Intact Genomics (ig®) MSU440 Electrocompetent Agrobacterium cells are made from a specific strain of Rhizobium rhizogenes (formerly Agrobacterium rhizogenes), Agrobacterium rhizogenes(str R) MSU440 Ri (agropine type). Agrobacterium rhizogenes is a soil-borne gram-negative bacterium that can infect most dicotyledons, a few monocotyledons and some gymnosperms.  MSU440 Electrocompetent Agrobacterium are optimized for the highest transformation efficiencies and are useful for transgenic operations of corn, tobacco, wormwood, tea tree and other plants.  MSU440 Agrobacterium rhizogenes strain contains agrobacterium-type Ri plasmid and displays streptomycin resistance.

Transformation efficiency is tested by using the pCAMBIA1391z control DNA supplied with the kit and using the protocol in this manual. Transformation efficiency should be ?1 x 107 CFU/µg pCAMBIA1391z DNA. Untransformed cells are tested for appropriate antibiotic sensitivity.
