Abstract
본 발명에서는 MOG-IgG에 특이적으로 결합하는 2차 항체로서 형광-결합된 IgG (H+L)을 사용하는 경우 CBA-IF 및 CBA-FACS 결과 사이에 강한 양의 상관 관계가 있고, 기존의 IgG1 (Oxford) CBA-IF와 비교하여서도 약 98 %의 높은 일치율을 나타냄을 확인하였으며, 특히 본 발명의 방법은 MOG를 발현하는 안정한 세포주(stable cell line)를 제작함으로써 반복적인 형질 감염(transfection)이 요구되지 않으며, 2차 항체 IgM과 교차반응(cross reaction)을 나타내지 않아 특이도가 높고 보다 명확한 형광 신호를 얻을 수 있는 장점이 있다.
Description
도 2의 A는 CNS 염증성 질환 환자 및 대조군(HC)의 혈청에 대해 각각 2차 항체 IgG (H+L), IgG1-Fc 및 IgM를 사용하여 CBA-FACS를 수행한 결과를 나타내며, 도 2의 B는 IgG (H+L), IgG1-Fc에 대한 각각의 ROC 곡선 및 MFI 비율에 대한 곡선 아래 면적(AUC)을 계산한 결과를 나타낸 것이다.
도 3은 다양한 CNS 염증성 질환 환자에 대해 ROC 곡선에서 최적의 컷오프를 계산하고, 각 질환별 MFI 비율의 분포를 나타낸 것이다.
도 4는 40명의 MOG-IgG 혈청 양성 환자의 IF 점수 및 MFI 비율로부터 CBA-IF 점수와 CBA-FACS의 상관 관계를 확인한 결과를 나타낸 것이다.
도 5의 A 및 B는 각각 FL-MOG로 형질 감염된 FL-MOG + HEK293 세포주 및 EV-형질 감염된 HEK293 세포주에서 형광 신호를 관찰한 결과, 및 2차 항체 IgG (H+L), IgG1-Fc 및 IgM를 사용하여 CBA-FACS를 수행한 결과를 나타낸 것이다.
