Human CD27 Ligand, Fc Tag (TN7-H526x) is expressed from human 293 cells (HEK293). It contains AA Gln 39 - Pro 193 (Accession # AAH00725).
Predicted N-terminus: Glu
This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 44.6 kDa. The protein migrates as 50-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>92% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM tris, 100 mM glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

Immobilized Human CD27 Ligand, Fc Tag (Catalog # TN7-H526x) at 10μg/mL (100 μL/well) can bind Biotinylated Human CD27, Fc Tag (Catalog # TN7-H82F6) with a linear range of 4.9-156 ng/mL.
Cluster of Differentiation 70 (CD70) is also known as CD27 ligand (CD27L / CD27LG), TNFSF7, TNFSF7G, is a type II transmembrane glycoprotein belonging to the TNF superfamily (TNFSF) and is a surface antigen found on activated T-and B-lymphocytes and mature dendritic cells. Binding of CD70 to its receptor CD27 induces in priming, effector functions, differentiation and memory formation of T-cells, and thus is invloved in the biological processes including T-cell activation, the proliferation of costimulated T-cells, as well as the generation of cytolytic T-cells. CD70 on T cells provides costimulatory signals that are required for T cell proliferation, clonal expansion and the promotion of effector T cell formation. CD70 on mouse B cell has been shown to inhibit terminal differentiation of activated B cells into plasma cells and enhances commitment to memory B cell responses. CD70 induces proliferation and IFNγ production, on NK cells.
