E E Potemkina, and L V Galkina, and T M Khrometskaia, and E E Krylova, and T A Mamaeva

The physicochemical and immunological properties of the experimental batches of the preparations of placental immunoglobulin, obtained by some methods of chemical modification of the molecule of IgG, have been studied. The possibility of abolishing the anticomplement properties of the preparations treated with sulfitolytic agents manufactured in the USSR has been shown. The optimum conditions permitting the production of the preparation with faintly pronounced anticomplement properties and the full monomer structure of its molecule have been established.

D007120 Immunochemistry Field of chemistry that pertains to immunological phenomena and the study of chemical reactions related to antigen stimulation of tissues. It includes physicochemical interactions between antigens and antibodies.
D007202 Indicators and Reagents Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.

D002627 Chemistry, Physical The study of CHEMICAL PHENOMENA and processes in terms of the underlying PHYSICAL PHENOMENA and processes. Physical Chemistry,Chemistries, Physical,Physical Chemistries
D003169 Complement Inactivator Proteins Serum proteins that negatively regulate the cascade process of COMPLEMENT ACTIVATION. Uncontrolled complement activation and resulting cell lysis is potentially dangerous for the host. The complement system is tightly regulated by inactivators that accelerate the decay of intermediates and certain cell surface receptors.
