    One Shot® BL21(DE3) Chemically Competent E. coli are ideal for use with bacteriophage T7 promoter-based expression systems (e.g., pRSET, pCR™T7, and pET).Ttight regulation of expression is conferred due to the presence of lacI q repressor encoded by the F episome.Forum Bl21 de3 invitrogen

    Users have reported difficulties using Invitrogen cuvettes (Cat.# ). Optional transformation control reactions include electroporation with 1 µL (10 pg).A mixture of 1 ml GluRS lysate to 15 ml empty-vector lysate was chosen so that GluRS would be present at a very low concentration relative to host proteins see lysate load [L] lanes in Fig.

    Furthermore, we speculated that mutants would be easy to identify as fluorescent secondary colonies, so-called papillae, outgrowing from the initially established colonies.

    However, we have not followed this as a general approach, since we expect that many proteins would not tolerate removal of multiple histidines.
