    摘要: The present invention provides a protein delivery means (e.g., a polyion complex) which allows efficient introduction into cells (particularly into the cytoplasm), is highly stable in serum, and is also widely applicable. The polyion complex of the present invention comprises a cationic polymer having a polycation moiety and a charge-conversional protein whose overall charge is converted from basic or neutral to acidic by a specific charge regulator.

    摘要: This invention provides a method to detect analyte which comprises preparing fine particles which have a chargeable group in their core and a hydrophilic polymer chain in their shell; obtaining an agglutinated matter by forming a biologically specific bond between a specific residue on the surface of fine particles and analyte, and by simultaneously forming a bond by the electrostatic interaction between impure protein and said particles; and subsequently cleaving only the latter bond by raising ionic intensity. Thus, this invention provides a method to detect analyte with rapidity and high sensitivity with use of agglutination reaction.
