Microbiology and Infectious Disease antibody


Product Description Mouse Monoclonal antibody [10E9] recognizes Helicobacter pylori CagA
Tested Reactivity H. pylori
Tested Application ELISA, WB
Specificity Cross-reaction with other proteins has not been identified.
Host Mouse
Clonality Monoclonal
Clone 10E9
Isotype IgG2a, kappa
Target Name Helicobacter pylori CagA
Immunogen A highly immunogenic 32kD CagA fragment, recombinant
Conjugation Un-conjugated

Application Instructions

Application Note ELISA: Clone 10E9 can be used as capture antibody in sandwich ELISA. Anti-CagA clone 10E9 coated wells detect recombinant CagA antigen in combination with HRP conjugated anti-CagA clone 5C6, clone 3C10 and clone 3C1. In addition, clone 10E9 selectively detected cell lysate of a CagA containing H. pylori strain when HRP conjugated anti-CagA clone 3C10 was used.

Western Blot: This clone detects the 32 kD band corresponding to the molecular weight of the recombinant CagA antigen (Immunogen).

* The dilutions indicate recommended starting dilutions and the optimal dilutions or concentrations should be determined by the scientist.

Background Helicobacter pylori (H. pylori), a spiral rod shaped gram-negative bacterium, is frequently found in the stomach. In infected populations, 10-20% may develop gastritis and gastric ulcer and 1-2% may develop cancer. The genome of H. pylori isolates from carriers with symptoms contains a 40kb pathogenicity island encoding H. pylori cytotoxin, cytotoxin associated gene A protein (CagA) and other virulence associated factors. CagA is used as a biomarker for virulent H. pylori strains.
