This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 74.1 kDa. The protein migrates as 130-150 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Human CD27 Ligand, Fc Tag (active trimer) (MALS verified) on SDS-PAGE under non-reducing (NR) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
The purity of Human CD27 Ligand, Fc Tag (active trimer) (MALS verified) (Cat. No. CDL-H5266) was more than 85% in HP-SEC, and around 160-190 kDa verified by SEC-MALS.
Immobilized Human CD27, His Tag (Cat. No. CD7-H522b) at 2 μg/mL (100 μL/well) can bind Human CD27 Ligand, Fc Tag (active trimer) (MALS verified) (Cat. No. CDL-H5266) with a linear range of 0.2-8 ng/mL (QC tested).
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.
