Formulation, Preparation, and Storage

Carrier Free
What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Carrier: 732-CL

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.

FAQs for Recombinant Mouse CD30 Ligand/TNFSF8 Protein

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.
