  • "Our Arrayjet Marathon has been instrumental in achieving the throughput and reliability that have been needed for production of antigen arrays for validation of 47,000 antibodies within the Human Protein Atlas. It has also shown to be highly suitable for production of our large scale arrays that comprise over 20,000 features per array in both antigen and reverse phase serum arrays. We have arrayed more than 12,000 slides with the Arrayjet Marathon over the last five years and it has become a very important part of our research group and the SciLifeLab National Affinity Proteomics protein array facility."

    Peter Nilsson, Principal Investigator, The Human Protein Atlas, Stockholm
  • "We are very pleased to be working with Arrayjet, as we see high throughput inkjet technology as very much the future of protein microarraying. The Super-Marathon enables us to do things that are simply not possible with a pin spotter, and we've given it pride of place in our new, highly automated facility."

    Alan Sawyer, Director at EMBL Monoclonal Core Facility
  • "Arrayjet’s JetSpyder sample aspiration device effectively eliminates any cross contamination between protein samples, so the quality of our slides is significantly improved. Previously we could produce just over 150 slides of acceptable quality in a print run, too slow a pace for the scale and growth of current and future demands; being able to print up to 1000 slides quickly, in a highly efficient manner was incredibly appealing to us."

    Heng Zhu, Professor at Johns Hopkins School of Medicine, Baltimore
  • "[The] Arrayjet's efficiency allows for fast array spotting that is also very reproducible. The high-capacity platform is helpful in producing multiple array slides per printing run. The software is user-friendly and the tech support has been nothing short of outstanding with any situations we have encountered."

    Dr Robert Ullrich, Principal Investigator, USAMRIID, Frederick
  • “Since becoming a user of a Marathon Inkjet Microarrayer, I have been extremely happy with the service and expertise provided by Arrayjet. Any questions about the technology are answered promptly by knowledgeable and friendly in-house scientists and support staff. The machine is easy to use and can print many samples quickly and accurately, which is perfect for any kind of high throughput methods development project!”

    Dr Laura Wood, Postdoctoral Researcher, Wellcome Trust Sanger Institute, Cambridge
  • “I am impressed by the advanced technology and the innovative design of the Arrayjet Ultra Marathon II Microarrayer. We are glad to be the first user of the Arrayjet Ultra Marathon II Microarrayer with the camera module. Arrayjet constantly upgrades its products. This makes us optimistic about the prospect of long-term partnership with Arrayjet.”

    Dr. An Shuang, Head of Array Production, CapitalBio Corporation, Beijing
  • "The combination of an excellent product in their microarray printers and a responsive technical support team to assist with bespoke solutions to individual project needs were two of the many attributes that attracted us to work with Arrayjet. At every step of the design of an in-house microarray chip, we had at our disposal a dedicated team of application specialists who were very cordial and available to respond to our many queries. It was on the back of this excellent support that we eventually purchased one of their microarray printers and we have continued to enjoy excellent technical training on the instrument and engineering support."

    Dr. James Tuju, Principal Investigator, KEMRI Wellcome Trust, Kenya
  • "CDI Laboratories recently purchased an Arrayjet ‘Ultra Marathon II’ to print microarrays for our ‘HuProt’ product line, focussed arrays with smaller subset of proteins for discovery arrays and hybridoma project work. CDI are planning to print monoclonal arrays and membrane protein arrays with the new technology in the near future. Arrayjet’s technology was chosen as we needed to quintuple capacity, preferably with one Instrument, its hi-tech, precise and user friendly capabilities was an obvious benefit. One of the added advantages of the company structure is that they provide in-house printing through ‘Arrayjet Advance’ and we were able to carry out several studies over several months to reaffirm our belief that the technology would improve many facets of our operation."

    Dr Ignatio Pino, CEO, CDI Laboratories, Baltimore
  • "The production of microarrays of complex and diverse carbohydrates presents particular unique challenges. The Arrayjet Sprint works very well for this purpose and in our experience is superior to pin based printers. We have found that the Sprint is very fast, accurate and most important, able to handle polysaccharides and oligosaccharides with widely different chemical and physical properties. What is also impressive is that we are able to print extracted material directly without clean up, despite the fact that some extraction solvents are very harsh, for example 4 M sodium hydroxide.''

    Prof William Willats, University of Copenhagen
  • "Access to the Ultra-Marathon through Arrayjet Advance Services has allowed to us to explore product options that would otherwise be out of reach”.

    Paul Ko Ferrigno, CSO, Avacta Life Sciences Ltd, York
  • "We are glad to have found a dedicated partner that accepted the specific
    challenges of our regulated production environment and developed an instrument tailored to our needs.”

    Dr. Dr Holger Wenschuh, CEO, JPT Peptide Technologies
  • "The Marathon instrument from Arrayjet was selected for the quality of the spotting, the small size of the spots (50-60 µm) on various substrates and because it is provided with a dust-free chamber that is temperature and humidity controlled. We also found it to be very competitive in cost."

    Prof. Erik Goormaghtigh, Head of Structure and Function of Biological Membrane, Université Libre De Bruxelles
  • "Arrayjet’s Marathon Argus was selected to support and integrate with our Zeptosens RPPA microarray platform and this has helped produce faster results for both in vivo and in vitro studies. We can increase the printing of high throughput of biomarkers whilst significantly optimising quality. We’re delighted with this ability to scale up our microarray printing.”

    Dr. Ashraf Elamin, Manager Proteomics, Phillip Morris International
  • "RHS is at the cutting edge of IVD technology and we are delighted to partner with Arrayjet. The Marathon Argus will provide the means to effect fast and accurate microarray production."

    Dr Michelle Fraser, CEO, Reproductive Health Science
  • "We are delighted to work with Arrayjet to build translational capacity in our state-of-the-art glyco-bioanalytical facility. The speed, spot quality and superb batch-to-batch reproducibility of the Marathon Argus provides us with the reassurance to manufacture quality commercial glycoarrays. Furthermore, Arrayjet was able to offer both dehumidification and humidification, so we never have a need for downtime, which is vitally important for the seamless continuity required within our operations."

    Dr. Chris Davis, General Manager, Institute for Glycomics, Griffith University
  • "We chose Arrayjet Super Marathon for production because we are impressed by its high throughput, superior stability and consistency of printing performance.This will minimize the reaction and produce easy-to-use screening tools."
