Sample preparation in the Era of “analytical arms race” 가장 이상적인 시료 전처리 시스템의 조건 지질층과 molecular complexes가 잘 분리되야 함, but 단백질, DNA, RNA의 공유결합에 영향을 주면 안됨. 시료 전처리 중 한결같은 에너지가 제공되어야 함. 지질 단백질, 핵산의 구분이 용이하여야 함. 추출 buffer에 친화적이어야 함. Cross-contamination을 방지할 수 있어야 함 진행되는 동안 안정적으로 시료 enclosed 유지하여야 함 정확하게 온도를 제어하여야 함 Frozen samples을 즉시 적용가능해야 함 분석을 위한 실험방법과 잘 matching 되는지를 충족시켜야 함. Well-defined experimental goal and well-prepared sample are the foundation of success.
