S-PLEX is MSD’s ultrasensitive assay platform. It can dramatically improve the sensitivity of immunoassays, thereby reducing the lower limit of detection (LLOD) by 10- to 1000-fold over other assay methods. Detection limits in the low femtogram/mL range are common. These low detection limits enable the measurement of analytes at lower concentrations, reduce required sample volume, and reduce critical reagent usage. The S-PLEX assay format builds on MSD consumables and instruments and leverages MSD’s assay development expertise by using a procedure that is similar to other MSD assay methods.
S-PLEX assays are available either as singleplex kits or multiplex panels. Use the quick links below to learn more about S-PLEX technology, S-PLEX publications, and S-PLEX sample testing services.
