Engl. 41, 4402–4425(2002).10. Plates were incubated overnight at 37°C. The prime advantage of this method is its simplicity. Plasmid 66: 47–51.

NLM NIH DHHS USA.gov National Center for Biotechnology Information, U.S. The most popular mutator strain is Escherichia coli XL1-Red (Stratagene, La Jolla, CA), which lacks three of the primary DNA repair pathways, MutS, MutD and MutT, resulting in a random mutation View Article PubMed/NCBI Google Scholar 5. An aliquot (0.5 μl) of the latter was mixed with 5 μl of sample buffer, and the mixture was heated at 95°C for 3 min to denature the plasmid and to

Biol., 304, 1–9. [PubMed]17. Our target of mutagenesis with the most important restriction enzyme and primer hybridization sites is illustrated in Figure 2. Generation of the billion-member libraries requires tens of micrograms of affinity purified single-stranded template DNA.

Recently, we have introduced a new method to re-circularize the RCA product by replacing the single-cut-per-phagemid restriction digestion and self-ligation with Cre/LoxP recombination.

All seven plasmids had mutations at R164 (to H, G or C) or at D179 (to G), all of which are known to increase the ceftazidime resistance of TEM-1 β-lactamase (14,15). The template clones were sensitive to ampicillin (pie chart, white sector). Dec2013 Polishing the craft of genetic diversity creation in directed evolution.Biotechnol Adv 2013 Dec 6;31(8):1707-21. Curr.

These are known as typical mutations that improve the ceftazidime-hydrolyzing activity of the lactamase26,27. Large libraries of high mutant frequency are achieved with the described method by replacing the complex host-dependent selection for the mutated strand with the well-defined enzyme-dependent selection in primer extension mutagenesis. Effectsof Asp-179 mutations in TEMpUC19b-lactamase on susceptibilityto b-lactams. A common feature to the family B DNA polymerases, including the phi29 DNA polymerase, is that the presence of an abasic site in the template DNA is a strong stalling signal

Adv. Sequencing of these clones revealed that the two partially digested clones contained also the template sequence. In 61% of the cases,mutations consisted of the replacement of T with C, and of A with G in the complement strand.
