Description

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
