Abstract: Oligonucleotides having an internal acyclic linker residue, and the preparation and uses thereof, are described. Such uses include the preparation of acyclic linker-containing antisense oligonucleotides, and their use for the prevention or depletion of function of a target nucleic acid of interest, such as RNA, in a system. Such a prevention or depletion of function includes, for example, the prevention or inhibition of the expression, reverse transcription and/or replication of the target nucleic acid, as well as the cleavage/degradation of the target nucleic acid. Accordingly, an oligonucleotide of the invention is useful for analytical and therapeutic methods and uses in which the function of a target nucleic acid is implicated, as well as a component of commercial packages corresponding to such methods and uses.

Abstract: The invention relates to oligonucleosides having alternating segments of sugar-modified nucleosides and 2?-deoxynucleosides, and uses thereof. The invention further relates to oligonucleotides having alternating segments of sugar-modified nucleotides and 2?-deoxynucleotides, and uses thereof. Such uses include the preparation of antisense oligonucleotides and their use for the prevention or depletion of function of a target nucleic acid of interest, such as an RNA, in a system. Accordingly, an oligonucleotide of the invention is useful for therapeutic, analytical and diagnostic methods and uses, as well as a component of compositions and commercial packages corresponding to such methods and uses.

Abstract: A method for measuring heterodimerization of HIV RT, which comprises the steps of: a) providing a first solution comprising p66 subunit homodimers in the presence of a dissociation agent; b) contacting the first solution with p51 RT subunits and incubating in the presence of a reassociation buffer to allow association of a complex of p66/p51 RT subunits, wherein one of the subunits comprises an affinity tag and the other of the subunits comprises a detectable label; c) contacting the incubate of step b) with an affinity medium under conditions that enable the p66/p51 complex to bind to the affinity medium; and d) determining the amount of complex formed by measuring the level of detectable label bound to the affinity medium (or by measuring the reconstituted RT polymerase activity).

Abstract: A method for measuring heterodimerization of HIV RT, which comprises the steps of:

Abstract: Compositions for delivery having a biological agent or derivative thereof, and a poly(oxyethylene)-poly(oxypropylene) block copolymer. The compositions are useful in immunodeficiency infection virus therapy. The invention also encompasses methods of treatment using the same.
