Nectin-2/CD112 蛋白, Human (HEK293)

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 (HEK293) is the recombinant human-derived Nectin-2/CD112 protein, expressed by HEK293 , with tag free. The total length of Nectin-2/CD112 Protein, Human (HEK293) is 329 a.a., with molecular weight of 45-55 kDa.

Nectin-2/CD112 是一种 T 细胞信号传导的多功能调节剂，根据其所结合的受体，具有共刺激剂或共抑制剂的双重作用。与 CD226 结合可促进 T 细胞增殖和细胞因子产生，包括 IL2、IL5、IL10、IL13 和 IFNG 等关键因子。相比之下，与 PVRIG 的相互作用会抑制 T 细胞增殖，并且这些相互作用本质上是竞争性的。此外，如先前的研究所示，Nectin-2/CD112 可能是一种细胞粘附蛋白。此外，在微生物感染的情况下，它充当单纯疱疹病毒 1 (HHV-1) 突变体 Rid1、单纯疱疹病毒 1 (HHV-2) 和伪狂犬病病毒 (PRV) 的受体。

1.Measured by its binding ability in a functional ELISA. Immobilized Human CD112 at 0.5 μg/mL (100 μL/well) can bind Biotinylated Human DNAM-1. The ED₅₀ for this effect is 0.6317 μg/mL, corresponding to a specific activity is 1.58×10³ Unit/mg.
2.Immobilized Human Nectin-2, No Tag at 1 μg/mL (100 μl/well) on the plate. Dose response curve for Human PVRIG, mFc Tag with the ECsub>50 of ≤0.19 μg/mL determined by ELISA.

无菌粉末

Lyophilized from a 0.2 μm filtered solution of 100 mM Glycine, 10 mM NaCl, 50 mM Tris, pH 7.5 or 50 mM Tris, 10 mM NaCl, pH 7.5 or PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

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.
