Output Type virus titer reduction (plaque assay) after PR8 infection
Output Value
Output Units
Output Notes T9(dR)+siNP reduced PR8 viral titers in MDCK and A549 vs controls; reported higher inhibition efficiency than TP-delivered siNP (Figure 5).
Toxicity Notes MTT: cell viability not substantially affected at 10 µM; estimated LD50 ~85 µM in 293T; reported low cytotoxicity vs TP.
