1163 sLB Broth, Condalab

1163 Condalab

sLB Broth (Super Lysogeny Broth) is an exceptionally nutrient-rich liquid medium designed for the high-density cultivation of recombinant Escherichia coli strains. It is specifically formulated to provide superior biomass yields compared to standard LB Broth, making it ideal for large-scale plasmid DNA preparation and recombinant protein expression.

Add to bag

sLB Broth is an enriched modification of the classic Lysogeny Broth. It contains significantly higher concentrations of Tryptone and Yeast Extract, which supply an abundance of peptides, amino acids, vitamins, and trace elements. This high nutrient density allows bacterial cultures to sustain exponential growth for longer periods and reach much higher optical densities (OD) than traditional media. The Sodium chloride concentration is maintained at a level that ensures osmotic stability for the cells during rapid division. This medium is the liquid equivalent of sLB Agar and is a preferred choice for molecular biologists requiring maximum yields from small culture volumes.

Advantages

  • Maximum Biomass: Formulated to reach higher cell densities, resulting in significantly increased yields of plasmids and proteins.
  • Optimized for Fast Doubling: Rich nutrient profile supports rapid growth rates, reducing the time required for overnight cultures.
  • High Plasmid Stability: Provides a robust metabolic environment that helps maintain high-copy-number plasmids in host cells.
  • Versatile Base: Excellent for the addition of various antibiotics and induction agents (like IPTG) for regulated protein expression.
  • Consistent Quality: Manufactured under strict quality control to ensure reproducible growth kinetics across different experiments.
