Broad-spectrum activity of the TAT-Kα2 peptide and its specificity. Enveloped viruses, (a) VSV (293T cells) and (b) RSV (Hep2 cells), and a non-enveloped virus, (c) Coxsackievirus (HeLa cells), were tested to determine the antiviral effects of TAT-Kα2 peptide against other viruses. The 40 μM of TAT-Kα2 peptide or TAT-scramble peptide was pre-incubated with the respective viruses, cell infection was determined by GFP expression, and the titers of each virus were determined.
