Follow the system installation instructions carefully and in the specified order. The software must be installed on the computer before connecting the USB cable. 2.1 Facilities Requirements Facilities requirements for the alpha-SE system are listed in Table 2-1 and the system dimensions are given in Fig. 2-1. As shown in Fig. 2-2, the alpha-SE tool requires a clear work area of 20 by 18 inches (500 by 460 mm), excluding the operator computer. 2.2 Unpacking the Hardware Opening the Shipping Container Move the alpha-SE shipping container to the area where the tool will be installed. Open the container and remove the top and side pieces of packing foam. Carefully remove all smaller components from the shipping container, verifying that you received all components, as shown in Fig. 2-3. Finally, remove the alpha-SE ellipsometer and position it on your clear 20” by 18” (510 by 460 mm) workspace. Caution: The alpha-SE ellipsometer without sample chuck weighs approximately 37 lbs. (16 kg.). Please find an assistant to lift the alpha-SE unit out of the shipping carton and on to clear work surface. 展开

荧光显微镜dm啥意思

荧光显微镜DM啥意思:深入解析其在科学研究中的应用与重要性

荧光显微镜DM是现代生物学、医学及材料科学研究中不可或缺的工具。随着显微技术的不断发展,荧光显微镜作为一种高灵敏度的观测仪器,已经广泛应用于细胞学、分子生物学等多个领域。DM代表的具体含义通常与该显微镜的品牌、型号及其功能密切相关。本文将详细解释“荧光显微镜DM”这一术语的背景,阐述它在科研中的具体应用,并探讨其在未来技术进步中的发展方向。

荧光显微镜DM的含义

“DM”通常是指一种特定系列的荧光显微镜产品,这一系列显微镜大多由知名显微镜制造商如Leica等推出,作为其产品命名的一部分。例如,Leica DM系列显微镜中,“DM”可能代表的是“Digital Microscope”(数字显微镜)或其他与设备相关的命名方式。这类显微镜通过荧光标记的技术,能够观察到生物样本中无法通过普通显微镜查看到的细微结构。

荧光显微镜利用荧光标记物来标识特定分子或细胞组件,激发后释放特定波长的荧光信号,从而揭示细胞内部的各种活动和结构。不同的荧光染料可以针对不同的生物分子,使得研究人员能够精确地观察细胞内特定目标分子的动态变化。

荧光显微镜DM的应用领域

荧光显微镜DM广泛应用于生物学、医学、环境科学等领域。在细胞学和分子生物学的研究中,荧光显微镜能够帮助研究人员了解基因表达、蛋白质定位及细胞内动态变化。在医学研究中,它被广泛应用于肿瘤学、神经科学、免疫学等领域,通过观察病理切片或活体细胞的标记,深入分析疾病的发生机制和发展过程。

在材料科学领域,荧光显微镜还能够用于观察纳米材料的结构及性能,尤其是在新材料的研发和表面分析中,发挥着至关重要的作用。

技术优势及发展前景

荧光显微镜DM技术的核心优势在于其高灵敏度和高分辨率。与传统显微镜相比,荧光显微镜可以观察到非常微小的结构,并且能够进行实时动态观测。在实验室中,它的非侵入性观察特性使得活细胞观察成为可能,这对于生物学的长期跟踪实验至关重要。

随着荧光显微镜技术的进步,未来的DM系列产品将继续向高分辨率、更高灵敏度、更的多通道观测发展。配合计算机图像处理技术,荧光显微镜的成像精度和自动化水平将进一步提升,为科研提供更为强大的技术支持。

总结

荧光显微镜DM作为现代显微技术的重要组成部分,不仅在生物学、医学等领域发挥着重要作用,而且随着技术的进步,逐步成为多学科交叉领域研究的重要工具。通过荧光显微镜,研究人员能够深入探索生命现象的本质,为医学诊断、疾病以及新材料研发提供重要数据支持。随着科技不断发展,荧光显微镜DM必将迎来更为广阔的应用前景,成为科学研究中不可或缺的利器。

To show that HAX-1 degradation is part of the apoptotic process and any involvement Omi may have, we used the ucf-101 inhibitor. ucf-101 is a specific inhibitor of the proteolytic activity of Omi and has been described previously (13). When HK-2 cells were treated with cisplatin in the presence of ucf-101, the percentage of apoptotic cells decreased and the inhibitor significantly blocked HAX-1 degradation. This effect was more pronounced when a higher concentration of the inhibitor was used. To confirm the specificity of the inhibitor in this system and exclude the possibility that another protease rather than Omi is involved in HAX-1 cleavage, we used cell lines derived from mnd2 mice (9). The parent cell line (mnd2-MSCV) derived from mouse embryo fibroblasts has no detectable Omi proteolytic activity (9). The same cell line has been transfected with wild type human Omi cDNA (mnd2-MSCV-Omi) and expresses high levels of active Omi protein (14). We found that in mnd2-MSCV cells, when induced to undergo apoptosis with various stimuli, the number of apoptotic cells was very low. Furthermore, no detectable cleavage of HAX-1 was observed. This is in contrast with the mnd2-MSCV-Omi cells where apoptosis was robust, and HAX-1 levels were inversely proportional to the degree of apoptosis. This experiment clearly shows that Omi is solely responsible for HAX-1 cleavage, which is essential for apoptosis under the conditions used in these experiments. HAX-1 subcellular localization depends on cell type (21, 30) and has been reported to be present in the mitochondria, cytoplasm, or plasma membrane (10, 21, 22, 30). We performed subcellular fractionation to investigate where HAX-1 cleavage by Omi takes place. We found that, in HEK293 cells, HAX-1 was predominantly present in the mitochondria, and this localization did not change in response to apoptotic stimuli. This suggests that Omi can initiate apoptosis in the mitochondria by cleaving HAX-1 protein. This is in accord with a recent study that shows Omi can induce apoptosis in human neutrophils treated with TNF- without being released from the mitochondria (7). Although several studies clearly define HAX-1 as an anti-apoptotic protein, the mechanism of its function is unknown. HAX-1 has sequence similarity to Bcl-2 family of proteins (10, 22). 展开

During the preparation of the nano-products, these nano-units, such as nanoparticles, nanoclusters, nanowires and nanorods, can also self-assemble into the novel structural aggregates by several routes, including electron irradiation deposition [19], chemical vapor deposition [20], laser vaporization-condensation [21], charge transferring [22], an organic reagent-assisted method [23], solution-liquid-solid method [24] and catalytic vapor-liquid-solid growth [25]. With these routes, various nanoscale or microscale aggregates can demonstrate novel architectures, including tree-like, web-like, spherical, nanowire-like, network and fishbone-like aggregates. As a well-known method for producing the nanocapsules, however, arc-discharge has been rarely used to synthesize the aggregates self-assembled by the nanocapsules prepared simultaneously in arc-discharge. Nevertheless, it is possible that the arc-discharge can be developed into a new way to synthesize the aggregates. In the present work, we utilized arc-discharge technique with modified strategies, involving changing the hydrogen pressure, introducing gadolinium - aluminum alloy ingot as the anode and adjusting the elements percent of the anode according to their evaporation pressure, to synthesize a new type of nanocapsules, with intermetallic compound GdAl2 as core and amorphous Al2O3 as shell, which enlarge the family of the magnetic nanocapsules. At the same time, the regularly aligned three-dimensional macro-aggregates self-assembled by the nanocapsules without any template and catalyst were simultaneously synthesized in arc-discharge process. 展开

Attaching the Sample Chuck You will need a #2 Phillips screwdriver for this step. Following the details shown in Fig. 2-4, install the sample chuck by first aligning the pins on the bottom of the sample chuck with the receptacles on the alpha- SE base. Then tighten the upper two captive thumb screws. Next, use the Phillips screwdriver to tighten the lower two captive screws. Don’t over tighten the screws! It will make it difficult to remove them in the future; just ensure that the screws are snug. Finally, connect the vacuum line from the sample chuck to the vacuum fitting on the alpha-SE base. Releasing the Z-stage Shipping Lock To access the Z-stage shipping lock, first loosen the captive screw on the lamp/shipping lock access door, then open the access door by rotating 180°, as shown in Fig. 2-5. To release the Z-stage shipping lock, stand in front of the ellipsometer and use your left hand to balance the weight of the Z-stage (you will feel it lift up slightly). It will be difficult to release the shipping lock if you apply too much or not enough upward force. Next, use your right hand to move the shipping lock to the operating position (to the right, see Fig. 2-6). If the lock is hard to move, you can use a tool to gain more leverage. The shipping lock will move about 1/3” [8mm] to the right. Checking the Lamp Check that the QTH lamp in fully seated in the lamp housing. The lamp is located behind the actuator screw (see Fig. 2-6) and has two white wires protruding from the back of the lamp. Simply push down on the lamp ensuring that the lamp is fully seated in the lamp housing. Rotate the lamp/shipping lock access door to the closed position and hand tighten the captive screw. 拒绝翻译软件,翻译软件我自己也会用 不是用翻译软件我就看不懂,只是,上来找人翻译就是希望翻译出比较容易看懂,不需要自己对照就可以看的说明书,如果用翻译软件,根本就词不达意,还是要自己对着原文件核实 既然用了那么多积分,就希望有相当的成果,如果用翻译软件混积分,那就是人品问题了 还有,某些人不要不懂乱说混积分 展开
