Biological activity was determined by its ability to inhibit Wnt3a induced alkaline phosphatase production in MC3T3-E1 cells. The expected ED50 for this effect is 40-60 ng/mL.
As with any protein, exposing WNT-7A recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
Lagerung
-20 °C
Informationen zur Lagerung
The recombinant protein is stable for at least 2 years from date of receipt at -20 °C. Reconstituted WNT-7A stable for at least 3 months when stored in working aliquots with a carrier protein at -20 °C.

Hintergrund
Wnt-7a belongs to the Wnt family of signaling proteins that play a key role in maintaining the integrity of embryonic and adult tissues. It is expressed in placenta, kidney, testis, uterus, fetal lung and fetal and adult brain. Most Wnt proteins can signal though a mechanism called the canonical Wnt pathway, in which Wnt proteins bind to and activate seven-pass transmembrane receptors of the Frizzled family ultimately leading to the disruption of ?-Catenein degradation. Intracellular accumulation of beta-Catenin increases translocation of the protein into the nucleus where it binds to TCF/LEF transcription factors and induces the expression of numerous genes. Increased Wnt/?-Catenein signaling is associated with tumorigenesis in a diverse set of human cancers. However, Wnt-7a/Frizzled-9 signaling has been shown to act as a tumor suppressor in non-small cell lung cancers. Recombinant human Wnt-7a is a 35.5 kDa glycoprotein containing 318 amino acids. Due to glycosylation, Wnt-7a migrates between 40-55 kDa by SDS-PAGE gel under unreduced conditions.
