HSP70 can serve a cytokine function to initiate both innate and adaptive immunity through activation of APC. HSP serves also a chaperone function and facilitates the presentation of antigen peptide to T cells. The well-conserved Hsp70 chaperones are ATP dependent: binding and hydrolysis of ATP regulate their interactions with unfolded polypeptide substrates, and ATPase cycling is necessary for their function. All cellular functions of Hsp70 chaperones use the same mechanism of ATP-driven polypeptide binding and release.
The recombinant human HSP70 (HSPA1A) consists of 651 amino acids and predicts a molecular mass of 71.4 kDa. A DNA sequence encoding the human HSPA1A (Ala2-Asp641) was expressed with a polyhistidine tag at the N-terminus.

| 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. |
