全光譜熒光檢測

Countess® II FL全自動(dòng)細(xì)胞計(jì)數(shù)儀具有兩路熒光通道。其所采集的熒光色通過插入單獨(dú)的光立方進(jìn)行測定。Countess® II FL全自動(dòng)細(xì)胞計(jì)數(shù)儀提供有超過15種光立方可供選擇，檢測不受表達(dá)GFP和RFP的細(xì)胞的限制。對于轉(zhuǎn)染了RFP表達(dá)載體，和藍(lán)色核復(fù)染的細(xì)胞，，您是否希望測定其轉(zhuǎn)染效率？沒問題！您只需加入和RFP和DAPI光立方，即可對整個(gè)細(xì)胞群之中表達(dá)RFP融合的細(xì)胞進(jìn)行高效地計(jì)數(shù)，同時(shí)還可精確地測定轉(zhuǎn)染效率。

通過兩種顏色熒光進(jìn)行細(xì)胞計(jì)數(shù)。將10 μL采用CellLight® Histone 2B-RFP轉(zhuǎn)導(dǎo)并采用NucBlue® Live ReadyProbes® 試劑染色的Hela細(xì)胞加入到腔室載玻片上，然后插入到配備了DAPI和RFP光立方的Countess® II FL全自動(dòng)細(xì)胞計(jì)數(shù)儀上。新Countess® II FL全自動(dòng)細(xì)胞計(jì)數(shù)儀的分割和計(jì)數(shù)算法可以根據(jù)細(xì)胞的熒光性質(zhì)對其進(jìn)行計(jì)數(shù)。在本實(shí)驗(yàn)中，細(xì)胞群之中86%的Hela細(xì)胞被

Countess® II FL全自動(dòng)細(xì)胞計(jì)數(shù)儀所采用的EVOS®光立方。

Countess® II FL全自動(dòng)細(xì)胞計(jì)數(shù)儀的熒光檢測技術(shù)的核心是的EVOS® LED光立方。每個(gè)光立方含有一個(gè)LED、發(fā)光光學(xué)器件和濾光片。光立方具有插拔功能，可由用戶更換，并通過Countess®系統(tǒng)進(jìn)行自動(dòng)配置。這些類型廣泛的光立方為眾多熒光研究應(yīng)用（如細(xì)胞活力分析）提供了更大的靈活性。

The Countess® II FL Automated Cell Counter is a benchtop instrument designed and manufactured by Invitrogen, which performs cell counting and viability measurements in concert with trypan blue stain.  The Countess™ provides fast, easy and accurate cell counting without using a hemocytometer, thus eliminating the tedium and subjectivity of manual cell counting.
 
GIBCO® brand TrypLE™ Select and TrypLE™ Express are recombinant serine protease enzymes of high purity, which contain no components of animal origin.  TrypLE is designed to remove adherent cells from the surface of plastic flasks and plates in a gentler manner.  In addition, it is room temperature stable and a direct replacement for trypsin.

• This protocol details the procedure for obtaining accurate cell counts using TrypLE cell dissociation products with the Countess® II FL Automated Cell Counter.
