Recombinant H. pylori CagA Protein

• Cat.No.: CagA-24H
• Product Overview: This recombinant protein contains immunodominant regions of H. pylori CagA protein with a MW of 55 kDa. It is recognized by positive samples in ELISA tests.

Specification

• Species: H.pylori
• Source: E.coli
• Description: It is known that H. pylori strains exhibit a significant degree of diversity. The great variability in the H. pylori genome may explain why not all infected individuals suffer from ulcer. Some H. pylori strains contain particular pathogenic genes such as cytokine associated gene A (CagA), while others lack these genes. The CagA protein of H. pylori has been found to be associated with more severe clinical manifestations, such as ulcer disease and gastric cancer. Thus, discrimination between potentially virulent strains may be relevant.
