Immunologically invisible carrier molecules connect a plurality of copies of an immunologically active molecule in an immunologic assay.

Borellia burgdorferi epitope peptides

A novel compound comprising an immunologically invisible polyethylene glycol copolymer is used to carry one or more immunologically reactive substances. The novel compounds may be used as part of kits for immunological assays.

Immunological test kit comprising an immunologically invisible peg copolymer conjugated to one or more immunologically reactive substances

This invention pertains to disulfide-linked conjugates of therapeutic agents containing at least one thioamide group with polymer comprising at least one thiol group, so as to provide a controlled release pharmaceutical composition for administration to animals for the prophylaxis or treatment of various conditions or diseases. The therapeutic agent conjugate may comprise an inactive or weakly active prodrug form which may be converted into the original therapeutic compound by the natural action of reducing agents in vivo. The composition may comprise a mixture of polymers each with a different thioamide-containing agent attached, or a polymer conjugated with a mixture of thioamide-containing agents. Modified properties of the therapeutic compound potentially provided by the polymer itself, as well as by other compounds also appended to the polymer, include but are not limited to greater water solubility, longer in-vivo half-life (due to larger size of the conjugate), slower release from a sustained-release depot (due to larger size of the conjugate), better oral bioavailability and tissue-specific targeting.
