Antigens FliD and CagA
A strong duo to detect H. pylori specific antibodies
FliD Antigen
(flagellar filament capping protein or flagellar hook-associated protein) is an essential element in the assembly of H. pylori´s flagella. It is an efficient, highly sensitive and specific marker, present in all H. pylori strains worldwide.
ImevaX holds the patent on the detection of FliD-specific antibodies.
CagA Antigen
(cytotoxin-associated antigen A) is one of the best studied and most important virulence factors. Subjects infected with H. pylori strains expressing CagA have a significant higher risk to develop complications, including gastric cancer, compared to H. pylori infections alone.
