Biotinylated Mouse BAFFR, Fc,Avitag (BAR-M82F0) is expressed from human 293 cells (HEK293). It contains AA Ser 10 - Ala 71 (Accession # NP_082351).
Predicted N-terminus: Ser 10
This protein carries a human IgG1 Fc tag at the C-terminus, followed by a 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).
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Biotinylated Mouse BAFFR, Fc,Avitag on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
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).
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.
