Drug Discovery Reagents

Drug discovery starts with an understanding of the basics of diseases and disease pathways. Throughout the process of unraveling the complexity of disease pathways, identifying and characterizing targets, high throughput screening, and lead optimization PerkinElmer has the assays you can count on.

PerkinElmer's drug discovery reagents cover a wide array of applications ranging from immunoassays platforms and kinase assays to reporter gene, cytotoxicity and cell proliferation assays. Our easy-to-use platforms provide greater sensitivity, wide dynamic range, and reduced background.

From basic science to high throughput screening and lead optimization, PerkinElmer drug discovery reagents provide easy-to-use next generation assays every step of the way.

Alpha Technology

Alpha is a homogeneous, bead-based assay platform offering several advantages over traditional ELISAs. This versatile, easy-to-use platform is suitable for a wide range of applications.

AlphaLISA®, AlphaLISA SureFire® Ultra, Alpha Screen®, AlphaPlex®, and Alpha kits and standalone reagents can be used to detect:

  • Proteins and phosphoproteins
  • Protein: protein interactions – both high and low affinity
  • Receptor-ligand interactions
  • DNA interactions
  • Post-translational protein modifications

TR-FRET Technology

TR-FRET combines the benefits of Time Resolved Fluorescence (TRF) with those of Forster Resonance Energy Transfer (FRET). PerkinElmer offers two TR-FRET technologies - HTRF® (Homogeneous Time Resolved Technology) and LANCE® (Lanthanide Chelate Excite) Ultra TR-FRET.

HTRF and LANCE Ultra kits and standalone reagents can be used to detect:

  • Proteins and phosphoproteins
  • Protein: protein interactions
  • Receptor-ligand interactions
  • Second messenger levels

TRF Technology

DELFIA® (Dissociation-Enhanced Lanthanide Fluorescence Immunoassay) is a washed based, time-resolved fluorescence (TRF) detection platform that utilizes fluorescent lanthanide chelates rather than other fluorophores. While superficially quite similar to an ELISA, DELFIA® comes with additional benefits. DELFIA® has a stable, time-resolved fluorescent signal which improves the assay dynamic range.

DELFIA® kits and standalone reagents can be used to detect:

  • Proteins and phosphoproteins
  • Protein: protein interactions
  • Cytotoxicity
  • Cell proliferation

Radiometric Assays

Radiometric detection remains the most sensitive assay today. We offer scintillation proximity assays (SPAs) and radiolabeled ligands for ligand binding studies, plus a vast array of radiochemicals for all your research needs.

Our products support a range of radiometric assays, including:

  • Scintillation Proximity Assays (SPA)
  • Receptor-Ligand binding assays – using either tritiated and iodinated compounds


PerkinElmer offers a range of ELISA alternative immunoassay technologies that enable selection of the optimal immunoassay platform for your requirements. From sample compatibility to sample volume, throughput, detectable range, signal window, signal stability, reproducibility, automation compatibility, and desired speed of results, PerkinElmer offers immunoassay technology platforms, pre-configured kits, and customizable reagents for superior results.

Better Microplates Means Better Results

A microplate is a critical part of your discovery process. Microplates have the capability to generate valuable, information-rich data that bring great insights into discovery screening.

Microplate planarity and inaccurate data collection are common issues caused by microplates that are not carefully designed for the unique challenges of sample screening which can result in missed data points, sample re-screening, missed project timelines, and ultimately higher costs.
