Abstract: Disclosed are compositions, reagents, methods, assays, and kits for quantitative and sensitive detection of target ribonucleic acid (RNA) sequences, particularly target RNA sequences that contain RNA spliced sites, hairpin stem-loops or other topological configurations of RNA secondary, tertiary, and quaternary structure, as well as linear RNA sequences. In some embodiments, fluorogenic modified-backbone oligonucleotide probes are employed for specific sequence hybridization across the target site, followed by chemical autoligation to produce a fluorescent molecule within the ligated probes. The autoligation detection reaction is performed isothermally or through thermocycling.

Abstract: Human antibodies, preferably recombinant human antibodies, that specifically bind to human tumor necrosis factor ? (hTNF?) are disclosed. These antibodies have high affinity for hTNF? (e.g., Kd=10?8 M or less), a slow off rate for hTNF? dissociation (e.g., Koff=10?3 sec?1 or less) and neutralize hTNF? activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, of the invention are useful for detecting hTNF? and for inhibiting hTNF? activity, e.g., in a human subject suffering from a disorder in which hTNF? activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies of the invention, and methods of synthesizing the recombinant human antibodies, are also encompassed by the invention.
