Background
R-spondins are secretory proteins localized in the endoplasmic reticulum and Golgi bodies and are processed through the secretory pathway. The RSPO family comprises four proteins, i.e., R-spondin 1-4, which are important secreted regulators of the Wnt/尾-catenin and Wnt/PCP signaling pathway and govern various functions and are involved in vital cellular processes such as stem cell renewal, morphogenesis and, tumorigenesis. Among the R-spondin family, R-spondin-2, is a key protein that regulates ligand-dependent 尾-catenin signaling. And it has been reported to play a pivotal role in myogenesis, osteoblast differentiation, and limb specification during embryonic development.

Usage guide
| Storage | Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week. |
|---|
| Reconstitution | Centrifμge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. |
