如何在斑马鱼完整胚胎样本中使用RNAscope®技术进行研究

整胚原位杂交是在完整胚胎和组织中研究基因时空表达模式的有力工具。但现有的实验方法无法准确的直接检测RNA,而且操作耗时,结果和蛋白表达水平不一致。新一代原位定量杂交技术RNAscope®可以在斑马鱼整胚上实现快速高效、精准定量、特异性的多重RNA原位检测。该webinar由美国ACD公司(Advanced Cell Diagnostics, Inc., California, USA)邀请德国Münster大学细胞生物学研究所Erez Raz教授实验室两位研究员Azadeh Paksa 和 Theresa Gros介绍他们利用RNAscope®技术实现斑马鱼整胚上同时原位检测3个RNA分子进行三维荧光分析。详细介绍了实验操作过程,如何优化条件,降低信噪比以及RNAscope®技术相比传统原位杂交技术的绝对优势。

被移植的心脏如何重新跳动的?

TransMedics’ proprietary Organ Care System (OCS) is the first commercial and portable warm blood perfusion organ transport system. With the OCS, doctors are able to perform “living organ transplants,” where organs are kept warm and functioning in a controlled environment from the time they are recovered to the moment they are placed in the recipient’s body.

细胞大小究竟如何调控细胞增殖

Martin Raff (UCL) Part 1: Regulation of Cell Size

The size of an organ or organism depends mainly on the sizes and numbers of the cells it contains. In the first segment of my talk, I describe our work on cell size control in cultures of purified rat Schwann cells. Most proliferating cells grow before they divide, but it is not known how growth and division are co-ordinated to ensure that cells divide at an appropriate size. We have found that extracellular signals can control cell growth and cell-cycle progression separately and that the size of Schwann cells at division depends on the signalled rates of both cell growth and cell-cycle progression, rather than on a cell-size checkpoint that monitors cell size.

细胞数目究竟如何调控细胞增殖

Martin Raff (UCL) Part 2: Cell Number Control

In the second segment of my talk, I describe our work on cell number control in the rat oligodendrocyte cell lineage. Cell numbers depend on controls on both cell death and cell proliferation. We have found that oligodendrocytes are normally overproduced and kill themselves in large numbers in a competition for survival signals on the surface of the axons that the oligodendrocytes myelinate. Most differentiated cells, including oligodendrocytes, develop from dividing precursor cells that divide a limited number of times before they terminally differentiate, but it is not known what stops cell division and initiates differentiation. We have found that oligodendrocyte precursor cells have an intrinsic timing mechanism that helps determine when they stop dividing and differentiate. See more at http://www.ibioseminars.org

如何做一个完美的Western Blot检测

In the western blot visual protocol video, you will learn how to prepare your samples before loading them into a gel, load a gel and separate the proteins through electrophoresis, transfer your proteins from the SDS-PAGE gel onto a PVDF or nitrocellulose membrane, block the membrane, stain in Ponceau red, add the primary and secondary antibodies, and visualize your protein of interest. Additional help can be found in the support section of http://www.novusbio.com, through our live chat service, or by calling us directly to talk with our elite customer and technical service scientists.
