    Meropenem, USP

    $185.00

    Meropenem is a β-lactam antibiotic in the carbapenem class, and targets the bacterial cell wall. It has found utility against extended spectrum β-lactamase (ESBL) producing Enterobacteriaceae that are resistant to many first line β-lactam antibiotics and certain cephalosporins. Meropenem is sparingly soluble in aqueous solution.

    We also offer:

    • Meropenem with Sodium Carbonate (M028) 
    Mechanism of Action β-lactams interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to β-lactams is commonly due to cells containing plasmid encoded β-lactamases. Like many carbapenems, Meropenem is highly resistant to the degradative effects of β-lactamases.
    Spectrum Meropenem is a broad-spectrum antibiotic targeting a wide range of bacteria especially those causing meningitis.
    Impurity Profile Chromotographic Purity:
    Any two major impurities: Not more than 0.3%
    Single impurity: Not more than 0.1%
    Total impurities: Not more than 0.3%
    Microbiology Applications Meropenem is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram-positive and Gram-negative microbial isolates. Meropenem has also shown high potency against high-resistant superbug strains.Medical microbiologists use AST results to recommend antibiotic treatment options.  Representative MIC values include:
    • Staphylococcus epidermidis 0.06 µg/mL - 16 µg/mL
    • Neisseria meningitis 0.002 µg/mL – 0.03 µg/mL

    Media Supplements

    Meropenem can be used as a selective agent in several types of isolation media:

    VRE Medium - VRE Selective Supplement

    Plant Biology Applications Meropenem can be used to suppress the overgrowth of Agrobacterium in tobacco, tomato, and rice transformation, with 25 mg/L suppressing outgrowth (Ogawa and Mii , 2007).

    Meropenem suppressed growth of Agrobacterium during transformation of Phalaenopsis at 5 mg/L and had no phytotoxic effect on the cells themselves (Sjahril and Mii, 2005).
