[Application Note]
VISQUE InVivo imaging system 을 이용한 Pharmacokinetics 및 Biodistribution 분석
형광 영상 촬영 기법을 이용하여 이제는 소동물에 주입된 세포, 항체, 엑소좀, 신약후보물질 등의 real-time Biodistribution 과 kinetics 를 분석할 수 있습니다.
실험 방법
Exosome에 ICG를 결합하여 10주 된 Nude mouse(BALB/cAJcl-nu/nu)의 미정맥에 정맥주사(intravenous injection)하여 Time-laps 촬영을 하였습니다.
실험 결과
단순 ICG는 미정맥 주사 후, 수 초 이내에는 혈관으로 circulation 하여 수분 이내에 간, 소장 등 각 장기로 순차적으로 이동하며, 약 15분 이후가 되면 방광에 모이게 됩니다. ICG 는 몸 안에서 반감기가 아주 짧아서 주입 후 약 30분 정도가 지나면 방광 이외에는 다른 장기에는 거의 남아있지 않습니다. 반면에 단순 ICG 분자가 아닌 ICG-tagging probe complex 를 연구자가 제작해서 혈관 내로 주입할 경우, tagging probe 가 특정 분자에 binding 했다면 주입 후 30분이 지나도 blood circulation으로 washout 되지 않고 목표 지점에 남아 있게 됩니다.
VISQUE InVivo imaging system을 이용한
brain blood flow imaging 및 real-time image 분석
VISQUE 의 전용 소프트웨어인 Clevue를 이용하여 형광물질이 지난 혈관의 맵을 만들고, 혈류량, 혈류 속도 등을 실시간으로 촬영하고 분석할 수 있게 되었습니다. 노화, 치매 등 혈관과 관련된 연구에 in-vivo 이미징 기법을 적용해 볼 수 있습니다.
실험 방법
ICR mouse 의 MCAO (중간대뇌동맥결찰) 수술 1일 후, ICG 를 미정맥 주입하고 실시간 촬영한 영상입니다.
실험 결과
Mouse 두개골을 제거하지 않은 상태로 brain 혈관에 따른 혈류의 속도와 혈류량을 분석할 수 있습니다. 손상된 뇌혈관이 특정 조치에 따라 시간이 지나 회복되는 것을 관찰할 수 있습니다.
