Rifampicin Solution is fully soluble in water, our pre-made stock solutions is easy to handle and safer then the methanol or DMSO solution alternatives. This aqueous formulation is easy to use simply add 1ml to 3ml per liter of desired media.

Rifampicin is a broad-spectrum antibiotic, it is not soluble in water and is mostly sold in powder forms. Weighting small amounts of Rifampicin is a tedious job and it can be difficult to avoid human inhalation. Normally stock solution of Rifampicin is prepared by dissolving it in methanol which is toxin to many plant cells as well as other cells. Our Aqueous solution of Rifampicin is much more user-friendly and non-toxic to these cells.

    Mechanism of Action

    Rifampicin targets prokaryotic DNA dependent RNA polymerases which prevent subsequent RNA transcription and protein translation.

    Storage Conditions

    Protect from light at ­20°C.


    Rifampicin is a broad-spectrum antibiotic targeting a wide range of gram positive, gram negative, and Mycobacterium species.



    Microbiology Applications

    Rifampicin is commonly used in bacterial recombinant protein expression to inhibit bacterial RNA polymerase activity and synthesis of host bacterial proteins. Rifampicin can also be used as a selective agent to isolate Campylobacter jejuni. Rose et al. used rifampicin from TOKU-E in methacrylate-based copolymer films and studied its effects on biofilm formation: "Prevention of Biofilm Formation by Methacrylate-Based Copolymer Films Loaded With Rifampin, Clarithromycin, Doxycycline Alone or in Combination."

    Plant Biology Applications

    Rifampicin has been tested in Jerusalem artichoke tuber explants by adding 10 to 50 µg/ml to the tissue culture medium. At 50 µg/ml no bacterial infection was detectable, without affecting cell division rates, cytodifferentiation and DNA synthesis. As a result, Rifampicin was used as antibacterial in the following experiments of this university department (Philips, 1981).
