Biotherapeutics

Accelerate the development and marketability of your biotherapeutic drug with our isotyping, Fc-receptor binding, and bioprocess contaminant detection kits.

• AlphaLISA Kits: hIgG Fc

DELFIA Toolbox

DELFIA Toolbox reagents offer the flexibility to develop custom assays using the same ELISA-based or other preferred antibodies, specific to the analyte of interest.

• Kits for ELISA Conversion: Anti-Goat IgG, Anti-Mouse IgG, Anti-Rabbit IgG, Streptavidin
• Antibodies: Donkey anti-Rabbit, Mouse anti-Goat

Alpha Toolbox

Alpha Toolbox enables you to et up your own assay using ready-to-use Alpha beads for numerous capture solutions.

• AlphaLISA Acceptor Beads: Anti-human IgG (Fab specific)

Alpha Technology

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:protein interactions, peptides, sugars and small molecules.

• Ease-of-use: homogeneous, no-wash assay, with no separation steps
• Fast: results in 3 hours for most applications
• High sensitivity: detect down to femtogram levels of target
• Large dynamic range: 4-5 logs
• Compatible with many samples types: serum, plasma, cerbrospinal fluid (CSF), tissue extracts, cell culture supernatants, cell lysates, and more

Choose the Alpha solution that’s right for you

• AlphaLISA^® – when running large numbers of ELISA from the same sample or working with difficult matrix, serum or plasma
• AlphaLISA Surefire^™ Ultra^® and AlphaScreen SureFire – an excellent choice for studying pathways or phosphorylated proteins in whole cells, or studying endogenous receptors
• AlphaScreen^® – perfect for studying fusion-tagged proteins or protein:protein interactions, and for testing cAMP, phosphorylated peptides or samples in a simple matrix
• Alpha Toolbox – when your target doesn’t have an off-the-shelf kit, the toolbox gives you everything you need to create your own

DELFIA TRF

DELFIA^® (Dissociation-Enhanced Lanthanide Fluorescent Immunoassay) TRF technology combines the benefits of Time Resolved Fluorescence (TRF) with the use of lanthanide chelates for a highly sensitive, robust and reproducible assay format. With over 20 years of history, and thousands of publications, DEFLIA is ideal for simple to complex matrices and can be used for both biochemical and cell-based assays.

DELFIA TRF offers benefits over traditional ELISA including:

• Wider dynamic range
• Higher S:B
• Larger Stokes shift
• Superior stability
• Multiplexing capability

From immunoassays, to binding and enzymatic studies, to cytotoxicity and cell proliferation assays, our DELFIA TRF assays are sure to provide you with unmatched sensitivity, time and time again.

LANCE Ultra TR-FRET

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.

• No-wash/separation steps
• Homogeneous dispense-and-read technology
• Sensitive detection
• High reproducibility
• Faster time-to-results
• Easy automation
• 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.
