Hemagglutination (HA) inhibition caused by purified salivary proteins (μg/ml)

Phil82 PR-8 Sendai virus
MUC5B 0.65 ± 0.05 2.1 ± 0.9 4.6 ± 0.9
Lactoferrin >12.5 >12.5
Salivary gp-340 0.22 ± 7 0.05 ± 0.01 0.13 ± 0.02
Thrombospondin >7.5 ≥4.4

Results are mean ± SEM of three or more experiments and are expressed as μg/ml of the indicated purified proteins required to inhibit HA activity of 40 HA units of the Phil82 or PR-8 strain of influenza A virus or Sendai virus. Thrombospondin had detectable HA inhibitory activity against the PR-8 strain of IAV in three of five experiments and not in the other two (hence, ≥4.4).
