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.

Biological activity: Interferon β (IFN-β) acts via STAT1 and STAT2 and is known to up-regulate and down-regulate a variety of genes, most of which are involved in antiviral immune responses. It is a member of type I interferon, which includes IFN-α, -β, τ and -ω. IFN-β plays an important role in inducing nonspecific resistance to a wide range of viral infections. It also affects cell proliferation and modulates immune responses.

Recombinant Human GDF-15 Protein (HEK293 N-hFc)

Growth-differentiation factor 15 (GDF15), also known as MIC-1, is a secreted member of the transforming growth factor (TGF)-β superfamily. GDF-15 has a role in regulating inflammatory and apoptotic pathways in injured tissues and during disease processes. GDF-15 overexpression arising from an expanded erythroid compartment contributes to iron overload in thalassemia syndromes by inhibiting hepcidin expression.

Recombinant Human FGFR1 Protein (HEK293, C-His)

FGFR1, also known as CD331, is a full-length representative protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain.

Recombinant Human FGFR2 Protein (HEK293, C-His)

FGFR2, also known as CD332, acts as cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of cell proliferation, differentiation, migration and apoptosis, and in the regulation of embryonic development. FGFR2 plays an essential role in the regulation of osteoblast differentiation, proliferation and apoptosis, and is required for normal skeleton development. It also promotes cell proliferation in keratinocytes and imature osteoblasts, but promotes apoptosis in differentiated osteoblasts.

Recombinant Mouse BMP-4 Protein (E. coli, C-His)

Bone Morphogenetic Protein-4 (BMP-4) is a critical signaling molecule required for the early differentiation of the embryo and establishing of a dorsal-ventral axis. BMP-4 is secreted from the dorsal portion of the notochord, and it acts in concert with sonic hedgehog to establish a dorsal-ventral axis for the differentiation of later structures.

Recombinant Human Coagulation Factor X (HEK293, C-Fc)

Coagulation factor X, belongs to the peptidase S1 family. Coagulation factor X is initially synthesized in the liver. Coagulation factor X is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting.
