Produced using Abcam’s RabMAb® technology. RabMAb® technology is covered by the following U.S. Patents, No. 5,675,063 and/or 7,429,487.
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. Binds to and initiates the activation of STK38 by releasing autoinhibitory intramolecular interactions within the kinase. Interaction with AGER after myocardial infarction may play a role in myocyte apoptosis by activating ERK1/2 and p53/TP53 signaling.
Tissue specificityAlthough predominant among the water-soluble brain proteins, S100 is also found in a variety of other tissues.
Sequence similaritiesBelongs to the S-101 family. Contains 2 EF-hand domains.
Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 A-375 (Human malignant melanoma cell line) cells labeling S100 beta with purified ab52642 at 1/100 dilution, followed by Goat anti rabbit IgG (Alexa Fluor® 488) ab150077 secondary antibody at 1/500 dilution (green). The nuclear counter stain is DAPI (blue). The negative control is as follows; ab52642 at 1/100 dilution followed by ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution.
S100 beta was immunoprecipitated from Human fetal brain with purified ab52642 at 1/50 dilution. Western blot was performed from the immunoprecipitate using ab52642 and Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated was used as secondary antibody at 1/1000 dilution.
Blocking and dilution buffer and concentration: 5% NFDM/TBST.

Unpurified ab52642 staining S100 beta in Human spiral ganglion tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 1% BSA for 30 minutes at room temperature; antigen retrieval was by heat mediation in citrate buffer, pH6.0. Samples were incubated with primary antibody (1/200 in PBS-T + 1% BSA) for 12 hours. An Alexa Fluor® 488-conjugated Donkey anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody.
