  • Confidence in results: Achieves results with sensitivity down to >0.05%
  • Efficient workflow: Utilize a single universal mix and one workflow for both screening and monitoring, reduces hands-on time in as little as 45 minutes, and delivers next-day sequencing results
  • Simplified analysis: User-friendly software simplifies chimerism assessment, enables flexible data presentation, and provides longitudinal tracking, all within one dedicated software
  • Expert support: Our dedicated team of scientists and specialists are available to answer your questions, interpret data, and guide you towards optimal use of One Lambda Devyser NGS Assay

What is the One Lambda Devyser Chimerism assay?

The next generation of chimerism testing

Designed to provide accurate and sensitive detection of microchimerism levels in stem cell transplant samples, the One Lambda Devyser Chimerism NGS Assay is a post-transplant monitoring solution that is perfect for HLA and molecular core labs associated with HSCT Programs. It offers a fast and repeatable workflow from patient sample to report and a unified workflow for screening and monitoring. One tube per sample avoids any need for sample splitting, and the single measurement method is independent of mixed chimerism levels. Leveraging next-generation sequencing (NGS) technology, our assay offers an unparalleled limit of detection of 0.05%, enabling the identification of even the smallest changes in chimerism status.

How does One Lambda Devyser Chimerism assay work?

Seamless workflow for maximum efficiency

Our One Lambda Devyser Chimerism NGS Assay offers a seamless workflow that requires as little as 45 minutes of hands-on time, delivers results within 24 hours, and helps ensure maximum efficiency in your laboratory. By utilizing a single protocol, you can easily perform both screening and monitoring together and eliminate the need for sample-specific primers and patient-specific marker tracking. The universal reagent mix allows for cost-effective testing, reducing reagent wastage and the need to keep multiple reagents in stock.


Highly accurate results with unmatched sensitivity

The One Lambda Devyser Chimerism NGS Assay combines the sensitivity of real-time PCR analysis and the precision of STR based analysis. The unique 24-indel panel allows for accurate detection and monitoring of microchimerism, irrespective of mixed chimerism levels. With one tube per sample, there's no need for sample splitting, ensuring optimal sample integrity and reliable results.
