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 35.1 kDa. As a result of glycosylation, the protein migrates as 45-60 kDa under reducing (R) condition, and 90-116 kDa under non-reducing (NR) condition (SDS-PAGE).
标记(Biotinylation)
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(Biotin:Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
纯度(Purity)
>95% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)
Biotinylated Mouse BAFFR, Fc,Avitag on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
活性(Bioactivity)-ELISA
Immobilized Mouse BAFF, Mouse IgG2a Fc Tag, low endotoxin (Cat. No. BAF-M5257) at 5 μg/mL (100 μL/well) can bind Biotinylated Mouse BAFFR, Fc,Avitag (Cat. No. BAR-M82F0) with a linear range of 0.8-13 ng/mL (QC tested).
Protocol
背景(Background)
BAFF receptor (B-cell activating factor receptor, BAFF-R), also known as tumor necrosis factor receptor superfamily member 13C (TNFRSF13C), is a membrane protein of the TNF receptor superfamily which recognizes BAFF. B-cell activating factor (BAFF) enhances B-cell survival in vitro and is a regulator of the peripheral B-cell population. Overexpression of BAFF in mice results in mature B-cell hyperplasia and symptoms of systemic lupus erythematosus (SLE). Also, some SLE patients have increased levels of BAFF in serum. Therefore, it has been proposed that abnormally high levels of BAFF may contribute to the pathogenesis of autoimmune diseases by enhancing the survival of autoreactive B cells.
