Goat anti Wnt-3 antibody recognises both human and mouse proto-oncogene Wnt-3, a member of the Wnt family, and ligand of the frizzled family of seven transmembrane receptors.

Wnt-3, otherwise known as Int-4, is involved in cell fate decisions and patterning during embryogenesis, cell signalling during neural tube development, and implicated in the tumorogenesis of several cancers including breast, lung, hepatocellular(HCC), and gastric carcinoma.

Over-expression of Wnt-3 playes a pivotal role in the resistance of HER2-overexpressing breast tumors to the breast cancer treatment drug Trastuzumab, also known as Herceptin (Wu et al. 2012). The effects of Wnt-3 over-expression included the transactivated expression of EGFR (epidermal growth factor receptor) an increased expression of B-catenin within the nucleus, an increase in N-cadherin and the neural crest transcription factor SLUG, as well as promoting an EMT (epithelial to mesenchymal transition) response.

Goat anti Wnt-3 polyclonal antibody exhibits strong fibrous staining in myoepithelial cells of human breast tissue in paraffin sections.

Goat anti Wnt-3 polyclonal antibody stains mouse hippocampal primary astrocytes in ICC/IF (Okamoto et al. 2011).

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
