Anti-S1P4 antibodies enable researchers to detect and measure the S1P4 antigen in biological samples. This target is a reported synonym of the S1PR4 gene, which encodes sphingosine-1-phosphate receptor 4. This protein is known to function in GPCR signaling pathways and immune response pathways, among other biological roles. The human version of S1P4 has a canonical amino acid length of 384 residues and a protein mass of 41.6 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include EDG6 and LPC1. Western Blot is a widely used application for the S1P4 antibodies listed below. In addition, ELISA is also a common application.
