Anti-Synaptotagmin IV antibodies enable researchers to detect and measure the Synaptotagmin IV antigen in biological samples. This target is a reported synonym of the SYT4 gene, which encodes synaptotagmin 4. This protein is known to function in cell differentiation, among other biological roles. The human version of Synaptotagmin IV has a canonical amino acid length of 425 residues and a protein mass of 48 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasmic vesicles of cells. Other names for this target antigen include HsT1192 and synaptotagmin IV. These Synaptotagmin IV antibodies are widely used in Western Blot experiments, among other applications.
