ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Clone SKII.4 is ZooMAb^® mouse recombinant monoclonal antibody that specifically detects Poliovirus receptor (PVR/CD155). It targets an epitope within the extracellular domain.

SK-N-S1 human neuroblastoma cells.

Poliovirus receptor (UniProt: P15151; also known as Nectin-like protein 5, NECL-5, CD155) is encoded by the PVR (also known as PVS) gene (Gene ID: 5817) in human. CD155 is a single-pass type I, N-glycosylated, membrane protein that mediates NK cell adhesion and triggers NK cell effector functions. It is ubiquitously expressed, and many human tumors are reported to significantly upregulate its expression. It binds two different NK cell receptors: CD96 and CD226 and these interactions accumulate at the cell-cell contact site, leading to the formation of a mature immunological synapse between NK cell and the target cell. This may trigger adhesion and secretion of lytic granules and IFN-γ and activate cytotoxicity of activated NK cells. CD155 serves as a receptor for poliovirus and may play a role in axonal transport of poliovirus by targeting virion-PVR-containing endocytic vesicles to the microtubular network through interaction with dynein light chain Tctex-type 1 (DYNLT1). It is synthesized with a signal peptide (aa 1-20), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 21-343), a transmembrane domain (aa 344-367), and a cytoplasmic domain (aa 368-417). It contains two Ig-like C2 type domains (aa 145-237 and 233-328), and an Ig-like V-type domain that is shown to be necessary and sufficient for virus binding and uptake. CD155 also has one the immunoreceptor tyrosine-based inhibitor motif (ITIM; aa 396-401) that when phosphorylated by Src kinases binds to the SH2 domain of several SH2-containing phosphatases. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.

Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
