Plasmid Selection in Escherichia coli: Selects for bla (beta-lactamase) plasmids in liquid and agar media, reducing satellite colonies compared to ampicillin.

Cloning and Transformation Workflows: Plates transformants on carbenicillin-containing agar to isolate recombinant colonies after ligation or Gibson/Golden Gate assembly.

Plasmid Maintenance During Protein Expression: Maintains selection of expression vectors in Escherichia coli cultures during induction and scale-up.

High-Stability Ampicillin Alternative: Provides greater beta-lactam stability in culture, supporting longer incubations and higher-density growth.

Plant Transformation Support: Suppresses/eliminates residual Agrobacterium tumefaciens after co-cultivation to protect plant tissues.

Selective Suppression of Contaminants: Broad anti–Gram-negative activity (including Pseudomonas aeruginosa) for reducing unwanted bacterial background in experimental setups.
