항체 등 단백질의 역상 분리에서 탁월한 성능 발휘

비다공성 ODS 컬럼인 Presto FF-C18을 사용하면, 기존의 Wide-Pore 역상 컬럼으로는 볼 수 없었던 다수의 피크가 단백질 및 단클론항체(mAb)에서 검출됩니다. 기존 컬럼에서는 넓게 뭉쳐 보이던 피크가 실제로는 여러 성분으로 이루어진 것으로 확인됩니다. 이는 단백질 폴딩 과정에서 S-S 결합 위치와 관련된 입체구조 차이를 Presto FF-C18이 변성 없이 인식하기 때문으로 추정됩니다. 아미노산 서열의 변이, 불순물, 당화(glycosylation) 역시 이러한 차이에 기여할 수 있으며, 이는 본 컬럼이 단백질의 고차구조를 검출할 수 있는 능력을 보여줍니다.

Presto FF-C18을 통해 기존 컬럼으로는 볼 수 없었던 다수의 피크를 검출할 수 있게 됨에 따라, 항체 의약품을 비롯한 단백질 치료제의 구조 분석 발전에 기여할 것으로 기대됩니다.

비다공성 ODS 컬럼 Presto FF-C18은 단백질뿐 아니라 다당류, DNA와 같은 생체분자의 역상 분리에도 뛰어나며, 합성 고분자에도 적용 가능합니다. 기존 SEC 모드로는 얻기 어려웠던 날카롭고 정량 가능한 피크를 얻을 수 있습니다. ELSD와 같은 고분자용 검출기를 함께 사용하면, 고분자 분석을 위한 새로운 역상 분리 방법을 제시할 수 있을 것으로 기대됩니다.

낮은 캐리오버 (Low Carryover)

Presto FF-C18은 의약품 LC-MS 분석에서 우수한 저캐리오버 성능을 나타냅니다. 이는 기공 내부에서 발생하는 비특이적 흡착을 방지하는 비다공성 실리카 구조에 기인하는 것으로 추정됩니다.
