Automated TruSeq® Stranded Total RNA Library Preparation Method for Eppendorf epMotion
Hamburg, February, 2014
Today Eppendorf announces the release of the epMotion automation method for Illumina’s TruSeq Stranded Total RNA library preparation kit for next-generation sequencing as “Illumina Qualified.” “Illumina Qualified” indicates that Illumina’s analysis of libraries prepared with this epMotion method has shown the libraries to perform comparably to those prepared manually.
Sample preparation for next-generation sequencing (NGS) involves extensive manual processing that can affect reproducibility. Eppendorf epMotion Liquid Handling systems are important tools for labs that want to significantly increase throughput and consistency of results. The automation of labor-intensive steps in NGS sample prep, like pipetting, mixing, temperature control and magnetic separation, brings about a standardized and streamlined process, with significantly reduced hands-on time and minimization of human errors.
“Eppendorf’s method for TruSeq Stranded Total RNA provides our customers with another great option for high throughput automation,” said Peter Fromen, Senior Director of Product Marketing at Illumina. “Eppendorf is one of the leading providers of automation to NGS users, and we are looking forward to additional methods from them in the near future.”
“The Stranded Total RNA sequencing library preparation using the epMotion minimizes our hands-on time while achieving overall high reproducibility. This streamlines and standardizes our sequencing workflow, thereby allowing for higher sequencing throughput. We are looking forward to collaborating with Eppendorf on additional automated library prep protocols,” said Dr. Wei Chen, Head of the Scientific Genomics Platform at Max Delbrück Centre for Molecular Medicine in Berlin, Germany.
“This method is tailored for 8, 16 or 24 samples of 100 to 1000 ng total RNA and gives sequencing ready libraries in 9 to 12 hours. While this is not much faster than the manual process, the hands-on time is significantly reduced as the automated process needs less than one hour preparation time in total,” said Dr. Reza Hashemi, Executive Director of Portfolio Management Liquid Handling at Eppendorf.
Additional automated methods for NGS library preparation from Illumina are currently in development.

Protect your pipette after over pipetting with new Eppendorf ep Dualfilter T.I.P.S® SealMax filter tips
Hamburg, January 2014
New ep Dualfilter T.I.P.S® SealMax filter tips from Eppendorf are designed to protect samples and pipettes against contamination through aqueous sample liquid during accidental over pipetting, as well as against contamination through aerosols and biomolecules.
In laboratories where research with precious, potentially harmful, samples is conducted, filter tips are mostly used. Working with adjustable volume pipettes can put the user at risk when combining pipettes with filter tip sizes that are beyond their capacity. An over pipetting situation can cause pipette contamination due to the sample passing through the filter. With the new ep Dualfilter T.I.P.S. SealMax, researchers can be confident their pipette is safe.
These filter tips do not only build a reliable barrier against liquid, should accidental over pipetting occur during routine laboratory work. The violet and white filter layers also retain practically 100% of all aerosols and biomolecules. Unlike conventional self-sealing tips, ep Dualfilter T.I.P.S® SealMax filter tips combine two-phase filter protection with an innovative fluid and moisture barrier without the risk of the sample liquid being inhibited (e.g. PCR) after any contact with the filter. When in use, the tips initially seal as the aqueous liquid passes through the first hydrophobic filter layer, built to retain drops and splashes.
The sample then passes into a second filter layer, which creates a reliable barrier against the liquid and protects the pipette against contamination. Further information on specific sample recovery features, PCR inhibition and aerosol protection are available on your local Eppendorf website.
The PCR clean / Sterile (sterile and pyrogen-free) purity grade of Eppendorf’s ep Dualfilter T.I.P.S® SealMax filter tips makes them safe for use across a range of applications. Lot-specific purity certificates are available online.

Count on it - Eppendorf’s new Multipette M4 dispenses up to 100 times without refill and counts all executed dispensing steps
Hamburg, January 2014
Eppendorf’s new Multipette M4 is the latest addition to the company’s hand-held serial pipetting range, designed to minimise the time and effort required for precise and highly accurate repeat dispensing tasks.
The new Multipette M4 works with nine sizes of Eppendorf Combitips advanced. A built-in sensor detects the Combitips automatically, showing the tip volume on an easy to read display and eliminating the need for manual volume calculations. In addition, the new central Combitip ejector supports one-handed operation for contact-free tip ejection that avoids any risk of contamination.
Since there are 20 volume settings for each of the nine Combitips, the Multipette M4 can dispense volumes from 1 µL to 10 mL and completes as many as 100 operations without refill. This is significantly more than similar hand held dispensers on the market. An integral step counter displays the number of steps executed, allowing the user to resume with confidence should there be any interruption while dispensing.
With the ability to conduct a maximum of 100 dispensing actions accurately and precisely, the new Multipette M4 is ideal for applications involving 96-well plates, for example. Based on the positive displacement principle it also eases the handling of viscous or volatile liquids and lowers the risk of contaminating the Multipette itself when dealing with radioactive, toxic or other hazardous materials. Unlike air cushioned pipettes, the Multipette M4 allows accurate and precise dispensing of difficult to handle viscous solutions as well as liquids with high vapour pressure.
Repetitive dispensing procedures, such as those required in plate filling, aliquoting and kit usage, can be very time consuming, with ample opportunity for errors and inconsistencies. The new Multipette M4 provides a new, highly efficient solution for quick and safe dispensing that laboratories can rely on.

Research on Spatial Memory in Bats Wins 2013 Eppendorf & Science Prize
The Israeli scientist, Michael Yartsev Ph.D., CV Starr Postdoctoral Research Fellow of the Princeton Neuroscience Institute at Princeton University has won the 2013 Eppendorf & Science Prize for Neurobiology. Dr. Yartsev uses an unusual animal model, the bat, to study the underlying neural mechanisms of spatial memory and navigation in the mammalian brain. The use of the bat, along with the development of techniques to record the activity of single cells in brains of these flying mammals, allowed him to conduct a comparative examination of current hypotheses as well as to provide novel insights into the neural codes underlying the representation of three-dimensional space in the brain. His work also underscores the potential benefits of using new animal models in neuroscience.
Dr. Yartsev writes, “All animals on our planet, either on the ground, the ocean depths, or in the sky, must have knowledge of their whereabouts to survive. How the brain solves the problem of knowing where we are in space is a core question in neuroscience. During my doctoral research in the laboratory of Dr. Nachum Ulanovsky at the Weizmann Institute in Israel, I studied the neural activity of spatially selective neurons in the hippocampal formation of freely behaving and flying bats to gain insight into this problem. Using the bat’s unique behavioral repertoire and sensory systems, I now also plan to study the computations taking place in the brain during decision making processes.”
According to Prize Jury Chair and Science Senior Editor, Dr. Peter Stern, “The results obtained by Michael Yartsev’s work are novel and significant in our understanding of how three-dimensional space is represented in the mammalian hippocampus. They suggest that place cells cover volumetric space uniformly and isotropically. His results point towards the underlying mechanisms of how the brain achieves these astonishing feats.”
The annual US$25,000 Eppendorf & Science Prize for Neurobiology honors scientists, like Dr. Yartsev, for their outstanding contributions to neurobiology research. Dr. Yartsev is the twelfth recipient of this international award. He will be presented with the Prize at a ceremony held during the week of the 2013 Annual Meeting of the Society for Neuroscience in San Diego.
The next deadline for applications for the Eppendorf & Science Prize for Neurobiology is June 15, 2014. For more information about Dr. Yartsev and the Prize, visit www.eppendorf.com/prize.
