Figure 3From: Induction of IL-6 and CCL5 (RANTES) in human respiratory epithelial (A549) cells by clinical isolates of respiratory syncytial virus is strain specificViral replication kinetics of NH1067 and NH1125. Intracellular viral genomic RNA levels were determined by real time reverse transcriptase PCR. RNA quantity is displayed as pfu equivalents based on a standard curve (data not shown).Back to article page
