoter, and contain an expression vector encoding a recombinant polypeptide under the transcriptional control of the inducible promoter, such as an araB promoter.

The present invention relates to the discovery, identification and characterization of nucleotides that encode Ob receptor (ObR), a receptor protein that participates in mammalian body weight regulation. The invention encompasses obR nucleotides, host cell expression systems, ObR proteins, fusion proteins, polypeptides and peptides, antibodies to the receptor, transgenic animals that express an obR transgene, or recombinant knock-out animals that do not express the ObR, antagonists and agonists of the receptor, and other compounds that modulate obR gene expression or ObR activity that can be used for diagnosis, drug screening, clinical trial monitoring, and/or the treatment of body weight disorders, including but not limited to obesity, cachexia and anorexia.

摘要:
Bifunctional green fluorescent protein (GFP)-annexin fusion proteins combine the inherent strong visible fluorescent properties of GFPs with the anionic phospholipid binding specificity of annexins. Recombinant host cells, especially bacteria, are used to efficiently express the fusion proteins in high yield and soluble form, suitable for rapid, one-step affinity purification. Uses include of selective cellular and biochemical labeling, particularly anionic species, such as selectively labeling apoptotic cells.
摘要:
Methods for enhancing the production of interferon in animal cell culture are described. These methods rely on the manipulation of the cellular levels of certain inducers of interferon production, in particular cellular levels of double-stranded-RNA-dependent kinase (dsRNA-PKR, or PKR). In cell cultures that overproduce PKR, interferon synthesis is induced to high levels, and significant amounts of interferon can be recovered without conventional induction of interferon by virus.
