  • Simple custom assay development for both protein and circulating nucleic acid detection


The Quanterix SR-Plex Ultra-Sensitive Biomarker Detection System is the latest instrument powered by Simoa technology, offering researchers access to ultra-sensitive biomarker detection capabilities in a compact and affordable system. The SR-Plex is designed for multiplex detection of up to six analytes per well, with low volume requirements to increase productivity and throughput, while conserving your precious samples. A menu of over 70 Simoa assay kits are available to measure critical biomarkers with 1000X higher sensitivity than standard immunoassay methods, enabling detection of both normal and acute levels with high precision across a range of sample types. 
The Quanterix SR-Plex also provides researchers with the additional flexibility to design assays to detect both protein and nucleic acid biomarkers direct from blood without the need for error-prone complex pre-analytical extraction and amplification steps. This unique capability enables measurement of ultra sensitive nucleic acid levels, including miRNA, without PCR.
