生物通主辦的“2021生命科學十·大創(chuàng)新產(chǎn)品”于2022年1月正式揭曉,Quantum Design中國·新引進的NanoView R200全自動外泌體熒光檢測分析系統(tǒng),憑借其*的設計理念及·越的性能,,榮獲“2021生命科學十·大創(chuàng)新產(chǎn)品”!
“生命科學十·大創(chuàng)新產(chǎn)品”是生物通歷經(jīng)10余年打造的生命科學科學儀器行業(yè)·進,、創(chuàng)新的獎項之,。至今已舉辦十四屆。本次評選共有28臺儀器參選,,經(jīng)過評審家嚴格篩選以及廣大科研用戶的投票評比,,終評選出10·大創(chuàng)新產(chǎn)品。該獎項致力于讓大家了解生命科學發(fā)展的新方向,,也希望新穎的產(chǎn)品能激發(fā)研究者的靈感,,推動科研進程,助力科研學者早日攀上科學研究的高峰,!
全自動外泌體熒光檢測分析系統(tǒng)ExoView是美國NanoView Biosciences于2018年研究推出的,,該系統(tǒng)經(jīng)推出,便引起了外泌體域科研工作者的廣泛關(guān)注,。僅兩年已有100多個實驗室采用該技術(shù),,發(fā)表文獻近百篇,刊載在Cell, Cell Biology, Journal of Extracellular Vesicles等期刊,。ExoView的精準表征,,為科學家提供了種無須純化即可直接對血漿、血清,、尿液,、培養(yǎng)基中的外泌體進行表征分析的新方法。能夠提供單個外泌體水平下的全·方位外泌體表征信息(包括粒徑大小,、分布,、計數(shù)、攜帶蛋白表達與生物標志物(CD9,,CD81,,CD63等)共定位等),以及多層次和全方面的外泌體測量解決方案,。能夠幫助科學家更深入地了解外泌體與疾病之間的關(guān)系,,助力疾病診斷和新藥開發(fā)。
ExoView® R200全自動外泌體熒光檢測分析系統(tǒng)勢包括:
• 異性捕獲:芯片上可包被多達6 種捕獲抗體,,異性捕獲含定蛋白標記物的外泌體,。
• 對陽性外泌體計數(shù):芯片捕獲外泌體后,可通過單粒子干涉反射成像傳感器(SP-IRIS)技術(shù)直接檢測樣品中外泌體的數(shù)量,。
• 單個外泌體蛋白共定位分析:檢測每個外泌體的熒光信號并進行統(tǒng)計,,可獲得熒光共定位信息,用于分析樣品中不同表型外泌體的比例。
• 無需純化:使用抗體捕獲模式,,防止樣品中雜質(zhì)影響結(jié)果,,可直接檢測血液、尿液和細胞培養(yǎng)液中的外泌體,,未純化樣品的測量結(jié)果與純化后基本致,。
• 粒徑分辨率高:高精度SP-IRIS技術(shù),可檢測≥50 nm的外泌體,,測量結(jié)果與電子顯微鏡檢測結(jié)果基本致,,并統(tǒng)計生成外泌體的粒徑分布結(jié)果。
• 可檢測外泌體內(nèi)容物:試劑盒配套相應的穿膜劑,,可穿透外泌體并對外泌體內(nèi)容物進行染色并檢測,,如下圖所示,Non-permeabilized時只能檢測到跨膜蛋白CD9的熒光信號,, Permeabilized后即可檢測到外泌體內(nèi)容物(如PD-L1、P-tau等)的表達,。
