Binding Affinity Measurement of Antibodies from Crude Hybridoma Samples by SPR 表面等离子共振法测定原初杂交瘤样本中抗体与抗原的结合亲和力 作者:Dorin Mlaki Ndao, David T. Hickman, María Pilar López-Deber, Aurélien Davranche, Andrea Pfeifer and Andreas Muhs日期:11/05/2014,浏览量:13768,Q&A: 0
Surface Plasmon Resonance (SPR) is widely used to generate kinetic and affinity information on specific interactions between biomolecules. This technique is label-free and monitors the binding event in real-time. It is generally used for characterization of monoclonal antibody - antigen interactions. This protocol describes specifically the use of ...

Isolation and in vitro Activation of Mouse Peyer’s Patch Cells from Small Intestine Tissue 小鼠小肠派尔结的淋巴结细胞分离和体外激活 作者:Claudia Pastori and Lucia Lopalco日期:11/05/2014,浏览量:16733,Q&A: 0
The lumen of gastrointestinal tract is exposed to several potentially pathogenic microorganisms, thus it is extremely relevant to understand how immunosurveilance can be established. Peyer’s Patches (PPs) are oval or round lymphoid nodules that protrude from the outer wall of the ileum portion of small intestine. PPs contain a high percentage of B ...

Measurement of Proton-driven Antiport in Escherichia coli 大肠杆菌质子逆向运输蛋白活性的测定 作者:Scarlett R. Holdsworth and Christopher J. Law日期:11/05/2014,浏览量:7699,Q&A: 0
Secondary active transport of substrates across the inner membrane is vital to the bacterial cell. Of the secondary active transporter families, the ubiquitous major facilitator superfamily (MFS) is the largest and most functionally diverse (Reddy et al., 2012). Recently, it was reported that the MFS multidrug efflux protein MdtM from ...

Measurement of the Electrogenicity of Bile Salt/H+ Antiport in Escherichia coli 大肠杆菌中胆汁盐/H+反向协同运输蛋白的电性活力测定 作者:Scarlett R. Holdsworth and Christopher J. Law日期:11/05/2014,浏览量:6350,Q&A: 0
The transmembrane proton gradient (ΔpH) is the primary source of energy exploited by secondary active substrate/H+ antiporters to drive the electroneutral transport of substrates across the Escherichia coli (E. coli) inner membrane. Such electroneutral transport results in no net movement of charges across the ...

Purification and Detection of a PDGA Depolymerase from Pusillimonas noertemannii 纯化和检测诺尔曼氏极小单孢菌中的PDGA解聚酶 作者:David Negus and Peter W. Taylor日期:11/05/2014,浏览量:7741,Q&A: 0
The purification of a target protein from a complex mixture of proteins is a challenging undertaking. If the target protein has been previously characterised, then information such as subcellular location, function, molecular weight and pI can be used for the design of a purification strategy. However, if the target protein is uncharacterised or ...

Accelerated Storage Stability Testing of a Potential Anti-Anthrax Therapeutic, EnvD 具有抗炭疽杆菌潜力的EnvD储藏稳定性提高的检测 作者:David Negus and Peter W. Taylor日期:11/05/2014,浏览量:7277,Q&A: 0
The purpose of stability testing is to determine how the properties of a particular therapeutic vary with time under the influence of specific environmental factors. Information regarding the long-term stability of therapeutics can be extrapolated by performing an accelerated storage stability study. Here, we describe an accelerated storage ...

Stable Transformation of Cyanobacterium Synechocystis sp. 集胞藻细胞的稳定转化 作者:Reinhard K Proels日期:11/05/2014,浏览量:11897,Q&A: 0
Cyanobacteria are prokaryotes, which perform oxygenic photosynthesis. Among them, the unicellular cyanobacterium Synechocystis sp. PCC 6803 (hereafter Synechocystis) is a well characterized model system for studies on oxygenic photosynthesis, light signal transduction etc. Moreover, Synechocystis is applied in ...

Fractionation by Ultracentrifugation of Gram Negative Cytoplasmic and Membrane Proteins 超速离心法分级分离革兰氏阴性菌细胞质和细胞膜蛋白 作者:Sara M Sandrini, Richard Haigh and Primrose P. E. Freestone日期:11/05/2014,浏览量:17605,Q&A: 1
Protein fractionation is a useful separation process which divides membrane proteins (including those located in the outer and inner membrane) and cytoplasmic proteins into discrete fractions. Fractionation of proteins can simplify analysis of the numbers of proteins present, and therefore make easier to characterize any environmentally or ...

An Experimental Model of Neonatal Nociceptive Stimulation in Rats 新生大鼠伤害性刺激的实验模型 作者:Jackeline Moraes Malheiros, Cristiane Amaral, Ana Teresa S Leslie, Ruth Guinsburg and Luciene Covolan日期:11/05/2014,浏览量:8398,Q&A: 0
In order to survive, preterm and/or sick neonates need diagnostic and therapeutic measures that may cause discomfort, stress and pain during a critical period of intense growing and modeling of the central nervous system (Anand et al., 2013). Scientific interest in the long lasting effects of the Neonatal Intensive Care (NIC) experience, ...

Pain Assessment Using the Rat and Mouse Formalin Tests 采用大鼠和小鼠福尔马林试验进行疼痛评估 作者:Nian Gong, Qian Huang, Yuan Chen, Meng Xu, Shuai Ma and Yong-Xiang Wang日期:11/05/2014,浏览量:23724,Q&A: 0
The formalin test was originally developed by Dubuisson and Dennis (1977), and has since been extensively used to assess pain-related responses. Rats and mice are the most frequently used animal models, though other species including cats, rabbits, guinea pigs, Octodon degus, domestic fowls, crocodiles, tortoises, toads and primates have ...

Measurement of the Number of Peroxisomes 过氧化物酶体数量的测量 作者:Michitaro Shibata, Kazusato Oikawa, Shoji Mano and Mikio Nishimura日期:11/05/2014,浏览量:8622,Q&A: 0
This is the detailed protocol for the measurement of the number of peroxisomes described by Shibata et al. (2013). It is difficult to count the number of organelles in a cell because of the thickness of plant leaves. To overcome this challenge, protoplasts were isolated from leaves, and the number of peroxisomes per protoplast was ...
