The First Multi-Angle Light Scattering Detector for UHPLC!
The µDAWN™ Multi-Angle static Light Scattering (MALS) detector performs absolute characterization of macromolecules eluting from UHPLC, determining molar mass and size independently of retention time and molecular reference standards. This instrument offers superb sensitivity over a wide range of molar mass, size and concentrations. In most respects the µDAWN is similar to the well-established miniDAWN™ TREOS™, a workhorse MALS instrument used in hundreds of labs around the world for characterizing proteins and other molecules smaller than 50 nm in radius.
Distinctly from the miniDAWN, the µDAWN is uniquely suitable for use in conjunction with UHPLC Size Exclusion Chromatography (µSEC-MALS) thanks to its small interdetector dispersion. In some cases it may be used with ion-exchange or other types of chromatography. Regardless of the specifics, the µDAWN produces minimal band broadening in order to maintain the narrow peaks typical of UHPLC.
The µDAWN may also be used in microbatch (off-line) mode or in conjunction with a Calypso IICG-MALS system for characterization of macromolecular interactions: affinity and absolute stoichiometry, label-free and immobilization-free, as well as second virial coefficients, cross virial coefficients, average molar masses and sizes.

the Wyss Institute for Biologically Inspired Engineering at Harvard University and Sony DADC announced a collaboration that will harness Sony DADC’s global manufacturing expertise to further advance the Institute’s Organs-on-Chips technologies.
Human Organs-on-Chips are composed of a clear, flexible polymer about the size of a computer memory stick, and contain hollow microfluidic channels lined by living human cells – allowing researchers to recapitulate the physiological and mechanical functions of the organs, and to observe what happens in real time. The goal is to provide more predictive and useful measures of the efficacy and safety of new drugs in humans – and at a fraction of the time and costs associated with traditional animal testing.
“We are excited to apply Sony DADC’s deep manufacturing expertise to confront one of the major challenges in the life sciences by helping to accelerate the translation of the Wyss Institute’s Organ-on-Chips from the benchtop to the marketplace,” said Christoph Mauracher, Senior Vice President of the BioSciences division of Sony DADC. “The Organs-on-Chips have the potential to revolutionize testing of drugs, chemicals, toxins and cosmetics.”
This collaboration builds on the momentum the Wyss Institute team has gained recently on its Organs-on-Chips research program. With support from Defense Advanced Research Projects Agency (DARPA)*, National Institutes of Health (NIH), Food and Drug Administration (FDA), and pharmaceutical partners, more than ten Organs-on-Chips are currently under development at the Wyss Institute, including a lung, heart, liver, kidney, bone marrow, and gut-on-a-chip; there is also a major effort to integrate these organ chips into “human body on-chips” that mimic whole body physiology.
In February, Wyss Founding Director Don Ingber, M.D., Ph.D., who leads the Organs-on-Chips research program, received the prestigious 3Rs Prize from the UK’s National Centre for the Replacement, Refinement and Reduction of Animals in Research for the lung-on-a-chip. This month, the Society of Toxicology awarded him the Leading Edge in Basic Science Award for his “seminal scientific contributions and advances to understanding fundamental mechanisms of toxicity.”
“Our work with Sony DADC is a wonderful example of the Wyss Institute model in action,” said Ingber. “We collaborate with industry to help de-risk the technologies we develop, both technically and commercially, and therefore expedite their translation into real world applications.”

A novel ophthalmic solution from R-Tech Ueno (Tokyo, Japan) made using Novozymes Biopharma’s recombinant human albumin has recently obtained FDA approval to undergo Phase I/II clinical trials in the United States.
Novozymes Biopharma, part of Novozymes A/S world leader in bioinnovation, today announced that an ophthalmic solution made using its recombinant human albumin, has been approved for Phase I/II development by the FDA.
Designed by R-Tech Ueno, RU-101 ophthalmic solution is being trialled as a therapy for severe dry eye, for which no effective treatment is currently available. The recombinant human albumin is part of Novozymes Biopharma’s albumin range. Novozymes Biopharma has a strong reputation in the industry for helping customers in the safe and successful commercialization and approval of new products.
The prevalence of severe dry eye, where patients suffer from instability of the tear film, continues to increase. It is the most diagnosed of all ophthalmic disorders and estimates put the market at approximately 1.5 billion USD. The trials for RU-101 ophthalmic solution will move ahead in two stages, the first of which will assess safety using a placebo control, and allow confirmation of the maximum dose. The second stage will then use this maximum dose for 12 weeks to evaluate the safety and effectiveness of RU-101 ophthalmic solution.
Dermot Pearson, Marketing Director at Novozymes Biopharma said, “Novozymes is dedicated to supporting our customers in the drug development and testing stages, and in assisting with the optimisation of their pathways through regulatory approval procedures. We are therefore delighted that RU-101 ophthalmic solution has been approved for clinical testing.”
Novozymes Biopharma’s recombinant albumin is designed to provide quality performance benefits when included in drugs developed by our customers. It was selected as a key component of this novel therapy back in 2011, due to its proven high quality and enhanced safety profile. Animal-free, with an exceptional purity profile and convenient liquid format at room temperature, recombinant albumin delivers consistent levels of quality, leading to reduced lot testing and vendor auditing.
All Novozymes’ recombinant human albumins deliver stable, safe and regulatory compliant ingredients for drug delivery and formulation, and are compliant with the National Formulary (NF) rAlbumin human monograph published by the United States Pharmacopeia (USP).

Olympus will exhibit its BX3 upright microscope systems and VS120 virtual slide scanner at ECP 2013.
Designed specifically to meet the needs of a range of pathology applications, the systems ensure robust diagnosis and discovery alongside ergonomic operation.
Enhancing the workflow of research and diagnostic centres alike, the latest range of Olympus pathology microscope systems and accessories will be on show at the 25th European Congress of Pathology (ECP) 2013, 31 August – 4 September in Lisbon, Portugal. Delegates can visit booth 14 to view the Olympus BX3 range of upright microscopes and the Olympus VS120 virtual slide scanner.
The BX3 range of upright microscope offers complete flexibility in pathology applications due to a modular design. Ergonomics is a priority, and each user can set up the microscope to match their posture, for both comfort and convenience. The range includes several models focused on either clinical or research microscopy, and delegates of ECP will have a chance to view the fully automated BX63, the research-focused BX53 and the BX43 clinical imaging system.
The BX63 delivers high performance automated microscopy for research applications, and the system on display at booth 14 will also feature the unique dual chip Olympus DP80 digital camera. Combining colour and monochrome chips within the same housing allows joint colour and fluorescent imaging in pathology applications, for example when combining histological staining with fluorescent dyes on the same sample. The BX3 range lends itself to easy integration into existing workflows, and visitors can also discover how the BX43 clinical microscope is compatible with both third party cameras and software.
With a modular design, the research-focused BX53 can be easily customised and the system on display at ECP will feature the Olympus discussion tube unit. Allowing multiple users to observe the same specimen using separate eyepieces, this system is ideal for both teaching and consulting, as all users see the actual image, not a digital representation. The unit is a powerful tool for reviewing difficult cases with other pathologists and colleagues to discuss diagnoses, and delegates of ECP are invited to bring along their own samples to examine with colleagues.
Also on display will be the Olympus VS120 virtual slide scanner, which features the flexibility, resolution and image quality necessary for meeting the demands of pathology research workflows. The system creates a “virtual slide” high-resolution image of the complete specimen at a range of magnifications, which can be electronically stored on a central server. This enables instant access and simultaneous viewing anywhere in the world, omitting the need to transport specimens between laboratories, reducing slide archives and securing a permanent digital record of the sample.
Delegates will discover how the latest in Olympus imaging technology enables new possibilities for clinical and research pathology applications alike.
