"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."

“I’m one of the six co-founders of CDI Laboratories and act as a consultant on the scientific advisory board. Over the past few years, we had been using contact printing technology, which was causing several quality issues and we needed to seek an alternative, improved solution to our fast-growing and developing business model. After extensive research, testing and development of our ‘HuProt’ Human Proteome Array onto Arrayjet’s printing platform by accessing their in-house printing service (Arrayjet Advance), the board of CDI decided to technology transfer by purchasing an ‘Ultra Marathon II’ for development & manufacturing. 

Arrayjet Advance allowed us to determine the number of protein samples (circa 20,000 printed in duplicate) to be delivered to the slides that were highly consistent with piezo actuation, non-contact inkjet printing. 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.”

"Our Arrayjet Marathon has been instrumental in achieving the throughput and reliability that have been needed for the production of antigen arrays for validation of 47,000 antibodies within the Human Protein Atlas. It has also shown to be highly suitable for the 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."

“CDI Laboratories recently purchased an Arrayjet ‘Ultra Marathon II’ to print microarrays for our ‘HuProt’ product line, focussed arrays with a 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. These studies provided me with the evidence there would be vast leaps in repeatability and ultimately higher-quality arrays than I could ever imagine. Furthermore, with enhancements in product quality, it will enable CDI to grow the business in increased sales with more confidence than ever before and will make our expansions plans in other microarray experiments more achievable. All my interactions with Arrayjet over the past two years has reassured me that collaboration was a natural way forward, as we have common goals and similar expansion strategies. Arrayjet is a professional outfit, with great customer service, and supported us with our technology transfer every step of the way. Microarray printing is at the heart of everything CDI laboratories do and it is great to partner with a company that lives and breathes the same principles.”

"Access to the Ultra-Marathon through Arrayjet Advance Services has allowed us to explore product options that would otherwise be out of reach”.
Paul Ko Ferrigno, formerly of Avacta Life Sciences Ltd


“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, Wellcome Trust Sanger Institute


“We have been using Arrayjet Advance for two years now and the service has been outstanding! Their technical expertise is second to none and outsourcing the development and printing of our protein arrays has shortened our time to launch. They have truly been a partner to IDS in our microarray development and it’s why we have selected them to scale up our array manufacture ahead our commercial launch.”

Stuart Granger, CEO, Identity Sciences, LLC


"[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, USAMRIID


"We have been very happy with the performance of our new Marathon microarrayer. We were surprised and pleased at how easy it was to print high-quality arrays with only minimal optimization" 

Dr Dave Lin, Cornell University 


"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 


"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, Newcastle University 

“We chose to work with Arrayjet because their instruments are unique in how many samples they can print.  By outsourcing to Arrayjet Advance, we have had access to a team of knowledgeable microarray scientists who optimised every part of our protocol, and we learned much from them. 

Partnering with Arrayjet has given us the capability to print our 16k human protein arrays in lots of 1000.  Batch variation is minimal and the alignment and morphology of the spots are excellent, and I have no hesitation in recommending their technology.”

Andreas Weinhausel, Austrian Institute of Technology

“Our department has been working with Arrayjet for over a decade.  Utilising the knowledge our researchers have developed a method for printing polysaccharides. The speed, precision and consistency of their printers has provided robust data for the study of polysaccharide interactions in plant cell walls.  The ongoing support from the Arrayjet team helped us secure funding from The Carlsberg Foundation to upgrade our R&D printer to a modern and intuitive Marathon Argus.  We can now work with triple the number of samples and have increased our high throughput capabilities, ensuring the future of the department with the latest technology.”

Bodil Jørgensen, Copenhagen 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.”
