Recombinant Mouse BAFF (TNFSF13B/TNFSF20) belongs to the tumor necrosis factor family. TNFSF13/APRIL binds to the same 2 receptors. Together, they form a 2 ligands -2 receptors pathway involved in the stimulation of B- and T-cell function and the regulation of humoral immunity. The target gene encoding Ala127-Leu309 is expressed with a mFc tag at the N-terminus. A third B-cell specific BAFF-receptor (BAFFR/BR3) promotes the survival of mature B-cells and the B-cell response. Isoform 2 seems to inhibit isoform 1 secretion and bioactivity. Isoform 3 acts as a transcription factor for its own parent gene, in association with NF-kappa-B p50 subunit, at least in autoimmune and proliferative B-cell diseases. The presence of Delta4BAFF is essential for soluble BAFF release by IFNG/IFN-gamma-stimulated monocytes and for B-cell survival. It can directly or indirectly regulate the differential expression of a large number of genes involved in the innate immune response and the regulation of apoptosis.

| Recombinant Human HGF (CHO-expressed)
Recombinant human Hepatocyte Growth Factor (rhHGF) , also known as hepatopoietin-A and scatter factor, is a pleiotropic mitogen belonging to the peptidase S1 family (plasminogen subfamily). It is produced by mesenchymal cells and acts on epithelial cells, endothelial cells and haemopoietic progenitor cells. |
| Recombinant Human RIPK3 Protein (E. coli, N-His)
RIPK3 is a kinase that controls necroptosis and apoptosis. In necroptosis, activated by TNF-α and ZBP1, RIPK3 phosphorylates MLKL, leading to membrane damage. Necroptosis is dependent on receptor-interacting protein kinase 3 (RIPK3), a protein shown to play an important role in experimental models of critical illness. RIPK3 promotes kidney tubular injury via mitochondrial dysfunction. The FAO-dependent RIPK3 mediates pathogenesis of acute lung injury. |
| Recombinant Influenza B Hemagglutinin/HA Protein (HEK293, C-His)
Recombinant Influenza B Hemagglutinin / HA Protein is a homotrimer that recognizes target cells in vertebrates and does so by binding to salivary acid-containing receptors on these cells. When it binds to the target cell, it causes the host inner membrane to fuse with the viral membrane, thereby facilitating the entry of the viral genome into the target cell. |
| Recombinant Human FGF-9 (E. coli)
Fibroblast Growth Factor-9 (FGF-9) is a heparin binding growth factor that belongs to the fibroblast growth factor (FGF) family. ED50 < 2.0 ng/ mL, determined by 3T3 cell proliferation assay, corresponding to > 5.0× 105 units/mg. |
| Recombinant Human CXCL13/BCA-1 (E. coli)
CXCL13, also known as B-lymphocyte chemoattractant (BLC), is a CXC chemokine that is constitutively expressed in secondary lymphoid organs. Recombinant human CXCL13 is a single non-glycosylated polypeptide chain containing 87 amino acids and mature human BCA-1 shares 64 % amino acid sequence similarity with the murine protein and 23–34 % amino acid sequence identity with other known CXC chemokines. Determined by a chemotaxis bioassay using human B cells, the biological activity is in a concentration range of 1.0-10 ng/ml. |
