WebJul 1, 2016 · Large-scale sequencing revealed remarkable preferences in nucleotides downstream of the amber codon, and moderate preferences for upstream nucleotides. Nucleotide preference was quantified by a dual-luciferase assay, which verified that the optimum context for NAA incorporation, AATTAGACT, was applicable to different proteins. WebBlue-White Selection / -Complementation During processes of genetic engineering, the so called Blue-White-Selection is used for evaluation of recombi-nant bacteria. Thus, it not only provides identification of those bacteria carrying the desired plasmid, but also helps to determine whether the recombination procedure has proceeded correctly.

WebIn some blue/white screening systems, an additional reagent must be used: IPTG (isopropylthiogalactoside). IPTG is an inducer that de-represses lacZ expression (it turns the gene on). In some cases, without IPTG, not enough β-galactosidase is produced to turn the colony blue even if the lacZ gene is intact. WebBlue/White Assay: pGEM®-3Zf(+) Vector is digested with representative restriction enzymes (leaving 5´-termini, 3´-termini or blunt ends). Each microgram of cut plasmid is ligated with 4 units of T4 DNA Ligase. The DNA is then transformed into JM109 cells that are plated on X-Gal/IPTG/Ampicillin plates.
