产品描述	Periostin/OSF-2 Protein, Human, Recombinant (aa 22-836, His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 92.1 kDa and the accession number is Q15063.

种属	Human
表达系统	HEK293
标签	C-His
蛋白编号	Q15063
别名	Periostin, POSTN, Fasciclin I-like, TRIF52, OSF-2, PNRP11-412K4.1, PN, PDLPOSTN, OSF2
蛋白构建	Recombinant Human Periostin/OSF-2 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asn22-Gln836.[Accession \|Q15063]
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	The protein has a predicted MW of 92.1 kDa. Due to glycosylation, the protein migrates to 93-100 kDa based on Tris-Bis PAGE result.

内毒素	Less than 1EU per μg by the LAL method.
缓冲液	Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
复溶方法	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
存储	-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
运输方式	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
研究背景	Periostin is a matricellular protein that is expressed in several tissues during embryonic development; however, its expression in adults is mostly restricted to collagen-rich connective tissues. Periostin is expressed only briefly during kidney development, but it is not normally detected in the adult kidney. Recent evidence has revealed that periostin is aberrantly expressed in several forms of chronic kidney disease (CKD), and that its expression correlates with the degree of interstitial fibrosis and the decline in renal function.
