Used for the detection and quantification of Listeriolysin O, a toxin produced by Listeria monocytogenes, in research settings. Helps in studying bacterial pathogenesis, immune response, and virulence mechanisms. Commonly applied in microbiology and immunology laboratories to assess toxin production in bacterial cultures or host cell interactions. Supports development of diagnostics and evaluation of vaccine efficacy by measuring antibody responses against Listeriolysin O. Not for diagnostic use in humans or animals.
