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 co-express 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 co-stimulatory 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.

FAQs for Recombinant Human CD30 Ligand/TNFSF8 Protein, CF

Showing  1 - 1 of 1 FAQ Showing All
  • Q: This protein datasheet indicates I need to use a cross-linking antibody, Catalog # MAB050, for biological activity. What is this antibody and is it really necessary?

    A: The antibody is directed against a 6x histidine repeat and is recommended for use as a cross-linker of proteins with 6x his-tag. Crosslinking is often used for proteins that require receptor trimerization and can result greater biological activity. R&D Systems Quality Control tests the performance of these proteins in the presence of the cross-linking antibody. Therefore, it is necessary to use this antibody when trying to achieve the same level of specific activity described in the datasheet.
