青島能源所單細胞功能分選技術取得新進展
現有基于熒光染色的活體單細胞分選技術(Fluorescence-Activated Cell Sorting; FACS)一般需要外加熒光標記，在單位時間只能獲得個別分子所代表的表型，且通常難以直接進行“原位”觀測。而基于拉曼顯微光譜技術的單細胞分選方法無需外加標記，可無損獲得整個單細胞的化
流式細胞分選的那些事
將感興趣的目的細胞分離純化出來，一直是細胞生物學中的一個重要研究手段。無論是體外刺激研究細胞因子的表達譜，還是細胞共培養檢測細胞功能，均對細胞的純度具有很高的要求。目前分離純化細胞的手段主要有兩種：MACS（magnetic-activated cell sorting），原理就是用結合了磁
流式細胞檢測
技術原理?????? 流式細胞技術（flow cytometry，FCM）是利用流式細胞儀進行的一種單細胞定量分析和分選技術。是一種在液體系統中，測定單個細胞或細胞器的生物、物理和化學特性，并根據這些特性將所需要的細胞或細胞器進行定量分析和分選的技術。它是一種可以檢測細胞或者生物學顆粒的多種特性的技

發現有望根除侵襲性乳腺癌新方法
常規化療通常不能夠根除侵襲性乳腺癌，這是因為這種癌癥在很早就發生腫瘤轉移。三陰性乳腺癌（triple-negative breast cancer, TNBC）是一種極具侵襲性的乳腺癌亞型，當前沒有靶向治療方法。最近，人們已發現癌基因MYC在TNBC中增加表達，這就為開發新的靶向治療策略來選擇性
細胞分選，不僅僅是FACS和MACS
細胞分選（cell sorting）是根據細胞的某種特性，從混合細胞樣本中挑選出特定細胞。一提到細胞分選，大家的腦海中可能馬上涌現出MACS或FACS。其實，新型的分選技術也在不斷涌現，并推動這項技術應用在更廣泛的領域。細胞分選火熱增長“細胞分選技術的應用呈爆炸式增長，在過去五年中大約翻了一番，”A
