AlphaScreen Unconjugated Donor Beads, 50mg

Alpha Unconjugated Donor beads are provided so that you can conjugate your biomolecule-of-interest (antibody, protein, peptide, etc.) to create your own Alpha Donor beads for use in Alpha no-wash assays.

For research use only. Not for use in diagnostic procedures. All products to be used in accordance with applicable laws and regulations including without limitation, consumption & disposal requirements under European REACH regulations (EC 1907/2006).

These beads can be used in conjunction with AlphaScreen, AlphaLISA, or AlphaPlex Acceptor beads to create no-wash assays for:

  • Analyte detection assays
  • Protein-protein interaction assays
  • Protein-DNA interaction assays
  • Protein-RNA interaction assays
  • Protein-small molecule interaction assays
  • Protein detection assays
  • Antibody detection assays
  • Antibody binding assays
  • Enzymatic assays
  • Immunogenicity studies

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.
