中文摘要:
      目的采用超高效液相色谱 -飞行时间高分辨质谱联用技术,对重组全人抗程序性死亡配体 -1(PD-L1)单克隆抗体的 N糖谱进行定性和定量分析。方法选取 2020年 3月至 2023年 3月共 11批次重组全人抗 PD-L1单克隆抗体[安徽省食品药品检验研究院生物制品(药理)室]其中正常批次 3批, 6个月加速试验正向和倒向放置分别 3批, 36个月长期试验正向和倒向放置分别 1批。采用 2-氨基苯甲酰胺,(2-AB)标记法,通过高分辨质谱对样品的 N糖类型进行定性分析,通过荧光检测器对 N糖含量进行定量检测。结果通过高分辨质谱、葡聚糖标准品以及 UNIFI数据库比对,各批次样品中共鉴定出 10种 N糖类型,主要是 F(6)A1、A2、F(6)A2、M5等, 10种 N糖的色谱峰峰形良好且完全分离。 F(6)A2为最主要糖型,在 6个月加速试验和 36个月长期试验的样品中,正向和倒向放置样品, F(6)A2糖型也均达 90%以上,糖型差异小,表明胶塞对全人抗 PD-L1单克隆抗体无吸附作用。结论重组全人抗 PD-L1单克隆抗体的 N糖型主要为 F(6)A2,药品的生产工艺质量和药品稳定性良好,且重组全人抗 PD-L1单克隆抗体和胶塞具有良好的相容性。
英文摘要:
      Objective To qualitatively and quantitatively analyze the N-glycan profiles for recombinant fully human anti-Pro-grammed Cell Death Ligand 1 (PD-L1) monoclonal antibody by ultra-high performance liquid chromatography-time-of-flight high reso-lution mass spectrometry (UPLC-TOF HRMS) technique. Methods A total of 11 batches of recombinant fully human anti-PD-L1 monoclonal antibody produced from March 2020 to March 2023 were selected [The antibody was provided by the Biologics (Pharmacol-ogy) Department of Anhui Institute for Food and Drug Control], including 3 batches of normal batches, 3 respective batches (uprightand inversed) of 6-month accelerated test, 1 batch (upright and inversed) of 36-month long-term test. The N-glycan profiles were quali-tatively analyzed by HRMS using the 2-aminobenzamide (2-AB) labeling method, and quantification for N-glycan was carried out on a fluorescence detector.Results Combined with 2-AB dextran calibration ladder and UNIFI databases, 10 kinds of N-glycans were iden-tified through UPLC-TOF HRMS analysis, the typical N-glycan types were F(6)A1, A2, F(6)A2, and M5. The chromatographic peaks of N-glycans were completely separated and got good peak shape. The F(6)A2 glycan was the most abundant type of N-glycan in this anti-body. The samples (upright and inversed) of 6-month accelerated test and 36-month long-term test showed that the F(6)A2 glycan allreached over 90%, and there was no difference in glycans, indicating that the rubber stopper had no absorption effect on the recombi-nant fully human anti-PD-L1 monoclonal antibody.Conclusion F(6)A2 glycan is the predominant N-glycan in the recombinant fully human anti-PD-L1 monoclonal antibody, the production process and the drug stability are relatively stable, and the recombinant fully human anti-PD-L1 monoclonal antibody has good compatibility with the rubber stopper.
