CCP4bb navigationCCP4bb <-- 1999 <-- November 1999 <-- 30 November 1999Subject: Semet in non-auxotrophic strains From: Jacob Keller j-keller2 {- at -} MD {- dot -} NORTHWESTERN {- dot -} EDU Date: 2008-11-03 Dear Crystallographers, I have been using an E coli strain called Tuner (DE3) pLacI, which is not auxotrophic for methionine, nor is there an auxotrophic analogue available. It may be that my protein can be expressed in other strains, but this one works well right now, and it is usually better to stay with what works well. Has anybody tried growing semet protein in non-auxotrophic strains, or are there tricks to using non-auxotrophs for semet protein? Thanks, Jacob ******************************************* Jacob Pearson Keller Northwestern University Medical Scientist Training Program Dallos Laboratory F.
