Recombinant Human TNFSF13, HA-tagged

Cat. No.: TNFSF13-349H
Product Overview: Recombinant Human TNFSF13 (Ala105-Leu250) fused HA tag at N terminal, was expressed in HEK293 Cells.
Description: APRIL 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. Human APRIL shares 85% aa sequence identity with mouse and rat APRIL. Among TNF superfamily ligands, BAFF shows the greatest sequence homology with APRIL, and the two proteins exhibit overlapping biological activities. Both APRIL and BAFF bind and signal through the TNF superfamily receptors TACI and BCMA, and BAFF additionally functions through BAFF R. APRIL can form bioactive heterotrimers with BAFF, and these circulate in the serum of patients with rheumatic immune disorders. A bioactive protein known as TWEPRIL consists of the intracellular domain, transmembrane segment, and stalk region of TWEAK fused to the TNF homology domain of APRIL. TWEPRIL is expressed in monocytes and activated T cells, and in contrast to APRIL, it is presented on the cell surface.

Molecular Mass: The recombinant human TNFSF13 predicts a molecular mass of 21.7 kDa. It migrates as 26 kDa band in SDS-PAGE under reducing conditions.
Predict N-terminal: Tyr
Formulation: Lyophilized from a 0.2 μm filtered solution in Tris-HCl and NaCl with BSA as a carrier protin.
Purity: >95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Activity: Measured in a cell proliferation assay using anti-IgM stimulated mouse B cells.The ED50 for this effect is typically 5-25 ng/mL in the presence of goat anti-mouse IgM.
Endotoxin Level: <1.0 EU per 1 μg of the protein by the LAL method.
Reconstitution: Reconstitute at 100 μg/mL in PBS containing at least 0.1% human or bovine serum albumin.
Storage: 12 months from date of receipt, -20 to -70°C as supplied. 1 month, 2 to 8 °C under sterile conditions after reconstitution. 3 months, -20 to -70°C under sterile conditions after reconstitution. Avoid repeated freeze/thaw cycles.
