Description
This gene encodes a member of the PVR (poliovirus receptor) family of immunoglobin proteins. The product of this gene is expressed on several classes of T cells including follicular B helper T cells (TFH). The protein has been shown to bind PVR with high affinity; this binding is thought to assist interactions between TFH and dendritic cells to regulate T cell dependent B cell responses.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human CD155/PVR is coated at 2.5 μg/mL (100 μL/well), the concentration of Recombinant Human TIGIT (T103) Fc Chimera that produces 50% optimal binding response is typically 8-48 ng/mL.
