Meso Scale Discovery (MSD) V-PLEX Kits

MSD electrochemiluminescence (ECL) technology is a highly sensitive, multiplex immunoassay platform used for the quantitative detection of antigen‑specific antibodies in infectious‑disease serology. The assay employs multi‑spot plates with integrated carbon electrodes that provide higher binding capacity and reduced background compared with conventional polystyrene ELISA plates. Detection antibodies are conjugated to a ruthenium‑based SULFO‑TAG label, which emits light upon electrochemical stimulation. The emitted signal is captured by a high‑resolution CCD imaging system, enabling precise quantification across a broad dynamic range.

 

In VisMederi, MSD technology is widely applied to the assessment of antibody responses against respiratory and emerging viral pathogens, including SARS‑CoV‑2, influenza A and B viruses, RSV, and orthopoxviruses such as Monkeypox and Vaccinia viruses (Correlation between microneutralization test and a multiplexed immunoassay for evaluation of monkeypox and vaccinia virus antibodies before and after smallpox vaccination), through the detection of antibodies targeting specific viral antigens. The multiplex format enables the simultaneous measurement of antibodies against multiple antigens or pathogens within a single sample, substantially reducing sample volume requirements and assay time.

 

Other key applications implemented in VisMederi include respiratory virus Ig detection, viral panels, and a wide range of multiplex assays such as customizable 29-plex cytokine panels, chemokine panels, and proinflammatory markers, alongside human biomarker profiling. The platform also supports specialized panels for metabolic pathways, neuroinflammation, vascular injury, and angiogenesis, providing a comprehensive solution for immunological and translational research.

 

Compared with conventional single‑plex serological assays, MSD technology offers enhanced sensitivity, wider dynamic range, improved precision, and high‑throughput multiplex capability, making it particularly suitable for vaccine immunogenicity evaluations, longitudinal immune monitoring, and large‑scale sero‑epidemiological studies.
