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.

Isolation and characterization of a rolling-circle-type plasmid from Rhodococcus erythropolis and application of the plasmid to multiple-recombinant-protein expression.

TL;DR: This result indicates that pRE8424 belongs to the pIJ101/pJV1 family of rolling-circle-replication plasmids, which are suitable for the simultaneous expression of multiple recombinant proteins.

Differential stress induction of individual Alu loci: implications for transcription and retrotransposition.

TL;DR: In this paper, the 3′ flanking sequences for several transcriptionally active human Alu elements were identified by cDNA cloning and used for primer extension analysis to compare the basal and stress-induced expression of the corresponding Alu loci.

Overexpression of PGA37/MYB118 and MYB115 promotes vegetative-to-embryonic transition in Arabidopsis.

TL;DR: Results suggest that PGA37/MYB118 and MYB115 promote vegetative-to-embryonic transition, through a signaling pathway independent of WUS, and an elevated LEC1 expression level.

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.
