Drug discovery is a complex, costly and time-consuming undertaking. For research scientists, screening potential candidates is where the journey begins.
Your job is to move from target to hit to candidate quickly and efficiently – with as little wasted resources as possible. Our drug discovery screening reagents do just that. Whether you are doing high throughput screening or focused screening, we offer a wide range of validated reagents and kits in Alpha chemiluminescent, LANCE® TR-FRET, DELFIA® TRF, and other assay technologies to suit you screening assay needs.
Accelerate your workflow with our drug discovery screening reagents while getting consistent, accurate and physiologically relevant results.
Virtually anything can be measured with Alpha Technology quickly and easily, including enzymes, receptor-ligand interactions, low-affinity interactions, second messenger levels, DNA, RNA, proteins, protein post-translational modifications, protein:protein interactions, peptides, sugars and small molecules.

From assay development to primary and secondary screening, LANCE Ultra Technology provides researchers with robust and easy-to-use assays adaptable to a variety of targets on a broad range of multimode detectors, with the fastest time-to-results in a commercially-available TR-FRET assay.
Homogeneous dispense-and-read technology
384-well and 1536-well formats
LANCE and LANCE (LANthanide Chelate Excitation) Ultra are our TR-FRET (time-resolved fluorescence resonance energy transfer), homogeneous (no wash) technologies. One binding partner of interest is labeled with a donor fluorophore (a LANCE Europium chelate) and a second one is labeled with an acceptor fluorophore (ULight™ dye). Upon excitation at 320-340 nm, energy can be transferred from the donor Europium chelate to the acceptor fluorophore if sufficiently close for FRET (~10 nm). This results in the emission of light detectable at 665 nm.
DELFIA (Dissociation-Enhanced Lanthanide Fluorescence Immunoassay) is a proven, robust immunodetection platform based on time-resolved fluorescence (TRF) detection. This detection method, coupled with the unique chemical properties of lanthanide chelates, makes DELFIA a superior alternative to conventional ELISA for research, drug discovery, and clinical applications.
DELFIA offers a combination of high sensitivity, wide dynamic range and long-lasting stability that traditional ELISA cannot match.
Whether your assay requires the sensitivity provided by high signal intensity, or the flexibility of an extended signal half-life, PerkinElmer provides a solution. Choose from one of three luciferase detection systems: neolite, britelite plus, or steadylite plus depending on the specific requirements of your experiment.
No more washing – just add your lites reagent of choice, mix, incubate, and read
Hassle-free storage – all lites reagents are designed for extended storage at 2-8 °C (no -20 °C storage required)
Odor-friendly, eliminates hood work – lites products do not contain DTT and do not have the hazards and repugnant odor typical of conventional luciferase detection systems
Excellent Z’ values – superior S/B ratios allow for excellent Z’ values in antagonist and agonist studies
For fast, reliable detection of ATP for cell quantitation, ATPlite 1step and ATPlite are innovative technologies that measure cell proliferation and cytotoxicity in mammalian cells based on the detection of ATP using firefly luciferase.
ATPlite 1step – Highest sensitivity
True “mix and measure” continuous processing
Ultra high sensitivity, 3 times more light output than ATPlite
Short equilibrium time for faster processing
Signal half-life of 30 minutes
ATPlite – Convenient, extended Signal
2-step format, non-separation assay for time course studies; lysate can be stored frozen and tested later
