Properties

Applications

Our Abpromise guarantee covers the use of ab34686 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA Use a concentration of 0.2 - 1 µg/ml.
WB Use a concentration of 1.67 - 10 µg/ml. Detects a band of approximately 11 kDa.
IHC-P Use a concentration of 2.5 - 25 µg/ml.

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.

Anti-S100 antibody images

  • ab34686 staining S100 in Rat nerve tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 10% serum for 30 minutes at 25°C; antigen retrieval was by heat mediation in a 10mM citrate buffer, pH 6.0. Samples were incubated with primary antibody (1/250 in PBS + 1x casein) for 1 hour at 25°C. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody.

    Observed band size : 11 kDa (why is the actual band size different from the predicted?)
  • Ab34686, at a 1/500 dilution, staining S100 in mouse brain tissue by immunohistochemistry. The tissue was formalin fixed and embedded in paraffin. Dark nuclear staining is observed within basket cells located near the Purkinje cells in the cerebellum.
  • Ab34686, at 1/500 dilution, staining S100 in formalin fixed and paraffin embedded human brain astrocyte tumor tissue by immunohistochemistry.
