Protocol for T-cell Adhesion Strength on Tumor Cells under Flow Conditions 流动状态下T淋巴细胞对肿瘤细胞的粘着强度分析 作者:Marie Boutet, Katarzyna Franciszkiewicz, Audrey Le Floc’h and Fathia Mami-Chouaib日期:10/20/2013,浏览量:8458,Q&A: 0
This method allows evaluating the relative adhesion strength between T lymphocytes and specific adherent target cells using a shear force in flow chambers. It is based on the measure of the resistance of conjugates formed between T cells and adherent tumor cells to shear stress in a microfluidic system. For this purpose, T cells, stained with a ...

Fluorescence Recovery After Photobleaching (FRAP) in the Fission Yeast Nucleus 裂殖酵母细胞核的荧光光漂白技术(FRAP) 作者:Petrina Delivani, Mariola R. Chacón, Britta Schroth-Diez and Iva M. Tolić-Nørrelykke日期:10/20/2013,浏览量:9254,Q&A: 0
We use fluorescence recovery after photobleaching (FRAP) to calculate the diffusion coefficient of GFP in the nucleoplasm of fission yeast. The FRAP method can be generally used to measure the mobility of proteins inside the cell or its organelles.
In our experiment we only measured the diffusion of GFP inside the nucleoplasm of fission ...

In vitro T Cell–DC and T Cell–T Cell Clustering Assays T淋巴细胞与树突细胞以及T淋巴细胞之间的体外簇集试验 作者:Audrey Gérard日期:10/20/2013,浏览量:12799,Q&A: 0
To get activated, T cells need to find their cognate antigen at the surface of an antigen-presenting cell (APC). Recognition of cognate antigen in the context of the MHC (Major histocompatibility complex) by the TCR (T-Cell Receptor) results in long lasting interactions between T cells and APCs. Subsequently, T cells form homotypic interactions ...

Surface Polysaccharide Extraction and Quantification 表面多糖提取和量化 作者:Cedric Arthur Brimacombe and John Thomas Beatty日期:10/20/2013,浏览量:16654,Q&A: 1
Gram-negative bacterial cells possess two membranes - the inner cytoplasmic membrane and the outer membrane. The two membranes are distinct in their composition; the inner membrane is composed of a phospholipid bilayer, whereas the outer membrane (OM) is composed of an asymmetrical bilayer, with the outer leaflet containing lipopolysaccharide ...

Plant viruses are strong inducers as well as targets of RNA silencing. In plants RNA silencing acts as a natural defense mechanism against viral infection and is associated with accumulation of virus-specific small interfering RNAs (siRNAs). The continuing discoveries, increasing awareness and interest in the regulatory roles of non-coding small ...

Trehalose is a nonreducing disaccharide. It is a common sugar in bacteria, fungi and yeast, where it functions as a carbon source and stress protectant. In contrast, plants, although encoding large trehalose biosynthesis gene families, contain only small amounts of trehalose. The intermediate compound of trehalose, trehalose-6-phosphate (T6P), is ...
