Securing supply of high-end reagents for SARS-CoV-2 PCR tests

Proudly empowering a global response to the COVID-19 pandemic

The end of the COVID-19 pandemic will rely on the tools of science – tools built on high-quality raw materials and reagents. Securing their availability has been our success story in this pandemic. And it’s a story of change, of tireless teamwork, and of strong collaborations.


The last two years have been particularly demanding for our teams. We joined forces with business partners and organizations to accelerate progress at a time when the stakes were highest. While millions heeded to calls from governments to shelter in place, Roche sites continued to operate around the clock.

Manufacturing teams kept production uninterrupted. Logistics experts shipped urgently needed reagents and assay components around the world. Managers, researchers, and sales representatives devised new communication channels to offer solutions and results as our customers contributed to the global pandemic response.

Our efforts paid off. 

We drastically increased output of key components used in SARS-CoV-2 PCR tests by:

The reward has been to see the outcome of our efforts. We proudly watched partners meet peak demand for fast and reliable molecular SARS-CoV-2 diagnostic assays running on CustomBiotech reagents. The trust vested in our high-quality, thermostable, lyo-ready materials – like NxtScript Reverse Transcriptase to detect RNA viruses at high temperatures – is testimony to the consistently high performance that diagnostics developers have come to expect of CustomBiotech. Our KAPA3G HotStart DNA Polymerase also became a key component of point-of-care SARS-CoV-2 PCR tests, delivering the quick and reliable results that are critical to healthcare management and patient life at times of crisis. 

Finally, molecular diagnostic assays shipped over long distances and requiring maximum flexibility in PCR workflows incorporated HawkZ05 Fast, our market-leading dual activity polymerase that is formulated glycerol-free at high concentrations and excels in the detection of low-copy targets. 

Lessons learned today inform preparedness for tomorrow


Product performance and reliability is one reason for the widespread use of our reagents. Peace of mind is the other. The diagnostics space is a rapidly evolving landscape, both in terms of the disease-causing targets that must be addressed and the competition to produce faster, more sensitive detection tools.

CustomBiotech understands those demands and the bottleneck that sourcing reagents can become in the context of unpredictable delivery.

Therefore, we emphasize security of supply for all molecular diagnostics reagents, whether amplification enzymes, dNTPs, nucleotide mixes, or Proteinase K. Our global reach and systematic tracking of the value chain – from the source of our raw materials to the loading docks of our customers – constitute a robust foundation upon which you can build innovations to improve patient care.

Given our investment into expanding our capacity, into streamlining our upscale processes, and into strengthening our infrastructure, that promise of reliability and security for molecular diagnostics reagents is future-proofed for the aspects that are under our control. Now more than ever, we are fully equipped and ready to deliverin the face of any challenge that tomorrow may bring.
