Stromal cell-derived factor-1 α / CXCL12 (SDF-1α) and SDF-1β, members of the α subfamily of chemokines lacking the ELR domain, were originally identified from mouse bone marrow stromal cell lines using a signal-sequence trap cloning strategy.
The biological activity determined by a chemotaxis bioassay using PHA and rHuIL-2 activated human peripheral blood T-lymphocytes is in a concentration range of 20.0-80.0 ng/ml.

| 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. |
