Lincomycin HCl is a lincosamide antibiotic with a very similar mechanism of action to macrolide antibiotics.  Lincomycin HCl is freely soluble in aqueous solution at 29.3 mg/mL.

    CAS Number


    Molecular Formula

    C18H34N2O6S · HCl · H2O

    Molecular Weight


    Mechanism of Action

    Lincosamide antibiotics inhibit bacterial growth by targeting the 50S ribosomal subunit preventing peptide bond formation and translocation during protein synthesis. Resistance to lincomycin is commonly attributed to mutations in 50S rRNA preventing lincomycin binding allowing the cell to synthesize proteins free of error.

    Storage Conditions

    2-8 °C

    Tariff Code



    Lincomycin is a broad spectrum antibiotic commonly used to target streptococcal and staphylococcal infections.


    Microbiology Applications

    Lincomycin HCl is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against gram positive and gram negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Representative MIC values include:

    • Staphylococcus aureus 0.2 µg/mL – 3.2 µg/mL
    • Streptococcus pyogenes 0.04 µg/mL – 0.8 µg/mL

    Plant Biology Applications

    In botanical applications, lincomycin is frequently used as a selection marker in chloroplast transformation. Lincomycin is typically preferred over other antibiotics for chloroplast transformation because it also inhibits callus formation, greening, and subsequent shoot regeneration. To achieve a homoplastic state during chloroplast transformation, 20 cell cycle divisions are required.
