Applicability of DELFIA Fluorescence-Based Immunoassay Technology to Detect and Quantitate Biomarker

Introduction

DELFIA® (Dissociated-Enhanced Lanthanide Fluorescent Immunoassay) TRF is a proven, robust immunodetection platform with over 20 years of history. DELFIA has a similar assay principle and workflow to that of a traditional ELISA, but with the added benefits of a stable, time-resolved fluorescent signal, and improved assay dynamic range.

Download this application note to see how DELFIA time-resolved fluorescence (TRF) technology serves as an alternative to traditional ELISA with a wider dynamic range and superior signal stability for quantitation of biomarkers in complex sample types, including serum, plasma, and blood.
