IMP-1536

TNFSF8

Recombinant extracellular domain (Gln 63-Asp 234) of human CD30 Ligand (NP_001235.1) was fused with the Fc region of human IgG1 at the N-terminus.

CD30 ligand (CD30L), also known as CD153 and TNFSF8, is a membrane-associated glycoprotein belonging to the TNF superfamily and TNFR superfamily, and is a specific ligand for CD30/TNFRSF8 originally described as a cell surface antigen and a marker for Hodgkin lymphoma and related hematologic malignancies. CD30L is a type-II membrane glycoprotein expressed on activated T cells, stimulated monocyte-macrophages, granulocytes, eosinophils, and some Burkitt-like lymphoma cell lines. CD30L is capable of transducing signals through CD30 on different CD30+ lymphoma cell lines, and mediates pleiotropic biologic effects including cell proliferation, activation, differentiation, as well as cell death by apoptosis. CD30-CD30 ligand interaction has been suggested to have a pathophysiologic role in malignant lymphomas, particularly Hodgkin disease, large cell anaplastic lymphomas and Burkitt lymphomas, and is also involved in activation and functioning of the T cell-dependent immune response. Thus, CD153 and its receptor CD30 are regarded as therapeutic targets in hematologic malignancies, autoimmune and inflammatory diseases.

Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5% mannitol and 0.01% Tween80.

The recombinant human Fc/CD30L is a disulfide-linked homodimeric protein. The reduced monomer consists of 429 amino acids and has a predicted molecular mass of 47.8 kDa. As a result of glycosylation, the apparent molecular mass of rh Fc/CD30L monomer is approximately 60-65 kDa in SDS-PAGE under reducing conditions.

Samples are stable for up to twelve months from date of receipt at -20 to -80 centigrade.
Store it under sterile conditions at -20 to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

Measured by its binding ability in a functional ELISA. Immobilized human CD30L-hFc at 2 μg/mL (100 μL/well) can bind human CD30/TNFRSF8-Fch, the EC50 of human CD30/TNFRSF8-Fch is 15-60 ng/mL.
