The LEXSinduce Expression Kits yielded the highest expression levels of target proteins obtained so far. Protein expression in the engineered LEXSY host T7-TR is efficiently regulated by the well-known T7 RNA polymerase/TET repressor architecture. High-level transcription is induced by addition of Tetracycline to the growth medium. Selection is performed with the antibiotic LEXSY Neo or LEXSY Bleo. Expression vectors with both alternative markers can be introduced into the same cell for coexpression of two proteins.

The 3rd generation of inducible LEXSY now allows convenient co-expression of the protein of interest with BleCherry conferring both, antibiotic resistance for selection with the antibiotic LEXSY Bleo as well as visible fluorescence under daylight as a direct read out for protein production. In addition, the new pLEXSY_I-3 vector generation has been reduced in size by about 1 kb compared to the 2nd generation vectors which allows easier cloning of large target genes (> 5 kbp) for expression.

All vectors are available separately. Links to their maps and sequences, are found in the
