Plasmid Selection in Escherichia coli: Maintains AmpR (bla) plasmids in cloning and protein expression workflows using carbenicillin-supplemented LB agar/broth.

Ampicillin Alternative: Provides greater stability than ampicillin in media, reducing satellite colony formation on selection plates.

Bacterial Contamination Control: Broad-spectrum β-lactam used to suppress unwanted bacterial growth in laboratory media and buffers.

Plant Transformation Workflows: Applied in plant tissue culture to suppress/eliminate Agrobacterium tumefaciens after transformation and during regeneration.

Agrobacterium Vector Maintenance: Selects for AmpR-bearing binary vectors in Agrobacterium tumefaciens cultures.

Pseudomonas Applications: Utilized for selection or inhibition studies involving Pseudomonas aeruginosa and other Gram-negative bacteria sensitive to carbenicillin.

Routine Media Supplementation: Added to LB, TB, and other bacterial growth media for selective cultivation of transformed cells.

Competent Cell Workflows: Used post-transformation to recover and select recombinants carrying β-lactamase–conferring plasmids.
