Ace Infectious produces multiple strains of inactivated H. pylori as whole-cell vaccine antigens. The genome of H. pylori is highly variable, with significant allelic and sequence diversity even among well-characterized strains. Therefore, the isolation and collection of H. pylori strains is a huge project. Fortunately, based on our long-term efforts in H. pylori, we have accumulated a rich collection of H. pylori strains from Africa, Asia, Europe, and the Americas. We also offer a wide range of chemical and physical inactivation methods to inactivate H. pylori, including the use of formalin, chloroform, phenol, ammonium sulfate, heat, sonication, and lysis with sodium dodecyl sulfate (SDS) or sodium hydroxide at pH 9.5. For a specific request for an inactivated H. pylori strain or inactivation method, you can consult our technical support staff.
