Description : R-spondin-1 is also known as Roof plate-specific Spondin 1 (RSPO1) and cysteinerich and single thrombospondin domain containing protein 3 (Cristin 3), which is a secreted protein which belongs to the R-Spondin family and encodes a secreted activator protein with two cystein-rich, furin-like domains and one thrombospondin type 1 domain. All Rspondins regulate Wnt/β-catenin signaling, but have distinct expression patterns. Like other R-Spondins, R-Spondin-1 contains two adjacent cysteinerich furinlike domains (aa 34-135) with one potential N-glycosylation site, followed by a thrombospondin (TSP1) motif (aa 147-207) and a region rich in basic residues (aa 211-263). Only the furinlike domains are needed for β-catenin stabilization. A putative nuclear localization signal at the C-terminus may allow some expression in the nucleus.
Source : HEK293

Purity : >95% as determined by SDS-PAGE.
Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20 to -70 centigrade for 12 months in lyophilized state;
-70 centigrade for 3 months under sterile conditions after reconstitution.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.

What tissue-specific processes are regulated by RSPOs, and what are some examples of these processes? 08/25/2021

RSPOs regulate various tissue-specific processes, including bone formation, skeletal muscle tissue development, proliferation of pancreatic β-cells, intestinal stem cells, and cancer progression.

Describe the purification strategy used to obtain rhRSPO1, including the chromatographic steps involved. 07/08/2021

The purification strategy for rhRSPO1 involved two sequential chromatographic steps: heparin affinity chromatography followed by molecular exclusion chromatography.

How does RSPO1 induce the Wnt pathway, and what are the downstream effects on cell proliferation, differentiation, and death? 05/19/2021

RSPO1 induces the Wnt pathway by stabilizing the Wnt receptor complex, leading to enhanced Wnt signaling and influencing cellular processes.

How was recombinant human RSPO1 (rhRSPO1) generated, and which cell line was used for this purpose? 04/08/2018

rhRSPO1 was generated using the HEK293 cell line, and the coding sequence was synthesized and subcloned into a mammalian cell expression vector.
