The following R-Spondin 4 ELISA kits are useful research tools for the measurement of R-spondin 4 in biological samples. In humans this protein is encoded by the RSPO4 gene. This protein is reported to be an activator of the canonical Wnt signaling pathway by acting as a ligand for LGR4-6 receptors. The canonical protein structure is reported to have an amino acid length of 234 residues, a mass of 26.2 kDa, and is a member of the R-spondin protein family. It has been described to be a secreted protein. As many as 2 protein isoforms have been reported. In certain instances, it is also post-translationally phosphorylated and glycosylated. The gene encoding this protein has been associated with the disease, Nail disorder. This protein may also be known as hRspo4, roof plate-specific spondin-4, and R-spondin family, member 4.
Some R-spondin 4 ELISA kits can detect targets at levels as low as 31.2 pg/mL and as high as 2200 pg/mL. Use the search filters to narrow your search and click on the ELISA kits below for more detailed information, such as reactivity and assay sensitivity.
