Intact Genomics (ig) Methionine-Auxotrophic LBA4404Met Electrocompetent Agrobacterium cells include modifications so that they will not grow unless free methionine is added to Minimal medium. This prevents the bacteria from overgrowing plant tissues when used for plant transformation. Methionine-Auxotrophic LBA4404Met Electrocompetent Agrobacterium cells are optimized for the highest transformation efficiencies. The LBA4404Met strain is useful for transgenic operations of tomatoes, tobacco and other plants. LBA4404Met contains a rifampicin resistance gene (rif). LBA4404Met strain also contains an octopine-type Ti plasmid pAL4404Met without self-transport function, which contains the vir gene.Benefits Methionine Auxotrophic Enables development of more efficient transformation systems Reduced bacterial overgrowth during co-cultivation Decreased need for antibiotics
