How do I get SOC from SOB?
For SOC (=SOB+glucose): Make SOB, except add dH2O to a final volume of 960 ml instead of 1 L. Autoclave. When solution has cooled to 50°C (cool enough to touch with bare hands for a few seconds), add 40 ml of sterile 10% (w/v) glucose. (That's a final concentration of 0.4% glucose.)8 Jul 2021
Why is SOC medium used?
SOC Medium is a rich medium used primarily to aid recovery of bacterial competent cells following transformation. Use of SOC medium improves the molecular uptake whilst stabilizing the cells rapidly and so maximizing the efficiency of competent cells.
How to make SOB media?
SOB medium is prepared without Mg++ by dissolving 20 g bacto-tryptone, 5 g bacto-yeast extract, 2 ml of 5M sodium chloride, and 2.5 ml of 1M KCl in water to a final volume of ≈ 1000 ml (980 ml).
What is sob used for?
Super Optimal Broth (SOB medium) is a nutrient-rich bacterial growth medium used for microbiological culture, generally of Escherichia coli. This nutrient-rich microbial broth contains peptides, amino acids, water soluble vitamins and glucose in a low-salt formulations.
How to make SOC media from SOB?
on liquid cycle.) SOC medium is identical to SOB medium, except that it contains 20 mm glucose. After the SOB medium has been autoclaved, allow it to cool to 60°C or less and then add 20 ml of a sterile 1 M solution of glucose. (This solution is made by dissolving 18 g of glucose in 90 ml of deionized H,O.
What is in SOc medium?
S.O.C. Medium is supplied as 10 x 10 mL bottles of liquid medium with the following composition: 2% tryptone, 0.5% yeast extract, 10 mM NaCl, 2.5 mM KCl, 10 mM MgCl2, 10 mM MgSO4, and 20 mM glucose.
What is SOC growth medium?
SOC is a microbial growth medium used for the transformation of competent cells (E. coli). This nutrient-rich microbial broth contains peptides, amino acids, water-soluble vitamins, and glucose in a low-salt formulation.
What does SOC medium contain?
S.O.C. Medium is supplied as 10 x 10 mL bottles of liquid medium with the following composition: 2% tryptone, 0.5% yeast extract, 10 mM NaCl, 2.5 mM KCl, 10 mM MgCl2, 10 mM MgSO4, and 20 mM glucose.
What function does SOC broth serve in bacterial transformation?
What is SOC Medium? SOC medium or super optimal broth with catabolite repression medium is a microbial growth medium. The SOC medium is used for providing nutrients and supporting the recovery of Escherichia coli competent cells following transformation.
