Mouse RSPO1, His Tag is widely used in life science research, particularly in studies related to Wnt signaling pathway activation. It serves as a key reagent in cell culture applications to enhance Wnt pathway activity, which is critical for stem cell maintenance, proliferation, and differentiation. This protein is commonly applied in regenerative medicine research, including organoid development, where it supports the growth and self-renewal of adult stem cells in tissues such as intestine, liver, and brain. Due to the His tag, it allows for easy detection and purification, making it suitable for protein-protein interaction studies and receptor binding assays. It is also employed in screening assays for drug discovery targeting tissue regeneration and cancer pathways.
