CD70, a type II transmembrane glycoprotein of the TNF family with cytokine activity, is the ligand for the CD27 receptor1. Mouse CD70 (mCD70) has a potent co-stimulatory effect on T cell proliferation1 and acts as an immune-checkpoint2. In mouse, but not in humans, the CD70-CD27 axis mediates a negative feedback system that enables the immune system to modulate hematopoiesis2. Additionally, CD70-CD27 interactions are important to the formation of memory and plasma B cells. Immunotherapies that aim to eradicate tumor cells by targeting CD70 overexpression are being developed2. FR70 inhibits mCD70 binding to mCD27-Ig, a recombinant soluble form of mCD271, as well as to mCD27 in vitro3, 4 and in vivo5.
FR70 was produced by immunizing an F344/DuCrj rat with A20 cells and fusing the splenocytes with P3U1 cells to create hybridoma lines1. HAT selection was performed, and FR70 was identified by its strong reactivity against mCD70-BHK21 cells.

Blocking with FR70 can prolong graft acceptance6, 7. When mouse cardiac allogenic graft recipients are treated with FR70, tolerogenic dendritic cells and T regulatory cells are induced, resulting in decreased cytotoxic T lymphocyte proliferation as well as long-term graft acceptance6. Blocking with FR70 also prolongs mouse corneal graft survival7.

This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.
