Are Eppendorf consumables free of RNA?

All consumables certified with "PCR clean" are tested free of human DNA, DNase, RNase and PCR inhibitors. The following applies from our point of view: where no human DNA is detected, there can also be no RNA, which is considerably more unstable.

Are lot specific certificates for the purity grades available in the internet?

Yes, the lot specific purity certificates, so-called Test report, can be downloaded at the certificates homepage .

Are Eppendorf tubes, plates (also LoBind variants), and pipette tips resistant to 100% acetonitrile?

Eppendorf tubes, plates including LoBind, and pipette tips are resistant to 100% acetonitrile only in room temperature conditions. Above 40°C and prolonged exposure (days) may lead to partial damage and is not recommended. For lower acetonitrile concentrations the resistance parameters will be better so prolonged exposure and higher temperatures may be possible. This must be however tested by the customer.

用途

特征

使用Eppendorf Protein LoBind Plates尽可能提高蛋白质样品回收率！ Eppendorf LoBind平板采用特殊的双组分聚合物混合物设计，形成亲水表面以确保更佳样品回收率。这些平板专为蛋白质研究或敏感的蛋白质组学测试方法而开发，通过减少样品与板表面的结合来提供卓越的结果。

高质量Eppendorf Protein LoBind

产品

产品包括吸附管、微孔板和深孔板在内的一系列形式，可满足各种样品量和处理量的不同应用需求。

卓越的蛋白质回收率

培养96小时后，Eppendorf Protein LoBind^® Tubes的蛋白质回收率明显高于其他低吸附型离心管。（详情请参阅Application Note 180 “Eppendorf LoBind: Evaluation of Protein Recovery in Eppendorf Protein LoBind Tubes and Plates”）。此款离心管尤其适用于蛋白质组学研究。在与德国汉堡大学附属医院开展的联合研究中，我们发现Eppendorf Protein LoBind低吸附离心管对蛋白质的吸附量远低于传统玻璃耗材。详情请参阅White Paper 136: “Glass Abdicates the Throne...and LoBind Becomes the New King of Proteomics”。

使用Protein LoBind^® Tubes在MALDI-TOF分析中获得优异信号

Protein LoBind^® Tubes有助于在 MALDI-TOF 分析过程中增加信号强度，与标准离心管相比，您可以在通常被认为无法检测的浓度 (1 pmol) 下进行检测和分析。在这些图中，箭头标识每个实验中的信号。（来源： Dr. S Seeber 和 Dr. Humeny，德国埃尔兰根-纽伦堡大学生物化学研究所（详情请参阅应用文献第180号）。
