S100A9 / MRP14 antibody was raised against e. coli-derived human S100A9 recombinant protein (Position: T2-P114). Human S100A9 shares 59.8% and 64.5% amino acid (aa) sequence identity with mouse and rat S100A9, respectively.
Calprotectin (S100A8/9) is predominantly expressed in myeloid cells. Except for inflammatory conditions, the expression is restricted to a specific stage of myeloid differentiation since both proteins are expressed in circulating neutrophils and monocytes but are absent in normal tissue macrophages and lymphocytes. Under chronic inflammatory conditions, such as psoriasis and malignant disorders, also expressed in the epidermis. Found in high concentrations at local sites of inflammation or in the serum of patients with inflammatory diseases such as rheumatoid, cystic fibrosis, inflammatory bowel disease, Crohn's disease, giant cell arteritis, cystic fibrosis, Sjogren's syndrome, systemic lupus erythematosus, and progressive systemic sclerosis. Involved in the formation and deposition of amyloids in the aging prostate known as corpora amylacea inclusions. Strongly up-regulated in many tumors, including gastric, esophageal, colon, pancreatic, bladder, ovarian, thyroid, breast and skin cancers. .
IHC: Antigen retrieval by boiling the paraffin sections in 10 mM citrate buffer, pH6.0, for 20 minutes is required for the staining of formalin/paraffin sections.
Lyophilized from 7.1 mM sodium phosphate, 77 mM NaCl, 2.5% BSA, 0.025% sodium azide
