Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
Measured by its ability to neutralize CD30 Ligand/TNFSF8-induced IL‑6 secretion in the HDLM human Hodgkin’s lymphoma cell line. The Neutralization Dose (ND50) is typically 1-4 µg/mL in the presence of 1 µg/mL Recombinant Human CD30 Ligand/TNFSF8 and 10 µg/mL of a cross-linking antibody, Mouse polyHistidine Monoclonal Antibody.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Detection of CD30 Ligand/TNFSF8 in Human PBMCs by Flow Cytometry.
Human peripheral blood mononuclear cells (PBMCs) treated with 50 ng/mL PMA and 200 ng/mL Calcium Ionomycin overnight were stained with Mouse Anti-Human CD3 epsilon APC‑conjugated Monoclonal Antibody (Catalog # FAB100A) and either (A) Mouse Anti-Human CD30 Ligand/TNFSF8 Monoclonal Antibody (Catalog # MAB1028) or (B) Mouse IgG2B Isotype Control (Catalog # MAB004) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B).

IL‑6 Secretion Induced by CD30 Ligand/TNFSF8 and Neutralization by Human CD30 Ligand/TNFSF8 Antibody.
In the presence of a cross-linking antibody, Mouse polyHistidine Monoclonal Antibody (10 µg/mL, Catalog # MAB050), Recombinant Human CD30 Ligand/TNFSF8 (Catalog # 1028-CL) stimulates IL‑6 secretion in the HDLM human Hodgkin’s lymphoma cell line in a dose-dependent manner (orange line), as measured by the Human IL‑6 Quantikine ELISA Kit (Catalog # D6050). Under these conditions, IL‑6 secretion elicited by Recombinant Human CD30 Ligand/TNFSF8 (1 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CD30 Ligand/TNFSF8 Monoclonal Antibody (Catalog # MAB1028). The ND50 is typically 1-4 µg/mL.

Background: CD30 Ligand/TNFSF8
CD30 ligand (CD30L)/TNFSF8 is a type II membrane protein belonging to the TNF superfamily. CD30L is expressed on the cell surface of activated T cells, B cells, and monocytes. The protein is also constitutively expressed on granulocytes and medullary thymic epithelial cells. The specific receptor for CD30L is CD30/TNFRSF8, a type I transmembrane glycoprotein belonging to the TNF receptor superfamily. CD30 was originally identified as a cell surface antigen of Hodgkin's and Reed-Sternberg cells using the monoclonal antibody Ki-1. CD30 is also expressed on different non-Hodgkin's lymphomas, virus-infected T and B cells, and on normal T and B cells after activation. Among T cells, CD30 is preferentially expressed on a subset of T cells producing Th2-type cytokines and on CD4+/CD8+ thymocytes that coexpress CD45RO and IL-4 receptor. CD30 ligation by CD30L mediates pleiotropic effects including cell proliferation, activation, differentiation and cell death by apoptosis. CD30 can act as a costimulatory molecule in thymic negative selection and may also play a critical role in the pathophysiology of Hodgkin's disease and other CD30+ lymphomas. Human and mouse CD30 ligand cDNAs share 70% sequence homology.
