应用体积排阻色谱法、非还原SDS—PAGE法、离子交换色谱法分析抗EGFR单克隆抗体纯度.结果表明:三种分析方法分析抗EGFR单克隆抗体纯度表现出明显差异,体积排阻色谱法检测出多聚体含量、非还原SDS—PAGE法检测出降解片段的含量、离子交换色谱法检测出多个电荷异构体.基于单克隆抗体结构的多样性,有必要开发多种分析方法监控单克隆抗体的纯度.
應用體積排阻色譜法、非還原SDS—PAGE法、離子交換色譜法分析抗EGFR單剋隆抗體純度.結果錶明:三種分析方法分析抗EGFR單剋隆抗體純度錶現齣明顯差異,體積排阻色譜法檢測齣多聚體含量、非還原SDS—PAGE法檢測齣降解片段的含量、離子交換色譜法檢測齣多箇電荷異構體.基于單剋隆抗體結構的多樣性,有必要開髮多種分析方法鑑控單剋隆抗體的純度.

The purity of anti- EGFR monoclonal antibody was analyzed by such analysis methods as size exclusion chro- matography(SEC), non- reducing SDS -PAGE and ion exchange chromatography. Significant difference was observed in pu- rity analysis, which was showed that aggregates could be detected by SEC, degradation fragment was found by non- reduc- ing SDS- PAGE, and several charge isoforms were detected by ion exchange chromatography. It is essential to apply many analysis methods to the purity of monoclonal antibody due to its structure diversity.
