CEO WELCOME

Welcome Dear Reader, In 2015, we conducted a global survey of over 1,000 scientists to find out how Tecan adds value to their work. The resounding answer from the respondents was the solid reliability that Tecan stands for. Every day around the world, Tecan products are used in key studies in life science labs, as well as in diagnostic labs for daily operations that are critical to human lives. Tecan provides a high level of reliability and responsiveness that many people have come to depend upon. For Tecan Partnering, scientists and engineers told us how they envision Tecan empowering their life sciences and diagnostic applications. And by working together with Tecan, they can launch new, innovative solutions faster to market and better than they could on their own. As a consequence, we clearly formulated what we stand for and refreshed our brand. We started by defining our new vision: Every Lab. Every Day. Empowered. The vision is not about us. It’s about empowering you, our customers and partners, wherever you are around the world, to achieve greater things than you could do before. Next, we looked at what we need to commit to, in order to achieve our vision. Our promise to you is to be Always There For You. We strive to be closer to customers and partners, to be more responsive, and help you achieve your goals by contributing our expertise wherever we can. This issue of the Tecan Journal – in your hands or on your device – takes a closer look at some exciting stories of empowerment of our customers. New to the Tecan Journal are in-depth stories on the trends that shape our industry, both today and in the past. We take a look at what might happen as next generation sequencing moves closer to the clinical lab, and at the fascinating story by Siddhartha Mukherjee of how cancer research funding took off through the efforts of a handful of committed individuals and the unlikeliest of circumstances. We also present product news about the Fluent™ laboratory automation solution and Spark™ reader that empower your work in drug discovery and cell-based assays respectively. In October 2015, we were very excited to announce the acquisition of Sias by Tecan. With Sias joining our family, this heralds the growth of Tecan Partnering, with a wider set of solutions for modular and complete systems. Sias customers will immediately benefit from Tecan’s global sales and support organization. Please do send us your thoughts and opinions at hello@tecan.com. We’re always there for you.

whether sequencing the DNA from a tumor biopsy is sufficient for diagnostic and therapeutic purposes, or if sequence data generated from a healthy sample from the same patient should serve as a matched control for comparison purposes. As noted in the article Cancer Sequencing Controls, sequencing a patient’s normal DNA is not common practice in clinical labs and would certainly add to the cost compared to analyzing only tumor DNA.2 However, the extra workload and cost must be weighed against the risk of basing treatment decisions on inaccurate information and an incomplete diagnosis. The results of an analysis of 815 paired tumor-normal samples from patients with 15 different tumor types illustrated the potential to misinterpret somatic alterations identified in the tumor genome using NGS as tumor-specific mutations.3 Many of the same changes were shown to be present as germline variations in NGS analysis of the normal

The envisioned transition in healthcare to a more efficient and cost-effective strategy based on personalized medicine will require access to an abundance of genetic information for each and every patient, at various stages of health and disease. Thus, rapid, high throughput, massively parallel sequencing performed in a regulated environment will be the new norm for clinical labs. Clinical NGS

The other two thirds were germline alterations, and would have led to false positive findings – including in cancerpredisposing (potentially actionable) genes – if only the tumor DNA had been sequenced, and that information alone used to inform therapeutic decisions.

ONCOLOGY

A very short history of cancer research funding In his book The Emperor of All Maladies, Siddhartha Mukherjee tells the story of one of the turning points in the history of cancer medicine. A turning point that he dates to May 1947. At this time, cancer was a fatal disease and as a subject of discussion it was rarely mentioned among close friends, least of all at polite social gatherings. Cancer was an ugly disease that appeared to harvest lives regardless of the individualâ&#x20AC;&#x2122;s background, lifestyle or social stature. Its victims were carved up in radical surgical procedures or subjected to experimental chemical trials with little or no understanding of the underlying mechanisms. After a brief period of remission, most patients succumbed to new tumors, some far more aggressive than their predecessors. Research was performed by a handful of dedicated doctors who were nameless, faceless and relegated to the basements of hospitals to perform research with dubious outcomes. If cancer was ever to have a future as a disease to be tackled seriously, it needed serious funding. Cancer had to become a disease that people were not afraid to talk about in public. And the focus had to be on a patient that nobody could deny deserved all the help in the world.

The story begins 19 years earlier, with a baby in a basketâ&#x20AC;Ś

TECAN JOURNAL 1/2016

ONCOLOGY

The baby girl was abandoned on a seat in the Sheridan Square Film Theater in Pittsburgh at the start of the Great Depression of 1928. The note attached to the baby read:

Please take care of my baby. Her name is Catherine. I can no longer take care of her. I have eight others. My husband is out of work. She was born on Thanksgiving Day. I have always heard of the goodness of show business and I pray to God that you will look after her. Signed, a heartbroken mother. The baby was named Catherine Variety Sheridan, her surname after the theater where she was found, and her middle name after the Variety Club, an association of actors, producers, directors, writers and film theater owners that adopted Catherine as their ward. The media exposure from the adoption of baby Catherine was far greater than the members of the Variety Club could ever have dreamed. During the war years, the entertainment industry had boomed and Hollywood realized that they had earned the adoring, if somewhat fickle, goodwill of the general public. The Variety Club redefined itself as a philanthropic organization that was keen to reinforce the idea of ‘the goodness of show business’.

Every dime counts The Variety Club was inspired by the March of Dimes, a campaign initiated by the actor Eddie Cantor when Franklin D Roosevelt was re-elected President. In 1936, Roosevelt, himself a polio victim, established the National Foundation of Infantile Paralysis. Polio research and patient care received a massive boost in funding thanks to the nationwide campaigning efforts of the March of Dimes, which reached out through the radio waves into the living rooms of private homes across America. Dimes in envelopes flooded into the White House from factory workers, housewives, schoolchildren and Girl Scouts. In the first year alone, 2,680,000 dimes were collected. By the late 1940s, John Enders had succeeded in cultivating the first live poliovirus in the lab. The development of the polio vaccine was a direct result of the public funding initiative. In 1938, FDR focused on cancer, and signed legislation

Empowered by a rare positive result, Farber was now obsessed by his vision of a hospital dedicated to the research of childhood leukemia. Koster had found his man. Together, Koster and Farber began to hatch plans to make the hospital a reality. In 1948, they launched the Children’s Cancer Research Fund. Their first raffle raised an impressive $45,456, but hardly enough to open a hospital. Koster recalled the success of the Catherine Sheridan campaign and convinced Farber that they needed a poster child, a mascot for childhood leukemia.

Going to the country Farber learned that the fight against cancer was not just about science – it was as much about being seen and heard. He needed to understand the intricacies of political lobbying. He needed a clear strategy and a reason for people to believe in his cause. Gaining and sustaining the public’s attention required the persuasive art of advertising. Enter Mary and Albert Lasker. Mary Lasker was a star saleswoman, a long-time lobbyist and a political campaigner. A survivor of pneumonia and the Spanish flu of 1918, she became the most influential health activist of her day.

Farber had the scientific credentials needed to sway Congress, and the Laskers stood for constant lobbying ‘on the Hill’ and extremely effective advertising. Most significantly, Mary Lasker’s work ultimately led to President Nixon famously declaring War on Cancer with the signing of the National Cancer Act of 1971.

Where we could previously generate 16 compound plates at a time, we can now produce 32 in parallel, and in a short time frame. And it’s even better for dilutions; where we could previously create about 20 single dilutions in parallel, we can now do 56 in duplicate. It’s basically tripled the speed of most of our protocols. We are also considering installing a bulk dispense module for DMSO below the workdeck to further increase throughput, as the system’s Robotic Gripper Arm can easily access this below-deck area without too much compromise in the instrument’s overall capacity.” “Although our workstation is very simple in automation terms, the Fluent platform’s high definition liquid handling capabilities are still very impressive. The Multiple Channel Arm moves very quickly compared to most pipetting robots on the market, and the Path Finder™ feature means that it always takes the optimal route between plates. The Active Stop and Resume function – introduced with the latest software update – is also fantastic; if you see something wrong with the set-up on the workdeck, you can just open the door and it stops. Once you’ve dealt with the problem, you just press ‘Retry’ and it picks up where it left off, avoiding the need for laborious resetting or reprogramming of the instrument. The software is also both powerful and very convenient to use; the Zero G teaching capability makes it extremely quick and easy to define plate positions, and almost every aspect of

When Tecan advised us that the updated system capable of dispensing aqueous solutions was being launched, we immediately looked into this. As soon as we began testing the D300e in house, it was clear that this instrument was ideal for our needs, eliminating the cost and wastage associated with predilutions.” Using the D300e has significantly reduced the amount of material required for each experiment, as well as minimizing the cost of consumables, and has proved very popular within the lab.

This is very important in such a busy lab, allowing numerous projects to use the device virtually in parallel,” Stephanie concluded.
