Salivary glycoprotein 340 (gp-340) inhibits neuraminidase (NA) activity of the PR-8 strain of influenza A virus (IAV). The PR-8 strain of IAV was preincubated with the indicated concentrations of salivary gp-340 isolated from two different saliva donors. Salivary gp-340 from donor #1 caused significantly more inhibition at concentrations of 0.4 and 0.8 μg/ml compared to that of donor #2 (results mean ± SEM of four experiments).
