Gibco™ LB Broth (1X) 

Description

LB broth (Lennox formulation) is a ready-to-use liquid growth medium used for bacterial culture. Gibco LB Broth is filter-sterilized and can be used for nearly all applications that require a liquid bacteria culturing step, such as protein expression, cloning, and expansion.

LB broth is one of the most referenced bacterial media for cultivating and maintaining E. coli strains. Our LB broth is based on the Lennox formulation, one of the most commonly used formulations for LB medium.

Gibco media bottles

Each media bottle features an angled opening for simplified pipetting. The 1-L Gibco media bottle uses 39% less source material (33% less for the 500-mL bottle) than comparable media bottles on the market. The cap and bottle are made from high-density polyethylene (HDPE) and polyethylene terephthalate (PETE) and can both be recycled.
