APRIL & BAFF

Source

Human APRIL & BAFF Protein, His Tag (APB-H5243) is expressed from human 293 cells (HEK293). It contains AA Ala 105 - Leu 250 (APRIL) & Gln 68-Arg 133 (BAFF) (Accession # Q9Y275-1 (APRIL) & O75888-1 (BAFF)).

Predicted N-terminus: His

Molecular Characterization

This protein carries a polyhistidine tag at the N-terminus. The protein has a calculated MW of 50.7 kDa. The protein migrates as 53-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation. The protein is a heterotrimer consisting of one APRIL and two BAFF.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 150 mM NaCl, pH8.0 with trehalose as protectant.

Background

BAFF and APRIL are two members of the TNF superfamily that are secreted by activated myeloid cells and have costimulatory activity on B cells. BAFF/APRIL signaling regulates a diverse range of biological processes, including cell differentiation, proliferation, survival, and effector functions. Dysregulation of the BAFF/APRIL system has been linked to several inflammatory conditions, specifically autoimmune diseases. Elevated levels of BAFF and APRIL have been reported in autoimmune SLE patients. Both BAFF and APRIL have been described as homotrimeric molecules, a feature common to members of the TNF superfamily. But APRIL and BAFF can form active heterotrimer molecules when co-expressed, and circulating heterotrimer exists in serum samples of patients with systemic immune rheumatic diseases. These findings increase the possibility that the active BAFF/APRIL heterotrimer may play a role in rheumatic diseases and other autoimmune diseases.
