This monoclonal antibody provides sensitive, specific detection of Escherichia coli Shiga‑like Toxin 2 (STX2), a major virulence factor associated with severe gastrointestinal disease. Clone 1A10 delivers strong affinity and low background in ELISA, Western blotting, and antigen‑capture assays, enabling precise detection in culture supernatants, clinical research samples, and purified toxin preparations. MSTX‑55A‑1A10 is ideal for diagnostic development, food safety testing, and research on toxin‑mediated pathogenesis. Its consistent performance ensures reliable detection across repeated assays.
