LLO (190-201) (Listeriolysin O 190 peptide) is a biological active peptide. (This peptide is a major histocompatibility complex class II (MHC-II)-restricted peptide, LLO190 (NEKYAQAYPNVS), from the listeriolysin O protein of Listeria monocytogenes, which generates an LLO190-specific Th response. This peptide subsequently challenge recombinant L. monocytogenes expressing the MHC-I-restricted epitope of ovalbumin (Ova257, SIINFEKL).)

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
