It is present in a wide variety of normal adult tissues and fetal tissues, and has a role in bone, tooth and heart development and function. Studies show that periostin is overexpressed in a broad range of human cancer types, including lung, ovary, breast and colon cancers. Recent evidence reveals that periostin is expressed by fibroblasts in the normal tissue and in the stroma of the primary tumour, and it is required to allow cancer stem cell maintenance.\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: human\nHost \/ Isotype: Rabbit \/ IgG\nClass: Polyclonal\nType: Antibody\nImmunogen: CatNo: Ag27145 Product name: Recombinant human POSTN protein Source: e coli. -derived, PGEX-4T Tag: GST Domain: 473-669 aa of BC106710 Sequence: MEKGSKQGRNGAIHIFREIIKPAEKSLHEKLKQDKRFSTFLSLLEAADLKELLTQPGDWTLFVPTNDAFKGMTSEEKEILIRDKNALQNIILYHLTPGVFIGKGFEPGVTNILKTTQGSKIFLKEVNDTLLVNELKSKESDIMTTNGVIHVVDKLLYPADTPVGNDQLLEILNKLIKYIQIKFVRGSTFKEIPVTVY Predict reactive species\nFull Name: periostin, osteoblast specific factor\nGenBank Accession Number: BC106710\nGene Symbol: Periostin\nGene ID (NCBI): 10631\nRRID: AB_2880975\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Antigen affinity purification\nUNIPROT ID: Q15063\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
