Background Information


Human CD112, also known as nectin-2 or poliovirus receptor-related protein 2 (PVRL2), is a cell adhesion molecule belonging to the immunoglobulin superfamily. It is broadly expressed on epithelial cells, endothelial cells, and antigen-presenting cells. CD112 plays a dual role in maintaining cell–cell adhesion and regulating immune responses, particularly in interactions between immune cells and target tissues.

Structurally, CD112 is a type I transmembrane glycoprotein composed of three extracellular immunoglobulin-like domains (one V-type followed by two C2-type domains), a single transmembrane region, and a short cytoplasmic tail. This structure enables it to participate in both homophilic (CD112–CD112) and heterophilic interactions with other nectin family members.

Functionally, CD112 serves as a ligand for several immune receptors, most notably CD226 (DNAM-1), TIGIT, and CD112R (PVRIG). Binding to CD226 provides co-stimulatory signals that enhance T cell and natural killer (NK) cell activation, while interactions with TIGIT and CD112R deliver inhibitory signals that dampen immune responses. Thus, CD112 is part of a regulatory axis balancing immune activation and inhibition.

In disease, CD112 is frequently upregulated in various cancers, where it contributes to immune evasion by preferentially engaging inhibitory receptors such as TIGIT and CD112R on T cells and NK cells. This suppresses anti-tumor immunity and supports tumor progression.

Therapeutically, CD112 is an emerging target in cancer immunotherapy. Strategies include blocking inhibitory pathways (e.g., TIGIT or CD112R antibodies) or enhancing CD226-mediated activation. These approaches aim to restore immune function and improve anti-tumor responses, often in combination with other checkpoint inhibitors.

Frequently Asked Questions


How do I determine the optimal antibody concentration/titer for my experiment?
We recommend titrating each new antibody lot on your own cell type and instrument, since optimal concentration depends on cell density, target expression level, and cytometer sensitivity. Suggested starting dilutions or test sizes (e.g., µg or µl per 10^6 cells) are provided on the product page as a starting reference point, not a fixed requirement.

Can these antibodies be used for intracellular or intranuclear staining, or only surface staining?
Intended use (surface, intracellular, or both) is specified per product, indicated under Application. The appropriate Related Protocol is linked for each product. If you need to detect both surface and intracellular markers in the same panel, confirm each antibody's compatibility with your fixation/permeabilization protocol before combining them.

What controls should I use alongside these antibodies?
Matched isotype controls (same host species, isotype, and conjugate) are available for most clones to help distinguish specific binding from background/non-specific staining and are linked on each product page. Unstained, single-color compensation, and fluorescence-minus-one (FMO) controls are also recommended, especially for multicolor panel design.

Can I combine InnoCyto Flow Cytometry antibodies into a multicolor panel?
Yes — antibodies across our catalog are designed to be panel-compatible, and conjugate options are offered specifically to support multiplexing. When building a panel, pair bright fluorophores with low-expression targets, avoid excessive spectral overlap, and confirm compensation is set up correctly for your specific fluorochrome combination. Use our Panel Builder to simplify the process.
