Expression system: E. coli
Purity: SDS-PAGE analysis, > 95%, HIGH performance liquid chromatography analysis, > 95%
Endotoxin: protein < 0.2 EU/μg was determined by gel coagulation
Apparent molecular weight: ~19.5 kDa, sdS-PAGE under reduction conditions
Storage and stability: After receiving, the product remains stable at temperatures below -70°C for up to 6 months. After recombination, the product should be stable at 4°C for 1 week or -20°C for 3 months. For long-term preservation, carrier protein (e.g. 0.1% BSA) is recommended. Avoid repeated freeze-thaw cycles.
Bioactivity: ED50 < 0.5µg/ mL, niH-3T3 cells were used for cell proliferation assay in the presence of mouse Klotho 1.25µg/ mL and heparin 10µg/ mL, corresponding specific activity > 2.0 × 103 units /mg. Along with FGF-19/15 and FGF-23, FGF-21 is classified as a member of the atypical FGF-subfamily because it must bind to the Klotho coreceptor in order to bind to the FGF-receptor and activate downstream signaling pathways. In vivo, FGF-21 is expressed in liver, pancreas, adipose tissue and skeletal muscle and plays a central role in energy metabolism. Fgf-21 expression is stimulated by free fatty acids and insulin resistance status, and is associated with systemic insulin resistance. Fgf-21 activates glucose uptake by fat cells and increases insulin sensitivity, suggesting that it is a new target with potential anti-diabetic properties.

| 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. |
