Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Ligand for members of the frizzled family of seven transmembrane receptors. Plays a role in ventral mesodermal patterning during embryogenesis. Mimics Nieuwkoop center activity. Causes dorsal mesodermal differentiation of animal cap ectoderm when coexpressed with noggin and nuclear, sequence-specific DNA-binding protein xBra. None of these molecules causes dorsal mesoderm formation when expressed alone.

  2. EFHC1 domains are involved in ciliary localization, ciliogenesis, and the regulation of Wnt8a signaling PMID: 26783883
  3. Sulf1 inhibits the ability of Wnt8a to activate the canonical Wnt signalling pathway. PMID: 25681501
  4. study presents the structure of Xenopus Wnt8 (XWnt8) in complex with the mouse Fz8-cysteine-rich domain to a resolution of 3.25 A PMID: 22653731
  5. Xwnt8 directly initiates expression of labial Hox genes. PMID: 19623617
  6. Wnt8 conveyed by Frizzled-related proteins can activate canonical Wnt signalling despite the function of Frizzled-related proteins as Wnt inhibitors, suggesting a novel regulatory system for Wnts by sFRPs PMID: 19906850
  7. by performing gain- and loss-of-function of Wnt signaling experiments, we show that this pathway plays an important role not only in neural crest induction but also in the specification of the neural crest competence territory PMID: 14699582
  8. Wnt8 may stimulate a cellular phosphatase to dephosphorylate and activate CKIepsilon PMID: 14722104
  9. Molecular modeling of the complex between the xWNT8 protein and the CRD domain of mFZD8 PMID: 17506343
  10. Xwnt8-mediated posteriorization is restricted to the eye level and is independent of mesoderm formation. PMID: 18318733
  11. Fgf8a induces neural crest (NC) indirectly through the activation of Wnt8 in the paraxial mesoderm, which in turn promotes NC formation in the overlying ectoderm primed by Bmp antagonists. PMID: 18997112
