MSD combines the MULTI-ARRAY technology with ECL to deliver high density information. The multi-spot plates are available in 96- and 384 -well formats with up to 10 array spots per well. The high binding carbon electrodes of the assay plate enables easy attachment of a broad variety of reagents including antibodies and non-antibody molecules (carbohydrates, virus-like particles, peptides and membrane lysates). The surface is even eligible for spreading of living cells. The MSD SULFO-TAG™ label can be easily conjugated to any detection antibody. When the detection antibody comes in close proximity to the plate electrodes and electricity is applied, a series of reduction and oxidation reactions are set in motion. This results in light emission at approximately 620 nm and allows quantitative measurement of analytes in the sample.
