CD9 & CD63 Exosome Detection Kit
⭐️⭐️⭐️Lowest limit of detection (LOD): can detect exosomes <10^7 particles/mL
Helps you use less sample volume for more accurate exosome quantification
👍High sensitivity - 100 times higher than the competition
👍Probes designed for CD9 and CD63 on exosomes - more specific
👍High affinity (can reach >0.99)
👍Lower price
👍Exosomes only require 2.5x10^6 particles/mL - saving sample dosage
● Product Introduction
傳統外泌體定量方法的挑戰 - 早期普遍是針對外泌體的物理特性進行鑑定
(1)外泌體形態鑑定:穿透式電子顯微鏡(TEM)→設備昂貴,且需專業人員操作
(2)外泌體粒徑及濃度鑑定:奈米粒子追蹤分析(NTA)→非專一性篩選
目前發現只做物理特性的鑑定,不足以涵蓋所有品質管控的需求
隨著外泌體品質控制日益重要,外泌體表面蛋白鑑定成為關鍵需求。
外泌體蛋白表面富含
(1)參與運輸的跨膜蛋白;如CD9, CD63, CD81。
(2)熱休克蛋白HSP60、HSP70、HSP90,以及細胞特異性蛋白。
CD9、CD63和CD81是常用的外泌體表面生物標誌,但CD81最近被文獻指出,不只在外泌體上會被呈現。
