Recombinant Human DKK1 Protein (Thr32-His266), Tag Free
Product Description
Cat
IMP-9833
Official Symbol
DKK1
Product Overview
Recombinant human Dkk-1 protein (Thr32-His266) without tag was expressed in Spodoptera frugiperda, Sf 21 (baculovirus) cells.
Description
This gene encodes a member of the dickkopf family of proteins. Members of this family are secreted proteins characterized by two cysteine-rich domains that mediate protein-protein interactions. The encoded protein binds to the LRP6 co-receptor and inhibits beta-catenin-dependent Wnt signaling. This gene plays a role in embryonic development and may be important in bone formation in adults. Elevated expression of this gene has been observed in numerous human cancers and this protein may promote proliferation, invasion and growth in cancer cell lines.
Expression System

Form
Lyophilized from a 0.2 μm filtered solution in PBS with BSA as a carrier protein.
Molecular Mass
Predicted Molecular Mass: 25.8 kDa
SDS-PAGE: 33-38 kDa, reducing conditions
Protein length
Thr32-His266
Bio-activity
Measured by its ability to inhibit Wnt induced TCF reporter activity in HEK293 human embryonic kidney cells. Recombinant Human Dkk-1 inhibits a constant dose of 500 ng/mL of Recombinant Human Wnt-3a. The ED50 for this effect is 10-60 ng/mL.
Endotoxin
<1.0 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE with silver 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 containing at least 0.1% human or bovine serum albumin.
SDS-PAGE
SDS-PAGE
