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

Transformation efficiency is tested by using the pIG7-spe control DNA supplied with the kit and using the protocol in this manual. Transformation efficiency should be ?1 x 107 CFU/µg pIG7-spe DNA. Untransformed cells are tested for appropriate antibiotic sensitivity.
