General description

Super optimal medium with catabolic repressor (SOC) medium is a glucose-rich microbial growth medium used primarily in the recovery step of Escherichia coli competent cell transformations. The culture of E.coli cells in this nutrient-rich microbial broth increases the transformation efficiency of recombinant plasmids containing toxic protein genes by inhibiting the unintended activation of the lac promoter carried on the cloning vector. SOC medium contains peptides, amino acids, water-soluble vitamins, and glucose in a low-salt formulation.

Application

SOC Medium has been used for the transformation of DH5α competent E-coli cells. It has also been used to culture white colonies post-cloning for the identification of the recombinant protein of interest.

Features and Benefits

SOC liquid provides:
  • Filter-sterilized, ready-to-use format
  • Convenient package sizes
  • Standard formulation

Despite insights gained through experimental models, the set of bacterial genes important for human infection is unclear for many of our most threatening pathogens. Klebsiella pneumoniae is a leading cause of health care-associated infections (HAIs) and commonly colonizes hospitalized patients

Precise genome engineering has become a commonplace technique for metabolic engineering. Also, insertion, deletion and alteration of genes and other functional DNA sequences are essential for understanding and engineering cells. Several techniques have been developed to this end (e.g., CRISPR/Cas-assisted

Ampicillin-resistant (Amp(r)) Salmonella enterica isolates (n = 344) representing 32 serotypes isolated from retail meats from 2002 to 2006 were tested for susceptibility to 21 other antimicrobial agents and screened for the presence of five beta-lactamase gene families (bla(CMY), bla(TEM)

In this paper, we report a useful protocol for cloning toxic protein genes. Use of the SOC medium, which is a glucose-containing rich medium, significantly improved the transformation efficiency of a recombinant plasmid containing a toxic plant subtilase SaSBT1 cDNA.
