CellPro™ LB + Chloramphenicol is a nutrient-rich agar medium supplemented with chloramphenicol, an antibiotic that inhibits the growth of chloramphenicol-sensitive bacterial strains. This selective medium is commonly used in microbiology and molecular biology laboratories for the cultivation of bacteria harboring chloramphenicol resistance genes. By incorporating chloramphenicol into the LB agar, this medium facilitates the isolation and propagation of genetically modified bacterial cells in a controlled and selective environment.
