Fusion proteins or chimeric proteins are proteins created through the joining of two or more genes that originally coded for separate proteins. A GFP gene is often used as tag to a reporter gene. Fusion lentiverctors can be used as viral particles to produce proteins that carry for example a GFP tag. Antigen purification of recombinant fusion tag proteins is a frequent strategy using a Fralg tag.
