Biological Activity

Indoleamine 2,3-dioxygenase (IDO) is a heme enzyme that initiates the oxidative degradation of the least abundant, essential amino acid, l-tryptophan, along the kynurenine pathway. IDO activity is associated with immunosuppression and immune attenuation. IDO can contribute to immune escape when expressed directly in tumor cells or when expressed in immunosuppressive antigen presenting cells such as tolerogenic dendritic cells or tumor associated macrophages.

Recombinant Human Indoleamine 2,3-dioxygenase/IDO expressed the target gene encoding Met1-Gly403 with a 6His tag at the N-terminus.

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.
