Kyiv is Ukraine's capital and largest city. Home to 3 million people, this area has a rich history of agriculture and industry. The Dnieper River is Ukraine's largest river and it passes through the center of Kyiv.

Physico-chemical and biological properties of solvent/detergent treated immunoglobuin G preparations.

Protein composition homogeneity, fraction composition, molecular weight composition, anticomplementary activity, anti-A and anti-B haemagglutinins, specific activity, and pyrogens were studied in intramuscular and intravenous immunoglobulin G preparations, treated and non-treated with solvent/detergent mixture for virus inactivation. Physico-chemical and biological properties retention is shown. Quality of immunoglobulin preparations was improved due to purification by the methods of anion- and cation- exchange preparative low pressure liquid chromatography.
