  • "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, SciLifeLab and KTH - Royal Institute of Technology
  • "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, previous 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. Arrayjet, led by their CEO Iain McWilliam, has proven to be knowledgeable and a pleasure to work with and I look forward to collaborating with their team in future developments.”

    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.

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.”

    An Shuang, Array Production Supervisor, CapitalBio, 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, Principle Investgator, 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."

    Ignacio Pino, President, CDI Laboratories
  • "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 Marathon Argus 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.''

    William Willats, Professor of Molecular Agri-Diagnostics, Newcastle University

  • “Transfer to Arrayjet technology has had huge benefits for our cancer research and biomarker discovery. Our team can now produce 100 slides in a working day, using just 1 µg of cDNA per gene of interest. The automated process enables us to focus fully on our research knowing arrays will be printed reliably and reproducibly every time.”


    Manuel Fuentes, Cancer Research Center
  • Arrayjet came highly recommended by Dr. Heng Zhu, a pioneer and co-inventor of protein microarray technology at Johns Hopkins University.  We already had a contact printer in the lab, but after seeing the Ultra Marathon in action I dreamed of acquiring one of Arrayjet’s non-contact printers for a long time. 

    More recently, we’ve been able to print extra slides for other researchers working on SARS-CoV-2 projects.  The sheer speed of Arrayjet’s “on-the-fly” printers makes this possible.  The intuitive software is continually updated, and the technology itself is very modern so I trust it in terms of reliable performance and quality printing.  The spot morphology is also very good; the microarrayer from Arrayjet is one of the best that I’ve ever seen."
