Data Examples
Detection of Human and Mouse PVRIG by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line, MOLT‑4 human acute lymphoblastic leukemia cell line, Daudi human Burkitt's lymphoma cell line, Raji human Burkitt's lymphoma cell line, CEM human T-lymphoblastoid cell line, and TK‑1 mouse T cell lymphoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human/Mouse PVRIG Monoclonal Antibody (Catalog # MAB9365) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for PVRIG at approximately 36 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Immunocytochemistry
PVRIG in MOLT‑4 Human Cell Line. PVRIG was detected in immersion fixed MOLT‑4 human acute lymphoblastic leukemia cell line using Mouse Anti-Human/Mouse PVRIG Monoclonal Antibody (Catalog # MAB9365) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: PVRIG
Human PVRIG (poliovirus receptor related immunoglobulin domain-containing protein), also known as CD112 receptor (CD112R), is an approximately 34 kDa single transmembrane protein in the poliovirus receptor-like protein (PVR) family (1). It is composed of a single extracellular IgV domain, one transmembrane domain, and a long intracellular domain. The intracellular domain contains two tyrosine residues, one within an ITIM-like motif that is a potential docking site for phosphatases (1). The extracellular domain sequence of human and mouse PVRIG have approximately 65% similarity. The human PVRIG gene is preferentially expressed in lymphocytes, such as T cells and NK cells, but not in monocyte derived dendritic cells (1). PVRIG functions as a cell surface receptor for Nectin-2/CD112, a cell surface protein that is widely expressed on antigen-presenting cells and tumor cells. Disrupting the PVRIG/Nectin-2 interaction enhances human T cell response, suggesting PVRIG is a novel checkpoint for human T cells (1).
