ElectroMAX™ A. tumefaciens LBA4404 Cells are Agrobacterium cells that have been specially prepared for transformation by electroporation (1,2). ElectroMAX™ LBA4404 Cells contain the disarmed Ti plasmid pAL 4404, which has only the vir and ori region of the Ti plasmid (3). ElectroMAX™ LBA4404 Cells have been successfully used to transform a variety of plant species (4), including tobacco and Arabidopsis, at high efficiency (5).
