Product Specifications
Immunogen
This antibody was produced by injecting Armenian hamsters intraperitoneally with a mixture of two murine CD27/TNFRSF7 tag-expressing Armenian hamster fibroblast clones (AR0524 and AR0530) in Freund's adjuvant
Specificity
This antibody is specific for mouse CD27/TNFRSF7, which, as in the human system, is largely restricted to cells of the T cell lineage, and is expressed on the great majority of both alpha-beta and gamma-delta T lymphocytes, and thymocytes.

IgG Kappa
Applications for CD27/TNFRSF7 Antibody (LG.3A10) - Azide and BSA Free
Application
Recommended Usage
Flow Cytometry
Optimal dilutions of this antibody should be experimentally determined.
Functional
Optimal dilutions of this antibody should be experimentally determined.
Immunocytochemistry/ Immunofluorescence
Optimal dilutions of this antibody should be experimentally determined.
Immunoprecipitation
Optimal dilutions of this antibody should be experimentally determined.
Application Notes
This antibody is specific for murine CD27, and has been used to assess the distribution of CD27 expression using IF, FC and IP analysis (Gravstein, 1995). Upon cross-linking, this antibody has been shown to induce a 4-fold increase in T cell proliferation in response to suboptimal stimulation with concanavalin A (Gravestein, 1995), indicating that this antibody is able to mimic ligand binding.

Background: CD27/TNFRSF7
Membrane-bound CD27 is expressed as a disulfide-linked homodimer (3). CD27 binds to the ligand CD70, a transmembrane glycoprotein that is transiently expressed on activated immune cells such as antigen presenting cells (APCs), dendritic cells (DCs), NK cells, B cells, and T cells (1,2,6,7). The receptor-ligand binding interaction leads to NFkappaB and c-Jun pathway activation which promotes immune stimulation and activation and survival of CD4+ T cells, CD8+ T cells, memory T cells, and NK cells (2,6,7). Both CD27 and CD70 are often abnormally expressed or dysregulated on malignant and cancer cells leading to immune evasion and tumor progression (7). CD27 has become a target of interest of immunotherapies for viral infections, autoimmune disease, and cancer (2). Varlilumab, an agonistic CD27 monoclonal antibody (mAB), has entered clinical trials for the treatment of hematological and solid tumor cancers (1,6). Additional clinical trials are in process that combine varlilumab with other immune checkpoint inhibitors like the programmed cell death protein-1 (PD-1) blocking mAb nivolumab (1,2). Initial results are promising, suggesting that targeting CD27, especially in combination with other therapeutics, may be a promising and effective immunotherapy for a variety of pathologies (1,2,6).
