pTriEx™-4 DNA from Novagen

...E. coli is regulated by the tightly controlled T7 lac promoter. Expression can be induced in hosts such as NovaBlue by infecting with λCE6, a phage that constitutively expresses T7 RNA polymerase from the λ p L and λl p I promoters. Alternatively, pTriEx recombinant plasmids c...

X-Gal from ABgene

...nant plasmids. In the presence of X-Gal and IPTG, lac + bacterial colonies appear blue, whereas recombinant colonies appear white. Applications Blue-white selection...

LIC Duet™ Minimal Adaptor from Novagen

...C Duet™ Mini Adaptor encodes a T7 promoter, lac operator, ribosome binding site (rbs), and an ATG translation initation codon. This adaptor is designed for expression of a target protein with minimal vector-encoded fusion sequences....

LIC Duet™ T7•Tag^® Ek Adaptor from Novagen

...bull;Tag ® Ek Adaptor encodes a T7 promoter, lac operator, ribosome binding site (rbs), ATG translation initation codon, and an N-terminal T7•Tag coding sequence. The T7•Tag is a small epitope tag (11 aa) that is useful for detection of the target protein with T7•Tag Monoclonal Anti...

LIC Duet™ GST•Tag™ Ek Adaptor from Novagen

...bull;Tag™ Ek Adaptor encodes a T7 promoter, lac operator, ribosome binding site (rbs), ATG translation initation codon and an N-terminal GST•Tag coding sequence. The GST•Tag sequence has been reported to enhance the production and in some cases the solubility of its fusion partners. The...

LIC Duet™ Trx•Tag™ Ek Adaptor from Novagen

...bull;Tag™ Ek Adaptor encodes a T7 promoter, lac operator, ribosome binding site (rbs), ATG translation initation codon, and an N-terminal Trx•Tag coding sequence. The Trx•Tag is a 109 aa sequence that encodes thioredoxin. Fusion to this sequence has been demonstrated to enhance solubili...
