關於活動

細胞外囊泡及外泌體受限於偵測技術, 只能透過電子顯微鏡或是傳統的檢測方法如動態光散射（DLS）來檢測。而傳統流式細胞儀受限於300nm的偵測極限，對於大部分的細胞外囊泡特性分析造成挑戰。NTA可偵測粒徑分布及粒子濃度, 其螢光分析模式更能偵測到外泌體的生物標誌。 本次研討會由 Malvern Panalytical（台灣思百吉股份有限公司）、國立台灣大學生物技術研究中心、國立台灣大學生命科學院共同舉辦。我們也將在本次研討會中探討細胞外囊泡和外泌體之研究 Extra-cellular microvesicles and exosomes are instrumental as biomarkers for a wide range of treatments from cancer to diabetic therapies. It is noted that traditional characterisation methods of exosomes or EVs are limited. For instance, conventional flow cytometry has a lower limit in practice of some 300nm and therefore cannot see the majority of microvesicular material thought to be present. NTA offers a means by which not only can such structures be seen and concentration measured, but variations in the technique, such as fluorescence mode NTA, have allowed exosomes to be phenotyped. This multi-parameter capability, compatible with natural structures in their native environment promises to be of significant value in the elucidation of the role these structures play. Join us for our free seminar co-organised by Malvern Panalytical, National Taiwan University Biotechnology Center and National Taiwan University’s Department of Life Sciences. Our guest speakers will discuss about their research in extracellular vesicles and exosomes; namely how NTA technology is instrumental towards the classification and tracking of such nanoparticles in today’s modern medicine
