Human DKK1 / Dkk-1 Protein (His Tag)

DKK-1,SK

Catalog Number P10170-H08H
Organism Species Human
Host Human Cells
Synonyms DKK-1,SK
Molecular Weight The recombinant human DKK1 protein consists of 235 amino acids and has a calculated molecular mass of 25.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh DKK1 is approximately 45 kDa due to glycosylation.
predicted N Thr 32 or Ser 35
SDS-PAGE
Purity > 90 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the human DKK1 precursor (NP_036374.1) (Met 2-His 266) was expressed with a C-terminal polyhistidine tag.
Bio-activity Measured by its ability to inhibit Wnt3a-induced alkaline phosphatase production by C3H10T1/2 cells. The ED50 for this effect is approximately 0.1-0.4 μg/ml in the presence of 10 ng/mL of mouse Wnt3a.
Research Area Cardiovascular |Blood |Other in Blood
Formulation Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background Dickkopf (DKK) family proteins, consisting of DKK-1, DKK-2, DKK-3 and DKK-4, function as secreted Wnt antagonists by inhibiting Wnt coreceptors LRP5/6. DKK-1, DKK-2, and DKK-4 also bind cell surface Kremen-1 or Kremen-2 and promote the internalization of LRP5/6. Dickkopf related protein 1 (DKK-1) was initially identified as an inducer of head formation in Xenopus embryos. DKK-1 protein modulates Wnt signaling pathway during embryonic development. Increased levels of DKK-1 are found in the majority of lung cancers, esophageal squamous cell carcinomas, and hormone-resistant breast cancers, while DKK-1 expression is decreased in malignant melanoma and colorectal cancers.
