Used in biomedical research to detect and quantify CagA protein, a key virulence factor produced by Helicobacter pylori. This ELISA kit enables researchers to study the presence and levels of CagA in clinical or experimental samples, helping to investigate its role in gastric inflammation, peptic ulcer disease, and gastric cancer development. It supports studies on host-pathogen interactions, immune response, and vaccine or therapeutic development. The kit is intended for in vitro research use only and is not for diagnostic use.
