Recombinant Porcine IFN‑ gamma (Catalog # 985-PI) reduces the Encephalomyocarditis Virus (EMCV)-induced cytopathy in the PK‑15 porcine kidney epithelial cell line in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Inhibition of EMCV activity elicited by Recombinant Porcine IFN‑ gamma (0.2 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Porcine IFN‑ gamma Antigen Affinity-purified Polyclonal Antibody (Catalog # AF985). The ND50 is typically 0.6-3.0 µg/mL.
