Recombinant Human Dkk-1 Protein (RP01343)

Recombinant Human Dkk-1 Protein was determined by SDS-PAGE with Coomassie Blue, showing bands at 40-45 kDa.

Immobilized Human DKK-1 at 5 μg/mL (100 μL/well) can bind Human LRP-5 with a linear range of 0.027-0.559 μg/mL.

Recombinant Human Dkk-1 inhibit Wnt3a-induced alkaline phosphatase production by C3H10T1/2 cells. The EC₅₀ for this effect is approximately 95 ng/ml in the presence of 2 μg/mL of Recombinant Human Wnt3a.

生物活性

1.Measured by its binding ability in a functional ELISA.Immobilized Human DKK-1 at 5 μg/mL (100 μL/well) can bind Human LRP-5 with a linear range of 0.027-0.559 μg/mL.
2.Measured by its ability to inhibit Wnt3a-induced alkaline phosphatase production by C3H10T1/2 cells. The EC₅₀ for this effect is approximately 95 ng/ml in the presence of 2 μg/mL of Recombinant Human Wnt3a.

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。

背景信息

Members of the dickkopf-related protein family (DKK-1, -2, -3, and -4) are secreted proteins with two cysteine-rich domains separated by a linker region. And DKK1 takes part in embryonic development through its inhibition of the WNT signaling pathway, binds to LRP6 with high affinity and prevents the Frizzled-Wnt-LRP6 complex formation in response to Wnts. DKK1 promotes LRP6 internalization and degradation when it forms a ternary complex with the cell surface receptor Kremen.DKK1 not olny functions as a head inducer during development, but also regulates joint remodeling and bone formation, which suggests roles for DKK1 in the pathogenesis of rheumatoid arthritis and multiple myeloma. More recently research reported, DKK1 impacts eye development from a defined developmental time point on, and is critical for lens separation from the surface ectoderm via β-catenin mediated Pdgfrα and E-cadherin expression.
