MSD S-PLEX assays are optimized for rapid, ultrasensitive detection of analytes from a single, small-volume sample. S-PLEX technology enables the detection and quantification of low-abundance analytes that are unmeasurable by traditional immunoassay methods. S-PLEX assays also allow researchers to conserve sample volumes—a critical advantage when working with limited biological specimens.

MSD S-PLEX assays are:

• Ultrasensitive: detect proteins in the fg/mL range, enabling the detection of low-abundance markers and conservation of sample.
• Highly specific: ensuring that the signals you detect accurately reflect your target analytes without interference from cross-reactivity or background noise.
• Available as Multiplexes: saving you additional sample volume and maximizing the amount of data per sample.
