APRIL (mouse) (multimeric) (rec.)

Product description: Protein. The extracellular domain of mouse APRIL (aa 88-232) is fused at the N-terminus to mouse ACRP30headless (aa 18-110) and a FLAG®-tag. Source: HEK 293 cells. Endotoxin content: <0.02EU/µg purified protein (LAL test; Lonza). Lyophilized. Contains PBS + 0.5% Trehalose. Binds to human and mouse BCMA and TACI. Binds to proteoglycans. Purity: >95% (SDS-PAGE). APRIL is a cytokine that belongs to the TNF superfamily and binds to TACI and BCMA. It is implicated in the regulation of tumor cell growth, is involved in monocyte/macrophage-mediated immunological processes and functions as an important survival factor for plasmablasts and bone marrow plasma cells. MultimericAPRIL™ is a high activity construct in which two trimeric APRIL ligands are artificially linked via the collagen domain of ACRP30. This construct very effectively stimulates proliferation B cell. A basic amino acid sequence (QKQKKQ) close to the N-terminus of APRIL is required for binding to negatively charged sulfated glycosaminoglycan side chains of proteoglycans. Proteoglycans mediate binding of APRIL to tumor cells as well as primary lymphoid cells.
