Biological Activity

Interleukin 1 beta (IL-1β) is a proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. IL-1 alpha and IL-1 beta binds to the same receptor and has similar if not identical biological properties. These cytokines have a broad range of activities including, stimulation of thymocyte proliferation, by inducing IL-2 release, B-cell maturation and proliferation, mitogenic FGF-like activity and the ability to stimulate the release of prostaglandin and collagenase from synovial cells.

Recombinant Human Interleukin-1 Beta expressed the target gene encoding Ala117-Ser269.

Measured by its ability to induce NF-kB signaling in 293-IL1 Res cells, the ED50 for this effect is 20-100 pg/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.
