Figure 4From: Application of bioinformatics-coupled experimental analysis reveals a new transport-competent nuclear localization signal in the nucleoprotein of Influenza A virus strainImmunoblot analysis of NP-GFP constructs. All NP-GFP plasmid constructs and the empty vector C2-GFP (control) were transfected into COS-7L cells and cell lysates were analyzed to confirm expression of the fusion proteins. Molecular weight markers (in kDa) are indicated on the left. The caspase-cleaved N-terminal fragment of NP-L is indicated by an asterisk (*).Back to article page
