Your scientists are your most valuable resource. But when they have to develop their own assays and reagents, they have less time to spend investigating and innovating. That's the thinking behind our OnPoint Custom and Reagent Services – the complete solution for accelerating and simplifying life science research and drug discovery.

Let us help you develop assays for an array of functional applications including but not limited to:

  • Biotherapeutics
  • Epigenetics
  • General biomarker detection
  • GPCR
  • Kinase
  • Phosphatase
  • Protein: DNA interactions
  • Protein: RNA interactions
  • Protein: protein interactions

The OnPoint Assay Development Process

  • OnPoint Scientific Consultation - Our Assay Development Scientists conduct a technical assessment, discussing assay and reagent specifics and performance criteria.
  • Assay and Reagent Development Proposal - The OnPoint team creates a customized quote and service proposal for your project, including a detailed description of the assay development plan, deliverables and estimated timelines.
  • Development and Optimization - The team provides preliminary feedback on progress and reports key milestones and any suggested changes or additions to the project plan, which are only implemented with your approval.
  • Complete Technology Transfer - The transfer process includes
    • Proof-of-concept report
    • Training on your assay, in your lab by one of our expert Drug Discovery Application Specialists

DELFIA® Buffers Guide

DELFIA is a heterogeneous time-resolved fluorometric assay method in which an enhancement step assures high sensitivity andwide response range. To achieve the best results in a DELFIA assay, the optimal buffer composition should be chosen. A numberof ready-to-use buffer products are available as catalog items, or users may prepare their own formulations based on the following guidelines.
