    摘要: The invention relates to novel means and processes for the detection of a virus in a biological sample comprising cells infected by the virus. In particular, the invention relates to a fluorescent reporter protein designed as a recombinant inactive form of flipGFP suitable for specific activation by viral components in particular by viral proteins, such as viral protease, wherein the viral component recognizes a cleavage site inserted in the recombinant flipGFP. The fluorescent reporter protein is suitable for use in an in vitro method of detection of virus infection in a biological sample when the virus is related to the viral components activating the inactive form of flipGFP into an active fluorescent flipGFP in a biological sample, especially a sample comprising cells, in particular unaltered cells.
