The MESO QuickPlex SQ 120 instrument has increased the accessibility of researchers and scientists to Meso Scale Discovery's (MSD) multi-array technology, a proprietary combination of patterned arrays and electrochemiluminescence detection that results in high sensitivity, speed, dynamic range and convenience.One of the fastest growing technologies in the immunoassay field, electrochemiluminescence (ECL) is driving research in areas including neurobiology/neurodegeneration, immunogenicity and intracellular signalling. The SQ 120 provides high sensitivity and dynamic range, simple protocols, rapid and continuous reads and fast, well-organised results via Discovery Workbench assay analysis software. The instrument requires no user calibration or maintenance, no complicated fluidics and no between-read cleaning.MSD MULTI-ARRAY plates are available as single-spot (single-assay) plates and as MULTI-SPOT plates with patterned spot arrays in each well. MULTI-SPOT plates measure multiple analytes simultaneously in a single well, increasing throughput and enabling novel assay panels. The instrument has a wide menu of commercially available assay kits and a full line of components and reagents for developing in-house assays.Exclusively available for use with the MSD instruments, V-PLEX validated immunoassays deliver reproducible results to support demanding long-term studies. The extensive menu of over 100 assay kits provides many options for the conscientious researcher who is looking for increased sensitivity and dynamic range, as well as lot-to-lot consistency over the life of their longitudinal study.Whether multiplexing biomarker and cytokine assays, testing for immunogenicity or toxicity or developing assays, users will appreciate the fast, simple assay processing, low sample volume requirements and minimal consumption of reagents that the instrument make possible.
