LB Broth Miller (Powder)
These media have been widely used in molecular microbiology applications for the preparation of plasmid DNA and recombinant proteins (1,5). The media are nutrient-rich formulations which provide peptides and peptones, vitamins, and trace elements. The three formulations (Lennox, Miller and Luria) differ in the amount of sodium chloride, thus providing selection of the appropriate osmotic conditions for the particular bacterial strain and desired culture conditions. The low salt formulations, Lennox and Luria, are ideal for cultures requiring salt-sensitive antibiotics such as Zeocin™.

Directions per Liter:
Dissolve 25 grams in 800-900ml of ddH2O stirring gently until completely solubilized. Adjust pH of the medium to the desired level. Add additional water to bring the solution to 1L. Dispense into appropriate containers, loosen caps and autoclave for 15 minutes at 121ºC (15psi).
Storage and Stability:
Store powdered media at RT. Opened bottles should be capped tightly and kept in a dark, low humidity environment. Prepared media should be kept at 4°C and used within a short period of time.
BSE-Free: All raw materials of animal origin are sourced from USDA-designated BSE-Free countries.
Dust-Free: Specially milled powder blends are designed to eliminate or greatly reduce airborne particulates.
Homogeneous: Proprietary blending technology ensures complete mixing of components.
