产品简介:

Nanodisc可使膜蛋白处于一个类似磷脂双分子层的环境中,从而保证膜蛋白能够像在天然的细胞膜中维持其构象和生物学功能。Nanodisc这种全新的膜蛋白提取工具打破了原有提取方法的瓶颈,能够很好地维持膜蛋白的稳定,如此可以推动膜蛋白领域的研究工作。Nanodisc是由膜支架蛋白(membrane scaffold proteins,MSPs)和磷脂分子构成的磷脂双分子层类膜结构。整合到Naonodisc中的膜蛋白可以保持其生物学活性,为膜蛋白的研究提供了便利。

根据不同的实验情况,科研人员可以使用两种不同的策略来包裹其想要获得的膜蛋白。对于已经分离并溶解在去污剂中的膜蛋白,我们推荐使用膜支架蛋白(MSPS)并配合磷脂分子使用。针对不同的需求我们提供多种膜支架蛋白和多种磷脂分子以及不同配合的试剂盒供选择。而用于无细胞表达系统所生产的膜蛋白,我们推荐使用已经组装好的空载纳米磷脂盘来包裹/插入其目标膜蛋白。您可以直接购买组装好的纳米磷脂盘或相应的试剂盒自行组装。

产品优势:

1)德国制造, 欧美领先蛋白纯化产品供应商;

2)专用于膜蛋白的研究,提供带有His-tag和不带标签的MSPs膜支架蛋白(人源和鼠源);

3)提供四种不同尺寸的MSPs膜支架蛋白 (MSP1D1/MSP1D1-dH5/MSP1E3D1/MSP2N2);

4)分别提供配备DMPC、POPC和DMPG磷脂的试剂盒(根据研究发现,不同膜蛋白在不同磷脂双分子环境下其活性有所不同,例如:真核磷脂环境和原核磷脂等环境,可按照实际需求订购,见图1);

5)详尽的操作指南和专业技术支持;

6)配合PureCube Rho1D4 Agarose使用,是有效的膜蛋白提取解决方案;

7)Nanodisc系列产品MSP1D1-His和MSP1D1dH5-His的应用已刊登在《美国化学会-应用材料与界面》(ACS Applied Materials & Interfaces): Zeno, W.F. et al. Spectroscopic Characterization of Structural Changes in Membrane Scaffold Proteins Entrapped wit hin Mesoporous Silica Gel Monoliths. Applied Materials & Interfaces 2015, 7, 8640-8649.
