試劑盒點
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(biāo)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(如右圖所示)。
|
|
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(xì)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(如右圖所示)。
|
|
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(如右圖所示)。
|
|
可檢測外泌體內(nèi)容物
試劑盒配套相應(yīng)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,未穿膜時只能檢測到跨膜蛋白CD9的熒光信號,穿膜后即可檢測到外泌體內(nèi)容物Syntenin的表達(如右圖所示)。
