Fig. 1From: Incorporation of a truncated form of flagellin (TFlg) into porcine circovirus type 2 virus-like particles enhances immune responses in miceSchematic representation of the SUMO-Cap and SUMO-Cap-TFlg fusion genes in this study. A 6 × His tag has been added to the N-terminal of the SUMO protein, and the stop codon TAA has been added in front of the Xho I restriction enzyme site. Arrowheads indicate the SUMO protease cleavage siteBack to article page
