Using two-step-PCR screening which consists of direct and priority-based PCR and inverse PCR, fungal gene-deletion mutants were selected quickly and accurately. He then formulated the idea of the ligand interaction scan (LIScan), a general method that enables the engineering of “regulatable” proteins, using insertion mutagenesis. The parent template is removed using a methylation-dependent endonuclease(i.e. Int J Mol Sci. 2. For inverse PCR of the junction fragment, genomic DNA (2.5 μg) was digested withBamHI and restriction fragments ranging in size from 1.5 kb to 3.0 kb were gel purified. 3. PCR is a technique in which the DNA is amplified using a set of the sequence-specific complementary primers in the enzymatic cyclic temperature dependent reaction. For deletion or insertions of >50 bp, inverse PCR is the most popular approach. Design your primers: Design inverse primers that overlap each other by 15 bp at their 5' ends and incorporate your desired deletion, substitution, or addition. To identify precisely the location of the proximal and distal deletion breakpoints, the inverse PCR technique5 was used to isolate the 2.1 kb BamHI junction fragment for nucleotide sequence analysis.

Inverse polymerase chain reaction mutagenesis (IPCRM) has proven to be a rapid and convenient method for mu-tating cloned DNA, by simultaneously introducing a defined deletion and a unique restriction site (4). These manipulations are usually performed using “cut and paste” techniques, combined with PCR. Not affiliated  |  The Inverse-PCR is a method that allows to amplify unknown regions of DNA, starting from the flanking known region on which are positioned the primers, in inverse direction compared to a normal PCR. The primers used are 5’-phosphorylated to allow ligation of the amplicon ends after PCR. Plasmids are isolated from the resulting colonies, and screened for the desired modification. Conventional PCR requires primers complementary to both terminals of the target DNA, but Inverse PCR … Invert the Selection To invert the selected region, click Edit → Invert Selection.  |  BioTechniques 13, 214–220.
