    • A bioerodible composition for delivery of a bioactive agent is the reaction product of a reaction mixture which includes an oxidized dextran solution, and a mixture of solids containing a dihydrazide, a bioactive agent, and optionally a pH adjusting agent in an amount sufficient to achieve a pH of the reaction mixture of 6 or less. The composition may include a release agent for controlled release of the bioactive agent from the composition. A bioactive agent may therefore be administered to a body site in need of the same by providing a first aliquot portion of a reaction mixture comprising an oxidized dextran solution, and a second aliquot portion of a reaction mixture comprising a mixture of solids comprised of a dihydrazide, a bioactive agent, and a solid acid which is present in an amount sufficient to achieve a pH of the reaction mixture of 6 or less, mixing the first and second aliquot portions to form the reaction mixture thereof, and thereafter installing the reaction mixture at the body site and allowing a solidified bioerodible drug delivery composition to be formed thereby in situ.

    • Binding assay methods involving determining the presence of analytes in samples through enzymatic formation of detectable substances in amounts related to the amount of analyte present in the sample and monitoring for the presence of the substances in distinct phases. Methods according to the invention include use of labelled materials which associate with the analyte to be determined or compete with the analyte for association with an added binder. The labelled materials employed include label portions which enzymatically form substances from substrates provided in or existing as a first phase, or, upon enzymatic treatment in a first phase, disassociate into substances capable of existing in or as a second distinct phase. Formation of the detectable substances is monitored by determining the transfer of the substance to a second distinct phase in contact with the first phase or by determining formation of a second distinct phase. The assays are useful in determining human IgG protein in blood samples and other constituents of blood or other biological samples without elaborate instrumentation, allowing for practice outside the clinical laboratory.
