      Background InformationS100 calcium binding protein A12, also known as S100A12, EN-RAGE, and calgranulin C, is a proinflammatory protein with significant potential as a biomarker. It is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. The member S100A12 is proposed to be involved in specific calcium-dependent signal transduction pathways and its regulatory effect on cytoskeletal components may modulate various neutrophil activities. It has been reported to be secreted by activated granulocytes and binds to the receptor for advanced gycation end products, which induces NfkappaB-dependent activation of endothelium (Foell et al., 2003). S100A12 is strongly expressed in inflamed synovial tissue typical in rheumatoid and psoriatic arthritis and may also prove an excellent biomarker for Inflammatory bowel disease (Kaiser et al., 2007). S100A12 protein may also be involved in chronic inflammation in atherosclerotic lesions including those of Type II diabetics (Kosaki et al. 2004) and the acceleration of atherosclerosis in hemodialysis patients (Mori et al., 2009).

      ApplicationThis Anti-S100A12 Antibody is validated for use in ELISA, IH, WB for the detection of S100A12.
      Key Applications
      • ELISA
      • Immunohistochemistry
      • Western Blotting
      Application NotesWestern blot: 1:1,000-1:10,000 on recombinant human S100A12.
      Immunohistochemistry: fesh frozen, acetone fixed sections 1:100-1:500 using ABC enzymatic detection methods (Srikrishna, G. et al, 2005). Other fixation conditions not yet tested.
      ELISA: 1:10,000-1:100,000 against the recombinant human S100A12.
      It is expected that the antibody will also work for immunohistochemistry.

      Optimal working dilutions must be determined by the end user.
      Biological Information
      ImmunogenFull length recombinant His-tagged human S100A12 that was expressed in E. coli and purified by Ni-NTA affinity chromatography prior to immunization.
      SpecificityBy western blot this polyclonal antibody recognizes a band at ~10-11 kDa under reducing conditions. A dimer can be sometimes be seen at ~ 21 kDa using recombinant human S100A12. Antibody was affinity purifed over immobilized S100A12 prior to vialing.
