LB Agar (Lennox)

LB Agar (Lennox) is a dehydrated powder for the preparation of nutritionally rich solid medium (plates) for the growth and maintenance of recombinant strains of E. coli in molecular biology studies.

This rich growth medium contains all the nutritional requirements for E. coli. Tryptone and Yeast Extract are the sources for carbon, nitrogen, vitamins, minerals, and amino acids essential for growth, while sodium chloride supplies essential electrolytes for transport and osmotic balance. For faster growth, the medium can be supplemented with glucose (0.1%) or glycerol (0.4%).
