However, current methods to detect virus-specific antibodies are often resource-intensive and impractical for deployment in outbreak settings or in field-based studies. This manuscript presents two economical, high-throughput immunoassays\u2014the cytoblot immunoassay (CBA) and strip immunoblot assay (SIA)\u2014for detecting and quantifying anti-lymphocytic choriomeningitis mammarenavirus (LCMV) antibodies in mouse serum. To validate, we tested serum from acutely or persistently experimentally infected mice. Both assays detected LCMV-specific IgG and IgM antibodies with high sensitivity and specificity across multiple timepoints. By facilitating the study of immune responses in rodent reservoirs, these tools can enhance our understanding of zoonotic viral transmission, provide scalable platforms for outbreak preparedness, and serve as adaptable models for the development of rapid serological assays for other viral pathogens.<\/jats:p>","DOI":"10.64898\/2026.04.07.716918","type":"posted-content","created":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T05:20:17Z","timestamp":1775712017000},"source":"Crossref","is-referenced-by-count":0,"title":["Development
