蛋白结构(Molecular Characterization)

This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 33.8 kDa. The protein migrates as 40-43 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记(Labeling)
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
内毒素(Endotoxin)
Less than 0.01 EU per μg by the LAL method / rFC method.
无菌(Sterility)
Negative
支原体(Mycoplasma)
Negative
纯度(Purity)
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景介绍
肿瘤坏死因子受体超家族成员17(TNFRSF17)亦称B细胞成熟蛋白(BCMA)或CD抗原CD269,是肿瘤坏死因子受体超家族成员。该蛋白包含一个TNFR-Cys结构域重复序列,特异性表达于成熟B细胞(不表达于T细胞或单核细胞),是TNFSF13B/BLyS/BAFF和TNFSF13/APRIL的受体。TNFRSF17能促进B细胞存活,参与体液免疫调节,并可激活NF-kappa-B与JNK信号通路。
