BGN (biglycan), also called proteoglycan I (PGI), which belongs to the family of proteoglycans called small leucine-rich proteoglycan (SLRP). This protein is composed of characteristic leucine-rich repeat motifs located centrally. These motifs are linked by disulfide bond stabilized loops. It is predominantly expressed in tissues of mesenchymal type, and is found in the cell surface or in the pericellular matrix.
Synonyms: Anti-Biglycan precursor antibody produced in rabbit; Anti-Bone/cartilage proteoglycan I antibody produced in rabbit; Anti-PG-S1 antibody produced in rabbit
Storage: -20C
Application: Anti-BGN antibody produced in rabbit is suitable for use in measuring the concentration of biglycan by sandwich ELISA method.Anti-BGN antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: BGN (biglycan) gene encodes a leucine-rich, pericellular matrix proteoglycan that functions in the assembly of collagen fibrils and muscle regeneration. It belongs to the decorin family of proteins and contains two chains of chondroitin sulfate. It interacts with transforming growth factor ß and may function in regulating its activities. The distribution of this protein indicates that it may be involved in the physiology of the neuromuscular junction, and morphogenesis and differentiation of tissues. The protein functions as an endogenous ligand for Toll-like receptors, TLR4 and TLR2, that are involved in innate immunity. It enhances inflammation via TLR4 and TLR2 signaling, leading to the synthesis of TNF-a (Tumor necrosis factor-a) and MIP-2 (macrophage inflammatory protein-2).
