Intact Genomics (ig) Ar.A4 Agrobacterium Chemically Competent cells are made from a specific strain of Rhizobium rhizogenes (formerly Agrobacterium rhizogenes), Agrobacterium rhizogenes (kan R) Ar A4 Ri (agropine type). Agrobacterium rhizogenes is a soil-borne gram-negative bacterium that can infect most dicotyledons, a few monocotyledons, and some gymnosperms. Ar.A4 Agrobacterium Chemically Competent Cells are optimized for the highest transformation efficiencies and are useful for transgenic operations of corn, tobacco, carrot, and other plants. Ar.A4 Agrobacterium rhizogenes strain contains agrobacterium-type Ri plasmid and displays kanamycin resistance.Product Includes and Storage:Ar.A4 Agrobacterium Chemically Competent Cells: -80 ºCpIG7spe control DNA: -20 ºCAgro Recovery medium: 4 ºC
