Anti-SYD antibodies enable researchers to detect and measure the SYD antigen in biological samples. This target is a reported synonym of the MAPK8IP3 gene, which encodes mitogen-activated protein kinase 8 interacting protein 3. This protein is known to function in neuronal development and the regulation of apoptosis, among other biological roles. The human version of SYD has a canonical amino acid length of 1336 residues and a protein mass of 147.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasmic vesicles, Golgi, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include JIP-3, JIP3, and JSAP1. Western Blot is a widely used application for the SYD antibodies listed below. In addition, ELISA is also a common application.
