Genemedi produces core diagnostic ingredients for test of Infectious disease (peptic ulcer? and gastritis) and related syndrome. GeneMedi offers paired diagnostics grade Helicobacter pylori flagellin B (flagellin B (FlaB)) antibodies (monoclonal antibody, mab) and antigens for Infectious disease (peptic ulcer? and gastritis) rapid test kit of Helicobacter pylori flagellin B (flagellin B (FlaB)) testing in standard substance, positive control, ELISA test,Lateral flow immunoassay (LFIA),colloidal gold immunochromatographic assay, Chemiluminescent immunoassay (CLIA),turbidimetric inhibition immuno assay (TINIA), immunonephelometry and POCT. All the antibodies and antigens for Infectious disease (peptic ulcer? and gastritis ) test are suitable for in functional ELISA, and other immunoassays in dignostics.The antibodies can act as a capture antibody and detection antibody. The antigens can be used as positive control.Helicobacter pylori?is a stomach-colonizing epsilon-proteobacteria present in approximately half of the global human population.?H. pylori?infection has been recognized as the major cause of gastritis and the primary risk factor for gastric cancer. Genetic and structural studies have increasingly suggested that?H. pylori?has evolved distinct mechanisms of flagellar motility that are essential for gastric colonization. The flagellar filament of?H. pylori?comprises two types of flagellins, FlaA and FlaB. FlaA is the major structural component, whereas FlaB is localized proximal to the hook. In?H. pylori, both flagellins FlaA and FlaB can evade recognition by TLR5 and used as a immunodiagnostic tool.
