How does mesoscale discovery work?
How the Meso Scale Discovery Platform (MSD-ECL) Works. The MSD-ECL platform uses electrochemiluminescent labels that are conjugated to detection antibodies. These labels generate light when stimulated by electricity in the appropriate chemical environment, which can then be used to measure key proteins and molecules.
How does sulfo tag work?
The labels are called SULFO-TAG, and allow for ultra-sensitive detection. Electricity is applied to the plate electrodes by an MSD instrument leading to light emission by SULFO-TAG labels. Light intensity is then measured to quantify analytes in the sample.
Is MSD an Elisa?
MSD (Meso Scale Discovery) is a method similar to ELISA except MSD uses electrochemiluminescence (ECL) as a detection technique as opposed to a colormetric reaction employed by ELISA. Meso Scale Discovery has developed proprietary technology for the measurement of molecules in biological samples.
What is an MSD plate?
MSD offers a wide range of plates specifically designed for use with MSD instruments. These plates incorporate electrodes in the bottom of each well to enable high-performance electrochemiluminescence immunoassays.
What is electrochemiluminescence detection?
Electrochemiluminescence (ECL) sensors are a combination of electrochemistry and measurement of visual luminescence. When a potential is applied onto an electrode, the electrode surface is excited. So an electron transfer is produced between molecules, and the resulting emitted light is measured.
What is electrochemiluminescence immunoassay?
Electrochemiluminescence immunoassay (ECLIA) is a quantitative method for measurement of antigen or antibody based on the change in electrochemiluminescence (ECL) signal before and after immunoreaction.

What is an MSD instrument?
Instruments. MSD offers instruments to fit every application, budget, and research environment. Our MESO SECTOR S 600 is ideal for applications requiring high information content and high throughput. The MESO QuickPlex SQ 120 is a compact, affordable multiplexing imager with exceptional performance.
Is MSD better than ELISA?
Our MULTI-ARRAY technology provides inherently better sensitivity and a broader dynamic range than ELISAs. This means fewer samples fall below the assay detection range….ELISA Comparison.
| ELISA | MSD | |
|---|---|---|
| Matrix effects | Yes | Greatly reduced |
| Simple protocols | No | Yes |
| Wash steps | Many | Typically 1–3 |
| Read times | Slow | Up to 960 results in 1 to 3 min |
Is there a difference between chemiluminescence and Electrochemiluminescence?
What is the Difference Between Chemiluminescence and Electrochemiluminescence? Chemiluminescence is the emission of light as a result of a chemical reaction. Meanwhile, electrochemiluminescence is the emission of light due to an electrochemical reaction occurring at an electrode surface.
What is electrochemiluminescence used for?
Electrochemiluminescence (ECL) assays can be used to detect and quantify the presence and toxicity of specific neurotoxin based on an ECL signal.
Is there a difference between chemiluminescence and electrochemiluminescence?
What is MSD immunoassay?
MSD immunoassays are based on a proprietary technology combining electrochemiluminescence and multiarray technology for detection of multiple proteins in a single sample. The majority of assays are sandwich-based and consist of a Multi-Spot microplate, where each spot is coated with unique capture antibodies.
What is the instrumentation of electrochemiluminescence?
Electrochemiluminescence (ECL) immunoassay is a process that uses labels designed to emit light when electrochemically stimulated. Light generation occurs when low voltage is applied to an electrode, triggering a cyclical oxidation and reduction reaction of a heavy metal ion, such as ruthenium.

What is electrochemiluminescence immunoassay test?
Recently, fully automated electro-chemiluminescence immunoassay (ECLIA) has been introduced claiming to be highly sensitive and specific. The aim of our study is to determine the diagnostic accuracy of anti-SARS-CoV-2 (ECLIA technique) for diagnosis of past infection with COVID-19 using RT-PCR as the golden standard.
