Other Detox

Our DetoxCTM, DetoxETM, and DetoxET7TM strains are not compatible with plasmids with pACYC replication origins. In addition, these cell strains are chloramphenicol resistant. Plasmids with chloramphenicol resistance selection markers cannot be selected in these cell strains. Here we have other detoxification strains that are compatible with different plasmids, with different antibiotic resistances, and express different levels of lacI repressor.

Strain names ending with "a", "b", and "c" are used for cloning and expression with E.coli RNA polymerase, expression only with E.coli RNA polymerase and expression with T7 RNA polymerase respectively. These strains express comparable level of lacI. All of our detoxification strains express lacI consecutively. Cell strains with low, medium, and high level of lacI express about 10, 20 to 50, and 100 times more lacI repressor than indigenous level respectively. DetoxCTM, DetoxETM, and DetoxET7TM strains express medium level of lacI repressor. When a recombinant protein has low toxicity and high yield is desired, cell strains with lower level of lacI should be used. Our special media  are sufficient to express most low toxic proteins. For extremely toxic protein, high lacI expressing cell strains, different vectors and protocol may be used. Plasmids generated from pBR322 or pUC19 all have ColE1 replication origins. pACYC plasmids are generated from pACYC177 and pACYC184 plasmids. All above cell strains are compatible with plasmids generated from replication origins other than ColE1 and pACYC.
