Here, we describe an efficient system for epitope tagging cloned genes by CD tagging using a mini-Tn10 transposon delivery vector. The system was tested against a lambdaFIX genomic clone of the human nucleolin gene. Transfection of HeLa cells with the tagged gene led to the expression of both the appropriately spliced tagged transcript and the appropriately localized tagged protein.
