  • 产品描述：

    Recombinant Helicobacter pylori Vacuolating cytotoxin autotransporter(vacA) is a partial-length protein derived from E.coli. The expression region of this protein is the 1018-1290aa of Helicobacter pylori vacA. It carries an N-terminal 6xHis-B2M-tag and has a calculated molecular weight of 43.6 kDa. Its purity is greater than 90% as determined by SDS-PAGE and its identity was validated by the LC-MS/MS Analysis. This recombinant vacA protein may be used to generate specific antibodies and in microbiology research.

    VacA is one of the predominant protein toxins secreted by the type V auto-transport secretion system of the Helicobacter pylori (H. pylori). The H. pylori is a pathogenic bacterium that potentially causes peptic ulcers of the human stomach even gastric cancer. VacA is important for H. pylori colonization in vivo and has the capacity of causing "vacuole"-like membrane vesicles in the cytoplasm of gastric cells. Besides, it has other effects on target cells, including disturbing mitochondrial functions, stimulating apoptosis, and blocking T cell proliferation.
