Anti-RSPO antibodies enable researchers to detect and measure the RSPO antigen in biological samples. This target is a reported synonym of the RSPO1 gene, which encodes R-spondin 1. This protein is known to function in the Wnt signaling pathway and protein phosphorylation, among other biological roles. The human version of RSPO has a canonical amino acid length of 263 residues and a protein mass of 29 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and is secreted of cells. RSPO is a member of the R-spondin protein family. Indicated applications for RSPO antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
