- 背景资料
- NucView® 530 Caspase-3 Substrate, 1 mM in PBS, provides a convenient tool for detecting apoptosis in intact cells based on caspase-3/7 activity using either confocal microscopy or flow cytometry. In contrast to other fluorogenic caspase substrates or fluorescent caspase inhibitor based (FLICA) assays, NucView® caspase-3 substrates can be used to detect caspase-3/7 activity within individual intact cells without inhibiting apoptosis progression. NucView® substrates consist of a fluorogenic DNA dye coupled to the caspase-3/7 DEVD recognition sequence. The substrate, which is initially non-fluorescent, penetrates the plasma membrane and enters the cytoplasm. In apoptotic cells, caspase-3/7 cleaves the substrate, releasing the high-affinity DNA dye, which migrates to the cell nucleus and stains DNA with fluorescence. Thus, NucView® Caspase-3 Substrates are bifunctional, allowing detection of caspase-3/7 activity and visualization of morphological changes in the nucleus during apoptosis. The staining is also formaldehyde-fixable. NucView® 530 Caspase-3 Substrate stains apoptotic cell nuclei with orange fluorescence (Ex/Em 528/563 nm), for detection in the Cy®3 channel by fluorescence microscopy (Figure 2) or the PE channel by flow cytometry. NucView® 530 can be used for multi-color imaging with blue, green, or far-red fluorescent probes. Note that when excited by the 488 nm laser line, NucView® 530 also fluoresces in the FITC channel, and therefore cannot be analyzed together with green probes by flow cytometry. NucView® 530 Caspase-3 Substrate also is available as a 1 mM solution in DMSO. The substrate in PBS is formulated for use in cells that are sensitive to DMSO toxicity. In non-DMSO sensitive cell types, adding DMSO during the substrate incubation may enhance NucView® 530 staining. Biotium also offers blue fluorogenic NucView® 405 Caspase-3 Substrate, and green fluorogenic NucView® 488 Caspase-3 Substrate and kits. Cy dye is a registered trademark of GE Healthcare.
- 产品描述
- NucView®530 Caspase-3底物(PBS中1 mM)为使用共聚焦显微镜或流式细胞术基于caspase-3/7活性检测完整细胞中的细胞凋亡提供了方便的工具。与其他荧光半胱天冬酶底物或基于荧光半胱天冬酶抑制剂(FLICA)的测定相比,NucView®半胱天冬酶-3底物可用于检测单个完整细胞内的半胱天冬酶-3 /7活性,而不抑制凋亡进展。NucView®底物由与胱天蛋白酶-3 /7 DEVD识别序列偶联的荧光DNA染料组成。最初不发荧光的底物穿透质膜并进入细胞质。在凋亡细胞中,胱天蛋白酶-3 /7切割底物,释放高亲和力DNA染料,其迀移到细胞核并用荧光染色DNA。因此,NucView®Caspase-3底物是双功能的,允许检测caspase-3/7活性并可视化细胞凋亡期间细胞核中的形态学变化。染色也是甲醛固定。& nbsp; NucView®530 Caspase-3底物用橙子荧光(Ex/Em 528/563 nm)染色凋亡细胞核,用于®通过荧光显微镜(图2)在Cy 3通道中检测或通过流式细胞术在PE通道中检测。NucView®530可用于蓝色、绿色或远红色荧光探针的多色成像。注意,当被488 nm激光线激发时,NucView®530也在FITC通道中发荧光,因此不能通过流式细胞术与绿色探针一起分析。nbsp; NucView®530半胱天冬酶-3底物也可作为1 mM DMSO溶液提供。配制PBS中的底物用于对DMSO毒性敏感的细胞。在非DMSO敏感的细胞类型中,在底物孵育期间添加DMSO可增强NucView®530染色。Biotium还提供蓝色荧光NucView®405 Caspase-3底物和绿色荧光NucView®488 Caspase-3底物和试剂盒。nbsp; Cy染料是GE Healthcare的注册商标。
