Biological Activity

The role of Recombinant Human IL-4 Protein (CHO) in the induction of monocytes into DCs is to inhibit the overgrowth of macrophages, thereby directing monocyte differentiation toward DCs. Also, IL-4 has the ability to reduce cell surface expression of CD14 molecules, an important marker for the differentiation of monocytes into DCs. The combined effect of GM-CSF and IL-4 can lead to targeted differentiation of monocytes into immature DCs, which have a strong capacity for antigen uptake and processing, but a weak capacity for antigen presentation. 

DNA sequence encoding human IL-4 ( GenBank: AAH70123.1 H25-S153 ) expressed with an Fc tag at the C- terminus. 

Measured by the cell proliferation assay with TF-1 cells, the ED50 is ≤0.5 ng/mL. 

Endotoxin <0.1 EU/μg

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.
