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

Biomarker/cytokine detection

Detection and quantitation of molecular targets in serum, plasma, culture supernatants, cellular lysates, and other sample types.Convert troublesome traditional ELISAs to a far superior alternative - PerkinElmer's highly sensitive, homogeneous AlphaLISA platform for biomarkers and cytokines. Our exclusive AlphaLISA assay platform offers a wide dynamic range and easy automation for analysis of biomarkers, cytokines and other analytes. With AlphaLISA you can also shorten the time it takes you to run assays to less than 3 hours and benefit from small sample volumes (1-5 µL) to conserve precious sample.

Cell signaling

AlphaScreen SureFire, AlphaLISA SureFire Ultra, and Alpha SureFire Multiplex assay kits to measure protein phosphorylation in cell signaling pathways.

All-in-one-well alternative to Western Blotting
Flexibility to use cultured cell lines, stem cells and primary cells
Cost-effective and flexible – a single plate can accommodate any assay for any target
Great sensitivity and dynamic range
Easy automation
No harmful chemicals and non-radioactive, eliminating special reagent handling and disposal

Protein:protein interactions

Handle large biomolecular interactions with ease.

Ease-of-use: few addition steps, fast assay development
Broad range of affinities: detect strong or weak interactions, from pM to mM affinity
Distance: measure very large protein or antibody complexes – spanning up to 200 nm or more
High avidity: multiple binding sites on each bead enables use of nanomolar concentrations of antibodies or proteins, as well as use of low affinity binders
Conserve reagents: robust assays using nM concentrations of proteins/antibodies

Epigenetics

Highly sensitive no wash detection for measuring biochemical modification of peptides, proteins, histones, and nucleosomes. Cellular Detection Kits for rapid and direct detection of endogenous modification of epigenetic marks. Kits and reagents for writer, reader, and eraser assays.

Flexibility: Work with peptide or full-length protein substrates, or endogenous histones in cell-based format
Sensitivity: Robust and reproducible detection, even at low enzyme concentrations
Specificity: Reagents highly specific for the mark of interest
Simplicity: One-well, no-wash assay platforms amenable to automation and HTS
Validated: Detailed, ready-to-use protocols for over 30 epigenetic enzyme assays
