B7-H4 Protein, Human, Recombinant (His & Avi)

B7-H4, also known as B7x and B7S1, is a 50-80 kDa glycosylated member of the B7 family of immunomodulatory proteins.B7-H4 is up-regulated in several carcinomas in correlation with tumor progression and metastasis. A soluble form of B7-H4 is elevated in the serum of ovarian cancer, renal cell carcinoma, and rheumatoid arthritis patients, also in correlation with advanced disease status .

种属	Human
表达系统	HEK293
标签	C-His-Avi
蛋白编号	Q7Z7D3-1
别名	B7H4, B7x, VTCN1, PRO1291, B7S1, B7h.5, FLJ22418, B7-H4
蛋白构建	Recombinant Human B7-H4 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Phe29-Ala258.[Accession \|Q7Z7D3-1]
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 28.2 kDa. Due to glycosylation, the protein migrates to 52-68 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.
