TEKnova's pre-poured plates will save you time. No more media preparation, autoclaving, pouring and the aggravation of doing it over and over again. LB (Luria-Bertani) plates contain 1% tryptone, 0.5% yeast extract, 1.0% NaCl, and 1.5% agar unless otherwise indicated. LB medium is adjusted to a final pH of 7.0 unless otherwise indicated. All plates are tested with at least 4 different recombinant strains of E. coli to demonstrate the efficacy of the antibiotics and colorimetric indicators contained within.
