The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration. Predicted molecular weight: 10 kDa.
Use at an assay dependent concentration.
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.
