Quantification of Fatty Acids in Mammalian Tissues by Gas Chromatography–Hydrogen Flame Ionization Detection 气相色谱-氢火焰离子化检测法测定哺乳动物组织中的脂肪酸 作者:Fumie Hamano, Suzumi M Tokuoka, Tomomi Hashidate-Yoshida, Hideo Shindou, Takao Shimizu and Yoshihiro Kita日期:05/05/2020,浏览量:1316,Q&A: 0
In mammalian organisms, fatty acids (FAs) exist mostly in esterified forms, as building blocks of phospholipids, triglycerides, and cholesteryl esters, while some exist as non-esterified free FAs. The absolute quantification of FA species in total lipids or in a specific lipid class is critical in lipid-metabolism studies. To quantify FAs in ...

Colorimetric RhoB GTPase Activity Assay 比色法测定RhoB-GTPase活性 作者:Kossay Zaoui and Stephanie Duhamel日期:05/05/2020,浏览量:1583,Q&A: 0
The Ras homologous protein (Rho) GTPase subfamily, including RhoA, RhoB, and RhoC are small molecules (~21 kDa) that act as molecular switches in a wide range of signaling pathways to orchestrate biological processes associated with both physiological and tumorigenic cellular states. The Rho GTPases are crucial regulators of actin cytoskeleton ...

Evaluation of B Cell Proliferation in vivo by EdU Incorporation Assay 通过EdU掺入法评估体内B细胞增殖 作者:Adi Biram and Ziv Shulman日期:05/05/2020,浏览量:1259,Q&A: 0
Generation of antibodies is crucial for establishing enduring protection from invading pathogens, as well as for maintaining homeostasis with commensal bacteria at mucosal surfaces. Chronic exposure to microbiota- and dietary- derived antigens results in continuous production of antibody producing cells within the Peyer’s patch germinal center ...

Assessing in vitro and in vivo Trogocytosis By Murine CD4+ T cells 用小鼠CD4+T细胞评价体内外胞啃作用 作者:Jim Reed and Scott A. Wetzel日期:05/05/2020,浏览量:1139,Q&A: 0
Recognition of antigens by lymphocytes (B, T, and NK) on the surface of an antigen-presenting cell (APC) leads to lymphocyte activation and the formation of an immunological synapse between the lymphocyte and the APC. At the immunological synapse APC membrane and associated membrane proteins can be transferred to the lymphocyte in a process called ...

HIV-CRISPR: A CRISPR/Cas9 Screening Method to Identify Genes Affecting HIV Replication HIV-CRISPR:一种CRISPR/Cas9筛选HIV复制相关基因的方法 作者:Ferdinand Roesch and Molly OhAinle日期:05/05/2020,浏览量:1230,Q&A: 0
Screening with CRISPR/Cas9 technology has already led to significant discoveries in the fields of cancer biology, cell biology and virology. Because of the relatively low false discovery rates and the ability to perform high-throughput, pooled approaches, it has rapidly become the assay of choice for screening studies, including whole-genome ...

Viral Double-Stranded RNA Detection by DNase I and Nuclease S1 digestions in Leishmania parasites 在利什曼原虫中利用DNase I和 Nuclease S1酶解进行病毒双链RNA鉴定 作者:Nathalie Isorce and Nicolas Fasel日期:05/05/2020,浏览量:830,Q&A: 0
Many RNA viruses are found in protozoan parasites. They can be responsible for more serious pathology or treatment failure. For the detection of viral double-stranded RNA (dsRNA), sequence-dependent and -independent methods are available, such as quantitative real-time PCR and immunofluorescence, dot blot, ELISA or sequencing. The technique ...

Kinases and ATPases perform essential biological functions in metabolism and regulation. Activity of these enzymes is commonly measured by coupling ATP consumption to the synthesis of a detectable product. For most assay systems the ATP concentration during the reaction is unknown, compromising the precision of the assay.
