产品详情

分子别名: B7H4; B7-H4; B7S1; B7h.5; B7x; FLJ22418; VTCN1; PRO1291
蛋白长度: Phe29-Ala258
表达系统: HEK293
理论分子量: The protein has a predicted MW of 26.92 kDa. Due to glycosylation, the protein migrates to 50-65 kDa based on Bis-Tris PAGE result.
纯度: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
内毒素: Less than 0.1 EU per μg by the LAL method.
缓冲液 / 制剂: Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
状态: 冻干粉
储存条件: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
复溶建议: Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

背景介绍

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.
