Research Products International Corp Rifampicin, 5 Grams

Rifampicin is an antibiotic used for its potent antibacterial properties. It belongs to the class of antibiotics known as rifamycins. Rifampicin is particularly effective against bacteria, including Mycobacterium tuberculosis, which causes tuberculosis, and other bacteria that can lead to various infections.

The mechanism of action of rifampicin involves inhibiting bacterial RNA synthesis by binding to the beta subunit of bacterial DNA-dependent RNA polymerase. This interference disrupts the transcription process, preventing the synthesis of essential RNA and proteins needed for bacterial growth and survival.

Rifampicin is often used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Its use contributes to the identification and study of specific bacterial strains.
