CST, 68864SF, CD248 (E9Z7O) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying CD248. Validated for WB,IHC,IHC,IF. Highly specific and rigorously validated in-house, CD248 (E9Z7O) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #68864) is ready to ship. Product Usage Information This product is the carrier free version of product #47948. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 47948 Storage Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Specificity / Sensitivity CD248 (E9Z7O) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total CD248 protein. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro403 of human CD248 protein. Background CD248, also known as Endosialin and TEM1, is a stromal cell marker expressed on activated mesenchymal cells including fibroblasts and pericytes. Not normally detectable in most adult tissues, it is highly expressed in lymphoid tissues during development, and in disease states where increased stromal cell proliferation and migration are evident (1-3). CD248 is known to be upregulated in breast cancer, brain tumors (4-6), and other malignancies including sarcoma (12), and it has been implicated in sprouting angiogenesis and vasculogenesis (7). It is thought that the CD248 gene is upregulated in response to hypoxic conditions in the tumor environment through HIF2 activation (8). Interestingly, CD248 is found to be highly expressed in activated fibroblasts. In liver fibrosis for example, CD248 marks the Hepatic Stellate Cells, the activated cells responsible for matrix production (9,10). In kidney fibrosis, CD248 marks the key effector cells within the fibrotic stroma including pericytes, myofibroblasts, and stromal fibroblasts (11), and in Idiopathic Pulmonary Fibrosis, CD248 may be a marker for severity of disease (12). CD248 has become a target of interest for pharmaceutical intervention in a wide scope of diseases (13).
