Human BAFFR / TNFRSF13C, Fc Tag (BAR-H5257) is expressed from human 293 cells (HEK293). It contains AA Ser 7 - Ala 71 (Accession # Q96RJ3-1).
Predicted N-terminus: Ser 7
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 33.2 kDa. The protein migrates as 40-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
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 50 mM Tris,100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

Immobilized Human BAFF, His Tag (Catalog # BAF-H5248) at 5 μg/mL (100 μL/well) can bind Human BAFFR, Fc Tag (Catalog # BAR-H5257) with a linear range of 2-31 ng/mL.
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.
