| I. Background | |
抗體依賴的細胞介導的細胞毒性作用（ADCC，antibody-dependent cell-mediated cytotoxicity ）是指抗體的 Fab 段結合病毒感染的細胞或腫瘤細胞的抗原表位，其 Fc 段與殺 傷細胞（NK 細胞、巨噬細胞等）表面的 FcR 結合，介導殺傷細胞直接殺傷靶細胞，它是 抗腫瘤的治療性抗體藥物發生作用的一種作用重要機制。 傳統用于測定 ADCC/ADCP 的方法主要依賴于相關原代免疫細胞的分離、體外分化， 進而測量靶細胞的殺傷或吞噬效應。這些方法高度依賴供體原代細胞，價格昂貴且費時費 力，對原代細胞的分離分化過程對實驗操作的要求非常高，實驗失敗風險較大，由于分離 分化細胞純度問題，還存在檢測信號低以及不穩定均一的問題。另外，每次實驗的細胞供體來源可能都不一致，實驗結果可重復性較差，可能存在批次 差異。由于以上這些因素的影響，在需要高質量控制的藥物開發過程中，很難建立穩定可 靠的檢測方法。 | |
