常见问题解答 (FAQ)

我的细胞周期数据显示单一峰而非正确的细胞周期曲线,该如何解决这个问题?

许多因素影响着细胞周期曲线的质量。细胞数、染料浓度、孵育温度、孵育时间、流速(在利用流体动力学聚焦的传统流式细胞仪上处理时)、获得细胞的总数、死细胞排除以及从数据分析中除去聚集体等,都需要在分析细胞周期时考虑到。

流式细胞仪能分析哪些细胞过程?

•钙流:每一种Oregon Green钙指示剂都可通过更高的亲和力结合胞内钙离子,提供适合很多应用的灵敏度范围。Oregon Green探针在Ca2+静息水平下发射绿色荧光;Ca2+浓度增加时,荧光强度会增加14倍。细胞通透配方(货号O6807)能加入到细胞培养基中并与流式细胞仪兼容。

•基于罗丹明的钙离子指示剂包含了大量不同的探针,用于探测Ca2+浓度的大小变化。该指示剂与钙离子结合后,会发出50倍增强的荧光。这一类波长范围的荧光可与GFP或绿色荧光染料结合,用于多重检测应用。Rhod-2, AM(货号R1245MP)专门靶向线粒体,可与流式细胞仪联用。

•膜电位:细胞凋亡初期的典型特征是线粒体紊乱,伴随着膜和氧化还原电位变化。我们提供一系列专门用于流式细胞术活细胞线粒体膜电位分析的产品,可最大限度避免影响细胞功能。对于细胞凋亡过程出现的线粒体膜电位损失,MitoProbe系列线粒体染色剂(货号M34150、M34151和M34152)可提供快速、简单和可靠的流式细胞术检测方法。MitoTracker染料(货号M7510和M7512)是用于染色活细胞内的线粒体的膜电位依赖型探针。在之后的流式细胞免疫化学、DNA末端标记,原位杂交或复染色步骤中,MitoTracker染料的染色图案全程保留。相比于只依赖线粒体膜电位的检测方法,线粒体通透性转移孔检测体系(货号M34153)可直接测定通透性转移孔开合情况。线粒体通透性转移孔(MPTP)是一个由线粒体内膜和外膜成分构成的非特异性通道。在细胞死亡过程中,此通道显现,参与线粒体成分释放。

•吞噬作用:在吞噬过程中,细胞内吞微粒(如微生物)。此过程对于免疫应答非常重要,同时对清除凋亡细胞也非常重要。研究吞噬作用的探针包括BioParticles指示剂——用荧光标记的细菌和酵母。

•使用淬灭/洗涤检测法来追踪吞噬过程能够表征简单的摄入,或利用一种pH指示剂监视吞噬途径的各个阶段。我们提供pHrodo Red或Green(货号A10010、P35361、P35364、P35365、P35366和P35367)标记的免洗检测体系和全血的免洗检测体系(货号A10025、A10026、P35381和P35382),都适用于流式细胞仪。

•pH改变:可使用荧光强度或比率计测定法测定生理学范围内的细微pH变化。pHrodo 染料(货号P35373和P35372)提供了pH2-9之间的信号强度调制,同时可以选择各种荧光波长。荧光右旋糖酐内吞示踪是分析细胞区室pH变化的常用方法。pHrodo染料的右旋糖酐偶联物(货号P35368和P10361)可用于区分从早期的核内体到溶酶体在内的各种囊泡,不需要洗涤和淬灭,是最完整的解决方案。

•活性氧:处于环境压力下的细胞通常含有超高水平的活性氧(ROS)。CellROX试剂是为检测和定量活细胞中的ROS而开发的荧光探针。这些细胞通透性试剂在还原态时不发荧光或发微弱的荧光;在被氧化后,就发出明亮的荧光且依旧位于细胞内。我们提供已通过流式细胞术验证的CellROX Green(货号C10492)CellROX Orange(货号C10493)和CellROX Deep Red(货号C10491)检测试剂盒。

流式细胞术可以进行哪些类型的细胞健康和活力检测?

可以通过流式细胞仪完成以下细胞健康和活力检测:

细胞凋亡检测:

细胞膜不对称性:膜联蛋白V是结构相关蛋白家族一员,其可以在Ca2+存在的情况下结合磷脂。膜联蛋白V可结合多种磷脂,但是对磷脂酰丝氨酸表现出高度的亲和性。磷脂酰丝氨酸主要存在于细胞膜的内部小叶上;然而,在细胞凋亡早期,观测到磷脂酰丝氨酸转移到外部小叶。这个转移使得在含有Ca2+孵育缓冲液存在的情况下,磷脂酰丝氨酸可与膜联蛋白V结合。凋亡中的细胞可以用膜联蛋白V染色,而正常细胞不会被染色。多种偶联不同荧光基团的膜联蛋白V可供选择。

线粒体健康:细胞凋亡早期的典型特征是线粒体紊乱,同时伴随膜和氧化还原电位改变。我们独家提供了大量可通过流式细胞术分析活细胞内的线粒体活性,同时可最大限度避免细胞功能损伤的荧光探针。

线粒体染色的MitoProbe系列染料(MitoProbe DiOC2(3) 检测试剂盒,货号 M34150;MitoProbe JC-1检测试剂盒,货号M34152;MitoProbe DiIC1(5) 检测试剂盒,货号M34151)为检测细胞凋亡过程出现的线粒体膜电位损失提供了快速、简单和可靠的流式细胞术检测手段。

半胱天冬酶活性: CellEvent Caspase-3/7 Green 流式细胞检测试剂盒(货号C10427)支持对凋亡细胞中活化的caspase-3和 caspase-7进行流式细胞术检测。该试剂盒包含新型荧光底物CellEvent Caspase-3/7 Green检测试剂和SYTOX AADvanced死细胞染色剂,可靶向识别活化的caspase-3和caspase-7的序列。

DNA片段化:细胞凋亡后期的特征是核形态改变,包括DNA片段化、染色质凝缩、核膜降解,核起泡以及DNA链断裂。凋亡过程中DNA片段出现DNA链断裂,可以通过TUNEL(末端脱氧核苷酸转移酶dUTP缺口末端标记)检测进行分析。APO-BrdU TUNEL检测(货号A23210)是一种双色检测方法,可通过成像或流式细胞术标记DNA断裂和细胞总DNA,检测细胞凋亡情况。

核染色质凝缩:细胞凋亡后期的特征是核形态改变,包括DNA片段化,染色质凝缩,核膜降解,核起泡以及DNA链断裂。凋亡的细胞表现出核染色质凝结增加。由于核染色质凝结,细胞透过性核酸染色剂发出较高的荧光,从而能够结合传统死细胞染色剂来区分凋亡细胞。

Vybrant细胞凋亡检测试剂盒#5,Hoechst 33342/Propidium Iodide(货号V13244)基于凋亡细胞染色质的压缩状态的荧光检测,为凋亡提供了一个快速和方便的检测手段。染色质凝结&膜渗透死细胞凋亡试剂盒包含Hoechst 33342、YO-PRO-1以及PI染料, 用于流式细胞仪(货号V23201)检测凋亡细胞中核染色质凝结和质膜通透性的变化。

细胞周期分析:

活细胞检测: Vybrant DyeCycle系列染料为活细胞周期分析提供了稳定的低毒性荧光染料,提供405 nm(货号V35003)、488 nm (货号V35004)、532 nm(货号V35005)或 633 nm(货号V10309和V10273)三种激发峰选择。染料毒性低,染色的细胞可储存和培养,或进行功能分析。

固定细胞检测:用FxCycle Violet染色剂(货号F10347)、SYTOX AADvanced 死细胞染色试剂盒(货号S10349)或FxCycle Far Red染色剂(货号F10348)分析细胞周期,为简单固定的细胞周期分析提供了多色选择。

细胞增殖:

染料稀释检测细胞增殖:染料稀释检测细胞增殖依赖细胞膜透过性荧光分子。染料进入到细胞后,共价结合蛋白质的氨基基团,导致染料长期保留在细胞中。通过随后的细胞分裂,每个子代细胞大约会分到亲代一半的荧光。采用流式细胞仪对细胞群的荧光强度进行分析,可以某个细胞或细胞群自标记之后的增殖情况,判定其传代次数。CellTrace荧光染色剂可在不影响细胞形态和生理功能的条件下,在体内或体外追踪传代情况。目前尚未发现该染色剂对细胞增殖活性或细胞生物学功能有影响。染色后,染料可在细胞内稳定保留若干天。可用于流式细胞仪的试剂盒包括CellTrace CFSE细胞增殖试剂盒(货号No. C34554)CellTrace Violet细胞增殖试剂盒(货号 C34557)和CellTrace Far Red细胞增殖试剂盒(货号 C34564)。

DNA合成检测:测定新合成的DNA是准确分析某个细胞或细胞群细胞增殖情况的方法。基于DNA合成的细胞增殖检测可根据掺入的修饰核苷,测定DNA合成速率。Click-iT Plus EdU细胞增殖检测利用了click化学试剂和修饰的核苷EdU,为BrdU染色提供了出色的替代方法,可用于检测和定量新合成的DNA数量。Pacific Blue(货号C10636)、Alexa Fluor 488(货号C10632和C10633)和Alexa Fluor 647(货号C10634和C10635)可用于Click-iT Plus EdU细胞增殖检测。

活力检测:

死细胞很容易与很多试剂非特异性结合,从而给出假阳性结果。因此,从流式细胞仪数据中排除死细胞,是有助于确保结果和分析准确性的关键步骤。

不能固定膜通透染色剂:SYTOX死细胞染色剂(货号S34857、S34860、S34861、S34859和S34862)不能穿过完整的细胞膜,与dsDNA结合后发出更强的荧光,从而成为我们最明亮的几种死细胞染色剂之一。非细胞通透性的经典DNA结合染料包括碘化丙啶(货号P21493)和7-AAD(货号A1310)。这两种染料已经被广泛用于流式细胞仪活性分析。CellTrace钙黄绿素AM染料可被动运输进入到贴壁和非贴壁细胞。这些细胞通透性酯酶底物可作为测定酶活性(激发荧光的必要条件)和细胞膜完整性的(在胞内保留荧光产物的必要条件)的活力探针。目前供应的蓝色(货号 C34853)、紫色(货号C34858)和绿色(货号C34852)荧光染料是活细胞短时染色的理想染料,且可用于多重流式细胞术试验。

可固定细胞活性染色剂:LIVE/DEAD可固定死细胞染色剂是可固定的细胞活性染料,有助于准确评估固定和/或通透后样品中细胞活性。LIVE/DEAD固定死细胞染色试剂盒基于荧光活性染料与细胞蛋白(胺基)的反应。这些染料不能透过活细胞膜,因此仅仅细胞表面蛋白可和染料反应,导致染色暗淡。活性染料可以透过死细胞损毁的细胞膜,将内部和外部的胺基染色,导致更加强烈的染色效果。LIVE/DEAD固定死细胞染色试剂盒可提供八单通道颜色,适用于三种包装规格的UV、405、488、532、561或633 nm激光,可满足您的试验需要。

My cell cycle data show a single peak, not a proper cell cycle profile. How can I fix this?

There are several factors that contribute to the quality of the cell cycle profile. Cell number, dye concentration, incubation temperature, incubation time, flow rate (on a traditional flow cytometer utilizing hydrodynamic focusing), total number of cells acquired, elimination of dead cells, and removal of aggregates from data analysis should all be considered when analyzing the cell cycle.

What cellular processes can be analyzed with a flow cytometer?

-Calcium flux: Each of the Oregon Green calcium indicators binds intracellular calcium with increasing affinity, providing a sensitivity range to match many applications. Oregon Green probes emit green fluorescence at resting levels of Ca2+ and increase their fluorescence intensity 14-fold with increasing Ca2+ concentration. The cell-permeant formulation (Cat. No. O6807) can be loaded in cell media and is compatible with flow cytometry.
-Rhodamine-based calcium indicators comprise a range of probes for large or small changes in Ca2+ concentration. They exhibit a 50-fold increase in fluorescence upon calcium binding and offer a range of wavelengths that can be used in conjunction with GFP or green-fluorescent dyes for multiplexing. Rhod-2, AM (Cat. No. R1245MP), in particular, localizes to mitochondria and can be used with flow cytometry.
-Membrane potential: A distinctive feature of the early stages of apoptosis is the disruption of the mitochondria, including changes in membrane and redox potential. We offer a range of products specifically designed to assay mitochondrial membrane potential in live cells by flow cytometry, with minimal disruption of cellular function. The MitoProbe family of mitochondrial stains (Cat. Nos. M34150, M34151, and M34152) provide quick, easy, and reliable flow cytometric detection of the loss of mitochondrial membrane potential that occurs during apoptosis. MitoTracker dyes (Cat. Nos. M7510 and M7512) are membrane potential-dependent probes for staining mitochondria in live cells. The staining pattern of MitoTracker dyes is retained throughout subsequent flow cytometry immunocytochemistry, DNA end labeling, in situ hybridization, or counterstaining steps. The Mitochondrial Permeability Transition Pore Assay (Cat. No. M34153) provides a more direct method of measuring mitochondrial permeability transition pore opening than assays relying on mitochondrial membrane potential alone. The mitochondrial permeability transition pore (MPTP) is a non-specific channel formed by components from the inner and outer mitochondrial membranes, and appears to be involved in the release of mitochondrial components during cell death.
-Phagocytosis: In phagocytosis, cells internalize particulate matter such as microorganisms, and this process is important for immune responses and during the clearance of apoptotic cells. Probes for studying phagocytosis include BioParticles indicators—bacteria and yeast labeled with fluorescent dyes.
-Tracking phagocytosis using a quench/wash-based assay can report on simple uptake, or a pH indicator can be used to monitor stages in the pathway. We have no-wash assays labeled with pHrodo Red or Green (Cat. Nos. A10010, P35361, P35364, P35365, P35366, and P35367) and no-wash assays for whole blood (Cat. Nos. A10025, A10026, P35381, and P35382), all suitable for flow cytometry.
-pH changes: Sensitive pH determinations can be made in a physiological range using either fluorescent intensity or ratiometric measurements. pHrodo dyes (Cat. Nos. P35373 and P35372) provide signal intensity modulation from pH 2 to pH 9 and with a choice of fluorescent wavelengths. Tracking internalization of fluorescent dextran is a routine method for analyzing pH changes in cellular compartments. Dextran conjugates of pHrodo dyes (Cat. Nos. P35368 and P10361) provide the most complete solution by allowing discrimination of vesicles from early endosomes to lysosomes, with no quench or wash required.
-Reactive oxygen species: Cells that are environmentally stressed usually contain greatly increased levels of reactive oxygen species (ROS). CellROX reagents are fluorogenic probes developed for the detection and quantitation of ROS in live cells. These cell-permeant reagents are non-fluorescent or very weakly fluorescent in the reduced state; however, when oxidized, they become brightly fluorescent and remain localized within the cell. We offer CellROX Green (Cat. No. C10492), CellROX Orange (Cat. No. C10493), and CellROX Deep Red (Cat. No. C10491) Assay Kits validated for flow cytometry.
