TLDR
The feasibility of IPCR is shown by amplifying the sequences that flank an IS1 element in the genome of a natural isolate of Escherichia coli.
Abstract
A method is presented for the rapid in vitro amplification of DNA sequences that flank a region of known sequence. The method uses the polymerase chain reaction (PCR), but it has the primers oriented in the reverse direction of the usual orientation. The template for the reverse primers is a restriction fragment that has been ligated upon itself to form a circle. This procedure of inverse PCR (IPCR) has many applications in molecular genetics, for example, the amplification and identification of sequences flanking transposable elements. In this paper we show the feasibility of IPCR by amplifying the sequences that flank an IS1 element in the genome of a natural isolate of Escherichia coli.

Using TRIP for genome-wide position effect analysis in cultured cells.

TL;DR: A detailed protocol for analyzing thousands of reporters integrated in parallel (TRIP) at a genome-wide level and offering a 100–1,000-fold higher throughput in a faster and less-labor-intensive manner is provided.

Evidence for horizontal transfer of SsuDAT1I restriction-modification genes to the Streptococcus suis genome.

TL;DR: Different strains of Streptococcus suis serotypes 1 and 2 isolated from pigs either contained a restriction-modification (R-M) system or lacked it, and results suggest that the SsuDAT1I system could have been integrated into the S. suis chromosome by an illegitimate recombination mechanism.

Origin of Pax and Six gene families in sponges: Single PaxB and Six1/2 orthologs in Chalinula loosanoffi.

TL;DR: The phylogeny of Pax and Six genes is analyzed and a model of the evolution of the Pax gene subfam families in metazoans is derived, illustrating a diversification of Pax genes into subfamilies mostly in triploblasts before the protostome-deuterostome split, whereas few subfam Families were lost in various phyla after the Cambrian explosion.

Calling cards for DNA-binding proteins.

TL;DR: This work constructed customized calling cards for seven transcription factors of yeast by including in each Ty5 a unique DNA sequence that serves as a "molecular bar code" that reveals the transcription factors that visited that region of the genome.

Enzymatic amplification of beta-globin genomic sequences and restriction site analysis for diagnosis of sickle cell anemia.

TL;DR: Two new methods were used to establish a rapid and highly sensitive prenatal diagnostic test for sickle cell anemia, using primer-mediated enzymatic amplification of specific beta-globin target sequences in genomic DNA, resulting in the exponential increase of target DNA copies.

Specific synthesis of DNA in vitro via a polymerase-catalyzed chain reaction.

TL;DR: A method whereby a nucleic acid sequence can be exponentially amplified in vitro is described in the chapter, and the possibility of utilizing a heat-stable DNA polymerase is explored so as to avoid the need for addition of new enzyme after each cycle of thermal denaturation.

DNA typing from single hairs

TL;DR: Three different means of DNA typing are used for the determination of amplified DNA fragment length differences, hybridization with allele-specific oligonucleotide probes, and direct DNA sequencing on single human hairs to detect genetically variable mitochondrial and nuclear DNA sequences.
