WNT-1, Recombinant, Human (Human WNT-1, WNT-1, WNT1, WNT 1, h-WNT-1, rh-WNT-1, recombinant human WNT-1, recombinant WNT-1, WNT)

Wnt-1 is a secreted protein that signals through the Frizzled family of cell surface receptors and is required for normal embryonic development. Wnt-1 activation induces a complex signaling cascade that ultimately leads to the increased expression of over fifty genes. An important component of Wnt-1 signaling is the stabilization, and resulting accumulation, of the intraCellular signaling protein, b-catenine. Wnt signaling induces and maintains the transformed phenotype and, in certain embryonic cell lines, supports self renewal in the absence of significant differentiation. Elevated levels of Wnt proteins are associated with tumorigenesis and are present in numerous human breast cancers. Mature human Wnt-1 is a glycosylated protein containing 343aa residues. Recombinant human Wnt-1 is a 38.4kD. non-glycosylated protein containing 343aa residues.\n\nSource:\nRecombinant protein coresponding to human WNT-1 expressed in E.coli.\n\nMolecular Weight:\n~38kD\n\nBiological Activity:\nThe ED50 was determined by its ability to enhance BMP-2 induced alkaline phosphatase production by murine ATDC5 cells. The expected ED50 for this effect is ~1.5-2.5ng/ml in the presence of ~200ng/ml of human BMP-2.\n\nEndotoxin:\n~0.1ng/ug\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 6 months at -20 degrees C. 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.
