Alpha Donor beads coated with Protein A. These beads can be used to capture antibodies and Fc-fusion proteins that bind Protein A, and can be used in conjunction with AlphaScreen, AlphaLISA, or AlphaPlex Acceptor beads to create no-wash assays for:

  • Analyte detection assays
  • Biomarker detection assays
  • Clone selection assays
  • Protein-protein interaction assays
  • Protein detection assays
  • Enzymatic assays
  • Other immunoassays

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.
