Recombinant Human DKK2 Protein (Met1-Ile259)
Product Description
Cat
IMP-9863
Official Symbol
DKK2
Product Overview
Recombinant human Dkk-2 protein (Met1-Ile259) without tag was expressed in Chinese Hamster Ovary cell line.
Description
This gene encodes a protein that is a member of the dickkopf family. The secreted protein contains two cysteine rich regions and is involved in embryonic development through its interactions with the Wnt signaling pathway. It can act as either an agonist or antagonist of Wnt/beta-catenin signaling, depending on the cellular context and the presence of the co-factor kremen 2. Activity of this protein is also modulated by binding to the Wnt co-receptor LDL-receptor related protein 6 (LRP6).
Expression System

Ser26
Form
Lyophilized from a 0.2 μm filtered solution in PBS and EDTA with BSA as a carrier protein.
Molecular Mass
Predicted Molecular Mass: 25.8 kDa
SDS-PAGE: 32-36 kDa, reducing conditions
Protein length
Met1-Ile259
Bio-activity
Measured by its ability to inhibit Wnt induced TCF reporter activity in HEK293 human embryonic kidney cells. Recombinant Human Dkk-2 inhibits a constant dose of 500 ng/mL of Recombinant Human Wnt-3a. The ED50 for this effect is 50-300 ng/mL.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution
Reconstitute at 100 μg/mL in PBS.
