Are Eppendorf products free of RNA?

All products 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.

What is the meaning of the PCR Clean seal?

For molecular-biological requirements Eppendorf offers a new standard for uniform purity specifications. All consumables marked with the "Certified PCR Clean” label are guaranteed free of human DNA, DNase, RNase and PCR inhibitors.

Why are there double labels on the folding boxes, as "PCR clean" + "Sterile" or "PCR clean" + "Protein-free"?

Due to the modularization of purity grades, some products are labeled with more than one purity grade symbol. For example, the epDualfilter T.I.P.S. has the double seal "PCR clean "+ "Sterile" and the UVette the double seal "PCR clean" + "Protein-free" on the packing. The certification remains unaffected by the modularization.

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 .

Can products of the previous and new modular purity grades (with new seals) be used simultaneously in one application?

Yes, if no batch attachment is required for the application, products of the old and new modular purity grades can be used, as their specifications are the same.

Do the Eppendorf LoBind Tubes have the same material durability as all other micro test tubes from Eppendorf?

The Eppendorf LoBind Tubes completely satisfy the specifications of the Eppendorf Standard Safe Lock tubes with reference to centrifugation stability (exception: Protein LoBind Tube), lid tightness, pop up safety and chemical resistance. (See Application No. 56: The best material for original Eppis.)

Are the Eppendorf LoBind Tubes coated?

Not the Eppendorf LoBind Tubes are neither siliconized nor coated. The low binding affinity results from of a special type of polypropylene and the optimized manucturing process.

Can I use the Protein LoBind Tubes regardless of whether I am working with basic or acidic proteins?

The Protein LoBind tubes show protein low binding properties for both low and high pH values.

What is the material of the Eppendorf Protein LoBind Tubes and its influence on autoclavability?

The Protein LoBind material is a proprietary polypropylene (PP) blend with lower hydrophobicity allowing strong reduction of molecule binding to the PP surface. It has essentially same physical properties as the standard PP. Regarding autoclaving, please note the following: Our Protein LoBind Tubes 0.5 mL/1.5 mL/ 2.0 mL and 5.0 mL with snap cap withstand autoclaving when opened at 121 °C, 1 bar, 20 minutes. If the use of sterile tubes is needed, we rather recommend checking whether our Safe-Lock Tubes 0.5 mL/1.5 mL/ 2.0 mL and the 5.0 mL tube with snap cap (all without LoBind surface) made in Biopur quality may be more suitable here. The Protein LoBind Tubes 5.0 mL with screw cap, 15 mL/ 25 mL and 50 mL are not autoclavable. Please check whether the standard variants (without LoBind surface) offered in Sterile purity grade may be more suitable here.

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

Eppendorf tubes and plates including LoBind variants are resistant against 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.

Features

Prevent sample loss due to sample-surface binding with the Eppendorf Protein LoBind Tubes. With a unique, two-component polymer mix that helps to create a hydrophilic surface, protein recovery rate and downstream analysis is significantly improved.
With standard vessels, over 90 % of the sample can be lost within 24 hours due to binding to the plastic surface. Use Eppendorf LoBind Tubes and you don't need to worry about losing your precious samples any longer!

Eppendorf Protein LoBind^® products

Protein LoBind^® products are available in various formats, including tubes, microplates and deepwell plates to ensure the needs of your specific application are met. Whether you’re looking to scale down sample volumes or increase throughput, the LoBind range is here to help.

Superior protein recovery

Recover more than 90 % of your protein compared to standard vessels! Eppendorf Protein LoBind^® Tubes also offer a significantly higher rate of recovery after incubation for 96 hours in comparison to competitor low binding tubes. See Application note 180 for more details.

Outstanding signal during MALDI-TOF with Protein LoBind^® Tubes

Protein LoBind^® Tubes help to increase signal intensity during MALDI-TOF analysis, allowing you to detect and analyse at concentrations normally considered undetectable (1 pmol) when compared to standard tubes. In these graphs, the arrows identify the signals in each experiment. (Source: Dr. S. Seeber and Dr. Humeny, Institute of Biochemistry, University of Erlangen-Nürnberg, Germany, see Application Note 180 for more details).
