Provided is a conjugate including a pharmacologically active substance covalently bound to chitosan or its derivative and a method for transmucosal delivery of a pharmacologically active substance using the same. Specifically, a conjugate includes a pharmacologically active substance covalently bound via a linker to chitosan; and a pharmaceutical composition for transmucosal administration of a drug includes the aforementioned conjugate and a pharmaceutically acceptable carrier. Further provided is a method for in vivo delivery of a pharmacologically active substance via a transmucosal route, by covalent binding of the active substance with chitosan or its derivative via a linker. The conjugate in accordance with the present invention exhibits excellent absorption rate and biocompatibility in biological mucous membranes, particularly mucous membranes of the alimentary canal (especially the gastrointestinal tract), in vivo degradability, and superior bioavailability even with oral administration, thus enabling treatment of diseases via oral administration of a drug.

Provided is a non-specific reaction inhibitor for achieving the accurate detection and quantitation of a trace component (a target substance) contained in a sample, in an immunoassay, by simply and effectively inhibiting a non-specific reaction associated with the measurement.
The non-specific reaction inhibitor comprises a substance of the formula I:
wherein R1 and R2 together form a double bond between carbons, to which they are respectively bonded directly, or R1 is a hydrogen atom and R2 is a group formed by removing H from an SH-group-containing compound, B is a support, and L is a spacer arm portion.
The present invention relates to a loaded latex particle comprising a latex material made from a mixture represented by formula (X)m-(Y)n-(Z)o-(W)p, wherein Y is at least one monomer with at least two ethylenically unsaturated chemical functionalities; Z is at least one polyethylene glycol macromonomer with an average molecular weight of between 300 and 10,000; W is an ethylenic monomer different from X, Y, or Z; and X is at least one water insoluble, alkoxethyl containing monomer; and m, n, o, and p are the respective weight percentages of each monomer. The particle may be loaded with a fluorescent dye.
