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.
How do I make SOC media?
(This solution is made by dissolving 18 g of glucose in 90 mL of deionized H2O. After the sugar has dissolved, adjust the volume of the solution to 100 mL with deionized H2O and sterilize by passing it through a 0.22-µm filter.)
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.
How much SOC media do I add?
Add 250-1,000 μl LB or SOC media (without antibiotic) to the bacteria and grow in 37°C shaking incubator for 45 min.
What does SOC Medium contain? – Related Questions
How long does SOC medium last?
If stored properly, the medium should be stable for at least 1 year.
Is SOC medium necessary?
SOC is not mandatory, Instead you can also use LB broth. Transformation is depends on handling, heating-cooling and quantified DNA.
Can I use LB broth instead of SOC?
From a practical standpoint, either LB or SOC works just fine as a recovery media for E. coli. The issue is more likely to be in the quality of the competent cells or your skills in transformation. If it’s a chemi-competent (temperature-shock) transformation, then having accurate temperatures & times is essential.
What is the purpose of SOC medium?
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.
Why is soc better than LB?
Compared to LB (both Lennox and Miller), SOC has twice the concentration of tryptone, same conc. of yeast Extract, a tenth (compared to Lennox) of NaCl conc., plus MgSO4, dextrose and KCl.
How does SOC media work?
Social media platforms allow users to have conversations, share information and create web content. There are many forms of social media, including blogs, micro-blogs, wikis, social networking sites, photo-sharing sites, instant messaging, video-sharing sites, podcasts, widgets, virtual worlds, and more.
What does SOC Medium do in transformation?
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.
Can I use LB broth instead of SOC?

If it’s a chemi-competent (temperature-shock) transformation, then having accurate temperatures & times is essential.
What makes SOC special vs LB?
NEB SOC outgrowth medium is made from animal-free peptone and delivers higher transformation efficiency than LB medium.
Where do you store SOC media?
SOC medium can be stored at either 4°C or Room Temperature depending on how fast it will be used. Storing at Room Temperature is convenient and adequate for short term usage (weeks to a couple of months). For long term storage, we recommend storing at 4°C.
Can you freeze SOC media?
SOC medium is a bacterial growth medium used to maximize the transformation efficiency of cells, so it’s prone to bacterial contamination (it’s the glucose – the little guys love it!). Best to aliquot and freeze the medium. Thanks to you all!
Can SOC media be stored at Room Temperature?
SOC medium can be stored at either 4°C or Room Temperature depending on how fast it will be used. Storing at Room Temperature is convenient and adequate for short term usage (weeks to a couple of months).
Does media need to be refrigerated?
Temperature and time
Culture Media: Sealed, unopened containers should be stored at room temperature 15-20°C. Opened containers should have the cap or lid carefully and securely replaced. It is important that opened containers are stored in a dry atmosphere at room temperature.
How long should you warm media for?
Changing media
2. To media change, warm up fresh culture media (section 5.1) at 37°C in water bath or incubator for at least 30 mins.
