全層析工藝制備10%靜注人免疫球蛋白及檢測(cè)分析
[Abstract]:Objective to study the feasibility of 10% intravenous injection of human immunoglobulin by complete chromatography combined with ultrafiltration dialysis and three steps of virus inactivation / removal. Methods 10IVIGs were purified by full chromatography, and the recoveries were calculated, and the key indexes were determined by referring to the quality standards of human immunoglobulin (Ig) injected intravenously in the PRC Pharmacopoeia and the European Pharmacopoeia 8.0. The impurity protein and Ig G subclass of the final product were detected and analyzed by scatter turbidimetry. Results the average recovery of IgG was 60.86, and the coefficient of variation was 0.7%, which indicated that the process had good reproducibility, and the key indexes, such as purity and molecular size distribution, reached the requirements of the Pharmacopoeia of the people's Republic of China and the Pharmacopoeia of Europe. The content of impurity protein IgA2.87 mg / L Ig M0.15 mg / L was lower than that of impurity protein IgA2.87 mg / L, and the composition ratios of four subgroups (%) were 55.1 鹵2.5ng / L, 35.8 鹵2.3n, 5.39 鹵0.93 and 3.66 鹵0.16, respectively. Conclusion the whole chromatographic process of our company can efficiently prepare 10%IVIG products that meet the international standards.
