S-PLEX is MSD’s ultra-sensitive assay platform. It can dramatically improve the sensitivity of immunoassays, reducing the lower limit of detection (LLOD) by 10- to 1000-fold over other assay methods. The S-PLEX SARS-CoV-2 Spike Assay has the essential components for an ultra-sensitive assay that measures SARS-CoV-2 Spike in a single-analyte format. For detailed instructions on running the SARS-CoV-2 Spike assay, please see the product insert in the "Documentation" tab below.
