Nectin-2/CD112 Protein, Human (329a.a, HEK293, Fc)

Nectin-2/CD112 protein has dual roles in T-cell signaling: as a costimulator with CD226, promoting proliferation and cytokine production, and as a coinhibitor with PVRIG, inhibiting proliferation. It also acts as a cell adhesion protein and a receptor for certain viruses. Nectin-2/CD112 Protein, Human (329a.a, HEK293, Fc) is the recombinant human-derived Nectin-2/CD112 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of Nectin-2/CD112 Protein, Human (329a.a, HEK293, Fc) is 329 a.a., with molecular weight of 70-80 kDa.

Nectin-2/CD112, a versatile modulator of T-cell signaling, exhibits dual roles as a costimulator or coinhibitor, contingent upon the receptor it engages. Binding to CD226 prompts the stimulation of T-cell proliferation and cytokine production, including key players like IL2, IL5, IL10, IL13, and IFNG. In contrast, interaction with PVRIG results in the inhibition of T-cell proliferation, and these engagements are competitive in nature. Additionally, Nectin-2/CD112 serves as a probable cell adhesion protein, as indicated in previous studies. Furthermore, in the context of microbial infection, it acts as a receptor for herpes simplex virus 1 (HHV-1) mutant Rid1, herpes simplex virus 1 (HHV-2), and pseudorabies virus (PRV).

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 5% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
