Build your own assay for quantitative detection of target analyte in cell lysate, cell supernatant, tissue extract, serum, plasma, blood, and other sample types using DELFIA time-resolved fluorescence wash-based technology. DELFIA (Dissociation-enhanced lanthanide fluorescence immunoassay) TRF (time-resolved fluorescence) technology is a highly-sensitive wash-based immunoassay platform which utilizes a lanthanide chelate to reduce background and improve assay dynamic range. DELFIA offers significant advantages over traditional ELISA, while keeping a similar workflow:

 High sensitivity
 Wide dynamic range
 Superior stability
 Proven technology


DELFIA Toolbox Kits allow you to build your own DELFIA assay using your preferred antibody against the analyte of interest, bringing you the ability to painlessly switch your traditional ELISA to one with a wider dynamic range, higher sensitivity and great signal stability. These kits contain:


 DELFIA Europium-labeled anti-goat IgG
 DELFIA Wash Concentrate
 DELFIA Assay Buffer
 DELFIA Enhancement Solution
 DTPA Purified BSA (7.5%)
 96-well Stripwell Plates or ½AreaPlates (high bind for direct coating of antibody)
