IP 1/10 - 1/100.
Flow Cyt 1/10 - 1/100. ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
ICC/IF 1/100 - 1/250.
  • Application notesIs unsuitable for IHC-P.
  • Target

    • FunctionWeakly binds calcium but binds zinc very tightly-distinct binding sites with different affinities exist for both ions on each monomer. Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites.
    • Tissue specificityHighly prevalent in heart. Also found in lesser quantities in skeletal muscle and brain.
    • Sequence similaritiesBelongs to the S-100 family.
      Contains 2 EF-hand domains.
    • Cellular localizationCytoplasm.
