Part of the Wnt family proteins and important in cell signaling, Wnt-3a is a lipidmodified, secreted hydrophobic glycoprotein with 24 conserved cysteine residues encoded from structurally related genes. Wnt family proteins have been implicated in oncogenesis and in multiple developmental processes including regulation of cell fate and patterning during embryogenesis. Wnts are ligandsfor seven-pass transmembrane receptors of the frizzled family. Wnts binds Frizzled receptors and forms complex with low-density lipoprotein receptor-related protein (LRP5 or LRP6) which results in the stabilization of intracellular betacatenin levels. Intracellular accumulation of beta-catenin increases translocation of the protein into the nucleus, where it binds to TCF/LEF transcription factors to promote expression of Wnt target genes. Lack of Wnt signaling disrupts transcriptional activation of tumor suppressor genes which is linked to neoplastic transformation, oncogenesis, and human degenerative disease. Wnt-3a is required for normal embryonic mesoderm development and formation of caudal somites. It is also required for normal morphogenesis of the developing neural tube. Wnt-3a mediates self-renewal of the stem cells at the bottom on intestinal crypts.

• Learn more about our Recombinant Proteins. - How does the activity of your recombinant proteins compare to competitors?
-
We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!
- What is the specific activity or ED50 of my recombinant protein?
-
The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.
- Have your recombinants been tested for stability?
-
Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.
- Does specific activity of a recombinant protein vary between lots?
-
Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.
- How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
-
Use formula Specific activity (Units/mg) = 10^6/ ED50 (ng/mL)
