Shigatoxin Antibody (STX-2) is a mouse monoclonal IgG1 antibody that detects Shigatoxin by western blotting (WB). Anti-Shigatoxin antibody (STX-2) plays a crucial role in the study of hemolytic uremic syndrome (HUS), which is the leading cause of acute renal failure in children globally. Shigatoxin, particularly Shigatoxin 2 (Stx2), is produced by enterohemorrhagic Escherichia coli and inhibits protein synthesis in host cells, leading to severe pathological consequences. Shigatoxin′s structure consists of an A subunit and a pentameric B subunit, which facilitates binding to specific receptors on target cell surfaces, such as globotriaosylceramide. This binding enables toxin entry into cells, where Shigatoxin exerts toxic effects, including apoptosis induction and inflammatory cytokine release. Understanding Shigatoxin′s structure is important for developing therapeutic strategies and designing inhibitors that block cellular receptor interactions. Shigatoxin monoclonal antibody (STX-2) serves as an invaluable tool for researchers investigating Stx2-induced cellular damage mechanisms and broader HUS implications.
