RSPO4 ELISA kits are immunoassay tools for the measurement of the protein R-spondin 4, which is encoded by the RSPO4 gene in humans. Functionally, 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 is known to be secreted. As many as 2 protein isoforms have been reported. The protein has been noted to be post-translationally phosphorylated and glycosylated. The RSPO4 gene has been associated with the disease, Nail disorder. Other alias names for this target include hRspo4, roof plate-specific spondin-4, and R-spondin family, member 4.
There are RSPO4 ELISA kits that can detect a target at concentrations as low as 20 ng/L and as high as 10 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
