These Munc18-1 ELISA kits are immunodetection tools for measuring the levels of Munc18-1 in biological samples. Munc18-1 is an alias of the human STXBP1 gene, which encodes the protein, syntaxin binding protein 1. Notably, Munc18-1 is known to play a role in intracellular protein transport and the regulation of apoptosis, among other functions. The STXBP1 protein is 594 amino acid residues in length and 67.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the membrane and cytoplasm of the cell. Other names for this target antigen include DEE4 and N-Sec1.
