Anti-Synaptotagmin XI antibodies enable researchers to detect and measure the Synaptotagmin XI antigen in biological samples. This target is a reported synonym of the SYT11 gene, which encodes synaptotagmin 11. This protein is known to function in autophagy pathways and cytokine-mediated signaling pathways, among other biological roles. The human version of Synaptotagmin XI has a canonical amino acid length of 431 residues and a protein mass of 48.3 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in many tissues, such as the appendix and cerebellum. Other names for this target antigen include SYT12, sytXI, and synaptotagmin XI. A number of Synaptotagmin XI antibodies have been mentioned in research publications and have associated citations. Immunofluorescence is a widely used application for these antibodies. ELISA, Western Blot, and Immunocytochemistry are also common applications.
