Alpha Donor beads coated with nickel chelate. These beads can be used to capture His-tagged proteins and biomolecules, and can be used in conjunction with AlphaScreen, AlphaLISA, or AlphaPlex Acceptor beads to create no-wash assays for:
In a typical Alpha assay, 1 mg of Donor beads is sufficient to run 1,000-2,000 wells using a 25 µL reaction volume. Bead concentration can be adjusted for optimal performance.

The interactions and bindingof proteins are implicated in a large number of biological processes. The needfor an efficient, highly sensitive assay to study large protein interactions is increasingly important. Alpha Technology is a highly flexible, homogeneous, no-wash assay ideal for the measurement of protein interactions and complexes as large as 200 nm in size
AlphaScreen Nickel Chelate Donor Beads at 5 mg/mL in 25 mM Hepes, pH 7.4, 100 mMNaCl supplemented with 0.05% Proclin-300 as a preservative.
Alpha has been used to study a wide variety of interactions, including protein:protein, protein:peptide, protein:DNA, protein:RNA, protein:carbohydrate, protein:small molecule, receptor:ligand, and nuclear receptor:ligand interactions. Both cell-based and biochemical interactions have been monitored, and applications such as phage display, ELISA, and EMSA (electrophoretic mobility shift assay) have been adapted to Alpha.
This guide presents the simple conversion of an ELISA or other immunoassay to an AlphaLISA® immunoassay.
AlphaScreen® and AlphaLISA® are bead-based assay technologies used to study biomolecular interactions in a microplate format. The acronym “Alpha” stands for Amplified Luminescent Proximity Homogeneous Assay. The assay does not require any washing steps. Binding of proteins or other binding partners captured on the beads leads to an energy transfer from one bead to the other, ultimately producing a luminescent signal.
