Active Recombinant Human TNFRSF7/CD27 Protein

CD27

Thr21-Ile192

CD27, also known as TNFRSF7, is a member of the TNF-receptor superfamily limited to cells of the lymphoid lineage, and exists as both a dimeric glycoprotein on the cell surface and as a soluble protein in serum. As a type I transmembrane glycoprotein of about 55 kDa existing as disulfide-linked homodimer, CD27 has been shown to play roles in lymphoid proliferation, differentiation, and apoptosis.It has an important role in the generation of T cell immunity and is an robust marker for normal memory B cells. It is a T and B cell co-stimulatory molecule, the activity of CD27 is governed by its TNF-like ligand CD70 on lymphocytes and dendritic cells. The CD27-CD70 interaction is required for Th1 generation responses to differentiation signals and long-term maintenance of T cell immunity, and meanwhile, plays a key role in regulating B-cell differentiation, activation and immunoglobulin synthesis.

Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

Measured by its binding ability in a functional ELISA. Immobilized Human CD27 at 2 μg/mL (100 μL/well) can bind Human CD70 with a linear range of 0.781-0.885 ng/mL.
