研究方向
TRAILR4/TNFRSF10D 蛋白作为细胞毒性配体 TRAIL 的受体发挥作用，尽管它包含截短的死亡结构域，使其无法诱导细胞凋亡。矛盾的是，TRAILR4/TNFRSF10D 不仅不能诱导细胞凋亡，而且还对 TRAIL 介导的细胞凋亡发挥保护作用。关于其激活 NF-kappa-B 通路的能力存在相互矛盾的信息，一些研究表明它不能诱导该通路，而其他研究则认为它具有激活 NF-kappa-B 的能力。TRAILR4/TNFRSF10D 与 TRAIL 相互作用的双重性质，既作为受体又作为抗凋亡的保护因子，强调了其在细胞对 TRAIL 信号传导反应中调节功能的复杂性。

生物活性
1.Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human TRAIL at 2 μg/mL (100 μL/well) can bind Recombinant Human DcR2 with a linear range of 15-60 ng/mL.
2.Measured by its ability to inhibit TRAIL-mediated cytotoxicity using L-929 mouse fibroblast cells treated with TRAIL. The ED50 for this effect is 1.8-7.2 ng/mL in the presence of 20 ng/mL Recombinant Human TRAIL/TNFSF10.

复溶
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底，如果粉末浮起，开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL（请注意蛋白复溶浓度不能低于0.1 mg/mL），室温平衡5-10 min保证充分溶解，复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存，建议复溶时添加载体蛋白或者稳定剂（如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖），同时将复溶后的蛋白溶液按照需求进行分装，储存于-20°C至-80°C，随取随用，避免反复冻融。
