The ELISA reaction relies on the specific interaction between antibodies and antigens. Wells in ELISA plates are coated with test-specific antigens. After a wash cycle removes excess and non-specifically bound antibodies, a secondary antibody with an enzyme detects the generated immune complex. Another wash cycle removes excess of the enzyme conjugate before a colorless substrate is added and converted into a colored product by the enzyme. The color intensity is measured photometrically. It is proportional to the antibody activity in the sample. A standardized master curve is used for evaluation. Antibody activities of unknown samples are derived from their optical signals via the recalibrated standard curve.
For over 35 years, ORGENTEC Diagnostika GmbH and Zeus Scientific have been developing, producing and distributing ELISA test systems for autoimmune- and infection diagnostics. The experience of these companies is now complementing the Sebia ELISA portfolio. This product line already includes more than 50 classical ELISA kits and more than 100 corresponding test systems for automated processing with Alegria.
