Applications

Recommended Concentration
Sample
Western Blot
1 µg/mL
Recombinant Human CD27/TNFRSF7 Fc Chimera (Catalog # 382-CD)
Flow Cytometry
2.5 µg/106 cells
Human whole blood lymphocytes
CyTOF-ready
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
 
Neutralization
Measured by its ability to neutralize CD27/TNFRSF7-induced inhibition of proliferation in mouse splenic T cells. The Neutralization Dose (ND50) is typically 0.2-0.4 µg/mL in the presence of 3 µg/mL Recombinant Human CD27/TNFRSF7 Fc Chimera, 10 µg/mL Recombinant Mouse CD27 Ligand/TNFSF7, and sub-optimal amounts of Mouse CD3 epsilon Monoclonal Antibody.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

CD27/TNFRSF7 Inhibition of CD27 Ligand/TNFSF7-dependent Cell Proliferation and Neutralization by Human CD27/TNFRSF7 Antibody. In the presence of sub-optimal amounts of Mouse CD3 epsilon Monoclonal Anti­body (Catalog # MAB484) and Recombinant Mouse CD27 Ligand (10 µg/mL, Catalog # 783-CL), Recombinant Human CD27 Fc Chimera (Catalog # 382-CD) inhibits proliferation in mouse splenic T cells in a dose-dependent manner (orange line). Under these conditions, inhibition of proliferation elicited by Recombinant Human CD27 Fc Chimera (3 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CD27 Monoclonal Antibody (Catalog # MAB382). The ND50 is typically 0.2‑0.4 µg/mL.

Background: CD27/TNFRSF7

Human CD27 is a lymphocyte-specific member of the TNF receptor superfamily. CD27 is expressed on a subset of human thymocytes and on the majority of mature T cells. CD27 expression is up-regulated after TCR stimulation. Within the CD4+ compartment, it is preferentially expressed on CD45RA+ cells. In contrast, it is preferentially expressed on CD45RO+ cells in the CD8+ compartment. CD27 also appears to be a potential marker for memory B cells. It exists as both a disulfide‑linked dimer on the cell surface and as a soluble protein found in serum. Human CD27 is a 260 amino acid (aa) protein with a 20 aa signal, a 173 aa extracellular domain, a 20 aa transmembrane domain, and a 47 aa cytoplasmic domain. The ligand for CD27 is CD70. CD70 is expressed on thymic stromal cells and a small subset of activated T cells. Additionally a subset of activated B cells express CD70. The CD27/CD70 interaction appears to be a weak costimulatory pathway involved in T cell and B cell immune response. CD27/CD70 interactions may be more involved in controlling the expansion phase of an immune response. This would be in contrast to B7/CD28 interactions, which are important for the activation phase of immune responses.
