摘要:
A novel artificial carrier is disclosed which is prepared from gelatin, a water-soluble polysaccharide, a sodium metaphosphate and an aldehyde. The carrier can be used to immobilize antibodies, antigens or enzymes. Immobilized antigens and antibodies can be used as a diagnostic reagent in assays involving antigen-antibody reactions.
摘要:
Support matrices for immobilized enzymes which comprise a combined organic-inorganic support may be prepared by treating a solid, porous, inorganic, water-insoluble support such as an inorganic porous metal oxide with a styrene monomer, polymerizing the styrene on the solid support at polymerizing conditions, nitrating the resultant polystyrene-solid support composite and thereafter reducing the nitrated polystyrene-solid support composite to form an aminopolystyrene-solid support matrix.

摘要:
The invention relates to a dye-labeled antibody conjugate comprising an antibody conjugate and a cyanine dye. The dye-labeled antibody conjugate is prepared by polymerizing an antibody such as mouse IgG in phosphate buffer using a polyfunctional reagent such as dithiobis(sulfosuccinimidylpropionate), and stirring the antibody and a cyanine dye represented by Formula I . The dye-labeled antibody conjugate is more sensitive to antigens than conventional dye-labeled antibodies because it has many reactive sites to antigens. ##STR1## wherein X represents a halogen, M represents a hydrogen or alkali metal, and n represents an integer of 1 to 4
