Simple Conversion of ELISA to PerkinElmer’s High Sensitivity DELFIA Technology
2 August 2017

Dissociation-enhanced lanthanide fluorescent immunoassay (DELFIA®) technology is very powerful, providing highly sensitive and robust immunodetection based on time-resolved fluorescence (TRF). This detection method, similar to ELISA, is special due to its unique chemical properties of lanthanide metals that give DELFIA several distinct advantages over ELISA technology. DELFIA affords a combination of improved sensitivity, wider dynamic range, and easily developed signal that does not require a stop solution and is stable and long-lasting, allowing samples to be read long after assay completion.
