    Abstract: Methods and compositions are disclosed for reducing non-specific binding in a binding assay for the determination of an analyte in a sample where one of the reagents for conducting the binding assay comprises a solid support comprising a polysaccharide. The method comprises including in an assay medium for conducting the binding assay a soluble compound comprising a protein linked to a polysaccharide. Also disclosed are methods and compositions for determining the presence and/or amount of an analyte in a sample suspected of containing the analyte. The methods include as reagents a solid support comprising a polysaccharide and a soluble compound comprising a protein linked to a polysaccharide.

    Abstract: Methods, compositions and kits are disclosed. Enzyme conjugates of Formula (I) are employed in assays for the determination of an methylenedioxyamphetamine, a methylene-dioxyethamphetamine, and/or a methylenedioxymethamphetamine. Immunogenic conjugates of Formula I are employed to prepare antibodies for an methylenedioxyamphetamine, a methylenedioxyethamphetamine, and/or for a methylene- dioxymethamphetamine for use in assays for the determination of an methylenedioxyamphetamine, a methyl enedioxyethamphetamine, and/or a methylene-dioxymethamphetamine. The enzyme conjugates may also be employed to screen antibodies for use in such methods.

    Abstract: Methods, compositions and kits are disclosed. The methods are directed to determining the presence of entactogen analytes such as, for example, 3,4-methylenedioxamphetamine (MDA), 3,4-methylenedioxy-methamphetamine (MDMA), 3,4-methylenedioxy-ethylamphetamine (MDEA) and 4-hydroxy-3-methoxy-methamphetamine (HMMA). The method comprises providing in combination in a medium (i) a sample suspected of containing the compound and (ii) an antibody raised against a compound of Formula I that comprises a protein. The medium is examined for the presence a complex comprising the compound and the antibody where the presence of such as complex indicates the presence of the compound in the sample. In one aspect of the above embodiment, the combination further comprises a label conjugate of the compound Formula I.
