Fig. 3From: Cirsimaritin inhibits influenza A virus replication by downregulating the NF-κB signal transduction pathwayInhibitory effect of CST on viral hemagglutination and NA. a Effects of CST on HI determined by chicken erythrocyte aggregation. b Effects of CST on IAV NA activity as examined by quantifying the fluorescent product upon 4-methylumbelliferyl- a-D-N-acetylneuraminic acid cleavage. Data are expressed as mean ± SD, and the results represent the average findings of three independent experimentsBack to article page
