Human APRIL/TNFSF13 Antibody Summary

Species Reactivity
Detects human APRIL/TNFSF13 in direct ELISAs. In direct ELISAs, approximately 10% cross-reactivity with recombinant mouse APRIL is observed, and no cross-reactivity with recombinant human BAFF is observed.
Monoclonal Mouse IgG1 Clone # 670820
Protein A or G purified from hybridoma culture supernatant
Human embryonic kidney cell line HEK293-derived recombinant human APRIL/TNFSF13
Accession # O75888
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Measured by its ability to neutralize APRIL/TNFSF13-induced proliferation in mouse B cells. The Neutralization Dose (ND50) is typically 0.15-0.75 ug/mL in the presence of 200 ng/mL Recombinant Human APRIL/TNFSF13.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Cell Proliferation Induced by APRIL/TNFSF13 and Neutralization by Human APRIL/TNFSF13 Antibody. Recombinant Human APRIL/TNFSF13 induces proliferation in mouse B cells in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human APRIL/TNFSF13 (200 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human APRIL/TNFSF13 Monoclonal Antibody (Catalog # MAB5860). The ND50 is typically 0.15-0.75 µg/mL.

Background: APRIL/TNFSF13

APRIL (a proliferation inducing ligand), also known as TNFSF13, TALL2, and TRDL1, is a member of the TNF ligand superfamily. It is synthesized as a 32 kDa type II transmembrane protein which is cleaved by furin in the Golgi to release a 17 kDa soluble molecule. Secreted APRIL consists almost entirely of a single TNF homology domain. Little or no transmembrane APRIL is expressed on the cell surface. Alternate splicing generates isoforms with short deletions at the N- or C‑terminus. Both APRIL and the closely related protein BAFF signal through the TNF superfamily receptors TACI and BCMA to promote cellular proliferation and protect from apoptosis. APRIL can form bioactive heterotrimers with BAFF. A bioactive cell surface-expressed protein known as TWEPRIL consists of the intracellular domain, transmembrane segment, and stalk region of TWEAK fused to the TNF homology domain of APRIL. Human APRIL shares 85% amino acid sequence identity with mouse and rat APRIL.
