LLO (190-201)
Based on 1 Customer Validation
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).)
