Custom Cell Line, Assay, and Protein Development Services

Your Target Biology, Our Expertise - Building a Better Assay Together

Cell-based assays are valuable tools throughout the drug discovery process. However, internal assay development can be expensive, requiring months to develop, tying up valuable internal resources, and in many cases can be technically challenging, further straining resources and timelines.

When an off-the-shelf option is not available, trust Eurofins DiscoverX custom assay development program to create assay and protein solutions that will deliver the quality results you expect. We offer a wide range of custom services to support drug development programs from discovery to lot release.

The Custom Assay Development (CAD) program at DiscoverX delivers tailor-made cell lines optimized for your requirements, enabling you to jump-start your drug discovery and development programs by solving your difficult assay’s development challenges, while saving you time, money, and resources. These customized assays have enabled hundreds of drug discovery programs at multiple companies globally through screening, lead optimization, and bioanalytical assay development.

PathHunter® Cell-Based Assay Development Services

PathHunter is a versatile cell-based assay platform, based on our proprietary EFC technology, successfully employed to develop validated assay solutions for over 700 targets spanning many target classes including GPCRs, Kinase, Checkpoint Modulators, NHRs, and more. Innovative applications of this core technology has enabled the development of robust, reliable, and high-throughput-friendly chemiluminescent assays to measure protein- interaction, protein translocation, secretion, and degradation, and receptor dimerization.

Path-Hunter cell-based technology format can query many types of interactions

  • Measure inducible and constitutive protein interactions
  • Measure protein translocation to various intracellular locations in a non-imaging HTS friendly assay
  • Accurately measure protein levels and stabilization 
 

InCELL Cell-Based Assays for Intracellular Target Binding

Universal Cell-Based Compound-Target Binding Assays

InCELL Pulse and InCELL Hunter are novel, yet powerful in vitro cellular ligand binding assay platforms that can be used to determine compound binding in a native cellular environment. Both platforms use enzyme fragment complementation technology to measure binding to the protein of interest and are powerful development tools to evaluate target engagement for intractable targets where other technologies have been unsuccessful.

InCELL - A simple cell-based assay for complex targets

  • Cell-based assau broadly applicable to several target classes
  • Target-specific response
  • Direct measure of intracellular binding to target
  • activity independent 
  • HTS compatible 
  • Bridge between in vitro binding assay and cellular functional assay

HitHunter® Biochemical Assay Development Services

The HitHunter Assay is a validated platform for biochemical quantification of second messenger signaling for cAMP and cGMP. Extension of the HitHunter principle to novel targets allows for investigation of protease and substrate activity.  HitHunter assays are formatted as competitive immunoassays, where analytes are detected in solution, without separation or wash steps, providing improved sensitivity and precision compared to conventional immunoassays.

HitHunter Biochemical Assay Development Services will work closely with you to develop a custom assay to detect protease and substrate activity or measure an analyte, providing comprehensive solutions where you need them most.

HitHunter biochemical technology has many advantages:

  • Develop novel assays for identifying analytes
  • Develop cleavage assays to test protease activity
  • Develop assays for use with primary cells
  • All assays will be HTS compatible,
  • Chemiluminescent detection - minimizes false positives from auto fluorescence
  • Reliable and robust assay with high Z' (0.75) HTS-friendly - adaptable to 1536 applications
  • Large assay windows
  • Broad application to multiple target classes
