Description

Bacitracin F, EvoPure® is a highly purified form of Bacitracin fraction F.  The EvoPure line of Bacitracins are bioactive, non-toxic congeners that have not shown toxicity to cell lines in eukaryotic cell culture.

Bacitracin F, EvoPure can be used to study properties and characteristics of Bacitracin F separately from other Bacitracin compounds found in  standard grade bacitracin. Bacitracin F, EvoPure can also be used as an analytical standard.

    CAS Number

    22601-63-4

    Molecular Formula

    C66H98N16O17S

    Molecular Weight

    1419.65 g/mol

    Mechanism of Action

    Bacitracin prevents phosphorylation of bactoprenol, a transport protein which carries peptidoglycan components outside the cell membrane. Without the active phosphorylated bactoprenol, peptidoglycan synthesis cannot be completed and the cell lyses. Resistance to Bacitracin is understood to involve two mechanisms: A protein transporter (BcrABC) which pumps bacitracin out of the cell after it has entered, and via another protein (BacA) which provides the active phosphorylated bactoprenol from a different synthetic pathway.

    Storage Conditions

    -20°C

    Tariff Code

    2941.90.5000

    Spectrum

    Bacitracin primarily targets the cell wall in members of the Gram-positive bacteria including Streptococcus pyogenes and Staphylococcus aureus.

Applications

    Eukaryotic Cell Culture Applications

    Bacitracin can be used for gene selection in cell culture. TOKU-E tested the Selectivity Factor values for the different grades of Bacitracin, and found that range was 41- 350 CulturePure grade versus 2-126 for USP grade, for the cell lines tested (HEK293, NIH/3T3, 293T, CHO-k1, B16).

    Microbiology Applications

    Bacitracin is a useful tool to differentiate between ß-hemolytic, group A Streptococci (Streptococcus pyogenes) and ß-hemolytic Streptocococci of other groups. Bacitracin can be used as a supplement in chocolate agar to facilitate the isolation of Haemophilus influenzae. Bacitracin can be used to study the regulatory network in B. subtilis. By systematically analyzing the Bacitracin stimulon, authors can pinpoint the loci induced by Bacitracin (Mascher et al 2003).

    Plant Biology Applications

    Tobacco hairy roots and cell suspensions were used in plant transformation studies to produce full length murine IgG1 monoclonal antibody. Bacitracin has been shown to prevent degradation of peptides and hormones in plant systems. Treatment with Bacitracin was not sufficient to prevent loss of antibody from the cultures, but improved the growth rates by up to 53%. (Sharp and Doran, 1999).
