Anti-Munc18-1 antibodies enable researchers to detect and measure the Munc18-1 antigen in biological samples. This target is a reported synonym of the STXBP1 gene, which encodes syntaxin binding protein 1. This protein is known to function in intracellular protein transport and the regulation of apoptosis, among other biological roles. The human version of Munc18-1 has a canonical amino acid length of 594 residues and a protein mass of 67.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane and cytoplasm of cells and notably expressed in many tissues, such as the cerebellum and cerebral cortex. Other names for this target antigen include DEE4 and N-Sec1. Western Blot is a widely used application for the Munc18-1 antibodies listed below. In addition, Immunohistochemistry is also a common application.
