Mouse SFRP2, Tag Free is widely used in biological research focused on Wnt signaling pathway regulation. It serves as a critical tool for studying cell differentiation, tissue development, and cancer progression due to its role in modulating Wnt activity. Researchers use the protein in assays to investigate how inhibition of Wnt signaling affects stem cell behavior and tissue morphogenesis. It is also applied in studies of ocular neovascularization, where SFRP2 has been shown to suppress abnormal blood vessel formation. Its tag-free form allows for unmodified functional analysis, making it ideal for protein-protein interaction studies and structural characterization. Additionally, it supports the development of therapeutic strategies targeting angiogenesis and fibrosis in preclinical models.
