S-PLEX: TrueSensitivity, Simple Execution

S-PLEX: Discover TrueSensitivity

S-PLEX is MSD’s ultrasensitive 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. Detection limits in the low femtogram/mL range are common. These low detection limits enable the measurement of analytes at lower concentrations, reduce sample volume required, and reduce the amount of critical reagents used. 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 part of a new multiplex panel that includes nine biomarkers. Using the quick links below, learn more about S-PLEX technology, S-PLEX publications, and S-PLEX sample testing services.

NEW S-PLEX Multiplex Panel

The panel can be used to measure up to nine biomarkers together or select analytes of interest to create a custom multiplex.
