CST, 74495SF, Syndecan 1 (E7S6T) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying SDC1. Validated for WB,IF,F,F. Highly specific and rigorously validated in-house, Syndecan 1 (E7S6T) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #74495) is ready to ship. Product Usage Information This product is the carrier free version of product #52953. 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 # 52953 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 Syndecan 1 (E7S6T) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total syndecan 1 protein. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro178 of human syndecan 1 protein. Background Syndecans are a family of type 1 transmembrane heparan sulfate proteoglycans comprising four members in mammals (SDC1-4) (1) encoded by four syndecan genes. Syndecans are involved in embryonic development, tumorigenesis, and angiogenesis (2). The extracellular domain harbors attachment sites for heparan sulfate and chondroitin sulfate chains, facilitating interaction with an array of proteins, including a plethora of growth factors. In addition, the hydrophobic C-terminal intracellular domain can interact with proteins containing a PDZ domain (2). These interactions place syndecans as important integrators of membrane signaling (3). Syndecans undergo proteolytic cleavage causing the release of their extracellular domain (shedding), converting the membrane-bound proteins into soluble molecular effectors (4). Syndecan 1 (SDC1) is a specific marker for plasmacytic differentiation in hematologic disorders (5-7). This cell surface proteoglycan is also expressed in normal epithelial cells and tissues as well as various types of cancer tissues (8-11). The extracellular shed form of syndecan 1 remains soluble or accumulates in the extracellular matrix, where it binds growth factors, cytokines, and other extracellular matrix proteins (12,13). This binding activates signaling of bound growth factors or cytokines, which results in enhanced tumor growth, dissemination, angiogenesis, and osteolysis (14-17). As a result, the level of syndecan 1 protein and its shed form may serve as prognostic factors for a list of malignancies (6,18,19). Syndecan 1 has recently been found to be a critical mediator of macropinocytosis in pancreatic cancer (20).
