Intact Genomics (ig) Thymidine-Auxotrophic EHA101Thy Agrobacterium ElectroCompetent Cells include modifications so that they will not grow unless 50 mg/L of thymidine is added to Minimal medium. This prevents the bacteria from overgrowing plant tissues when used for plant transformation. Thymidine-Auxotrophic EHA101Thy Agrobacterium ElectroCompetent Cells are optimized for the highest transformation efficiencies. The EHA101Thy strain is useful for transgenic operations of rice, tobacco and other plants. EHA101Thy– thyA knockout mutant, spectinomycin-resistant, derived from EHA101, itself a derivative of A281 (A136/pTiBo542).Benefits: Thymidine Auxotrophic Enables development of more efficient transformation systems Reduced bacterial overgrowth during co-cultivation Decreased need for antibiotics
