Fig. 4From: Identification of a novel linear epitope on the NS1 protein of avian influenza virusDetection of the selected phages for MAb D9 binding by phage ELISA. After three successive rounds of biopanning, phage ELISA was performed for further identification of the positive phage clones that were successfully sequenced. An irrelevant MAb was used as a negative control. Error bars represent the standard deviation of the results from three replicate experimentsBack to article page
