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:

Application Note

A Novel DELFIA Time-Resolved Fluorescence Biomarker Detection Assay with Superior Performance to Conventional ELISA

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 TRF outperforms ELISA as a robust assay providing high sensitivity, superior signal stability, and a wider dynamic range.

Measuring Host Cell Protein Contamination in Recombinant Therapeutic Protein Production by DELFIA TRF as an Alternative to ELISA

Along with the expression of the protein of interest, host cells release additional proteins (Host Cell Proteins, HCPs) into the supernatant which must be removed from drug products because they pose a risk of affecting drug quality, safety and efficacy.

The potential immunogenicity of biologics due to HCP contamination is a large risk, hence the need for accurate measurement to track the reduction of HCPs throughout the manufacturing process.

In this application note, you will learn:

  • Why DELFIA® TRF assay technology is well suited for measuring HCPs through the biologics manufacturing process
  • How to run a host cell protein assay from an example assay to detect Chinese Hamster Ovary (CHO) HCPs
  • Benefits DELFIA can provide over traditional ELISAs, saving costs and potentially limited sample amounts
  • Comparison data between an ELISA and DELFIA assay
