Expression system: E. coli
Purity: SDS-PAGE Analysis > 95%
Theoretical molecular weight: 13500 Da
Storage and stability: the powder can be stored for several weeks at 4 ° C. For long-term storage, please store it at -20 ° C.
Biological activity: >15 u/mg protein, 1 u is defined as the amount of 1 microgram of protein bound. Streptavidin can bind to four moles of biotin per mole of protein and shows a very high affinity, about 10000-15000 da. Streptavidin lacks the carbohydrate side chain on the avidin, and its isoelectric point is 6.5 to 10, which is far closer to the point where the most useful biological interaction occurs. Therefore, streptavidin usually exhibits much lower nonspecific binding than avidin.

| 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. |
