Enhanced PiggyBac transposon and methods for transposon mutagenesis

摘要

PiggyBac transposons and transposases with enhanced transposition activity in cells are provided. Also provided are associated methods and kits for both introducing exogenous DNA inserts into the genomes of host cells as well as for the removal of the inserts from the host cell genomes. Cells obtained by use of the compositions, methods and kits are also provided.
