Technical Data
Dkk-2 (DKK2, SK, DKK-2, Dickkopf Homolog 2 (Xenopus laevis), Dickkopf-2 Like, Dickkopf (Xenopus laevis) Homolog 2)
Analysis of individual DKK domains and chimeric DKKs shows that the carboxy-terminal domains of both DKK1 and DKK2 associate with LRP6 and are necessary and sufficient for Wnt8 inhibition. Xenopus Dickkopf 1 (DKK1) was initially discovered as a Wnt antagonist that plays an important role in head formation. By far, four members of DKK have been identified in mammals. Each DKK molecule contains two conserved cysteine-rich domains. Recent studies showed that the second Cys-rich domains of DKK1 and DKK2 inhibited Wnt3a-activated signaling, whereas the first Cys-rich domains had no effects. In addition, the second Cys-rich domain of DKK2, but not that of DKK1, was able to activate the canonical pathway in the presence of LRP6, and this LRP-dependent signaling does not require Dvl.

Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
