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.

Carbohydrate engineering of the recognition motifs in streptococcal co‐aggregation receptor polysaccharides

TL;DR: The genes for the glycosyltransferases that synthesize GalNAcβ1‐3GalNAc or Galβ1-3Gal recognition motifs were identified by high‐resolution nuclear magnetic resonance (NMR) analysis of genetically altered polysaccharides to provide further insight into the structural basis of RPS function.

Glycosylated yellow laccases of the basidiomycete Stropharia aeruginosa.

TL;DR: Biochemical characterisation of two yellow laccases, Yel1p and Yel3p, show that they are both secreted, monomeric, N-glycosylated proteins of molecular weight around 55kDa with substrate specificities typical of laccased proteins, but lacking the absorption band at 612nm typical of the blue laccase proteins.

Whole-Genome Sequence Analysis and Genome-Wide Virulence Gene Identification of Riemerella anatipestifer Strain Yb2

TL;DR: This genome-wide study identified genes important to the virulence of R. anatipestifer strain Yb2 and identified 49 virulence genes that are associated with metabolism, cellular processing and signaling, and the functions of the other 23 genes are poorly characterized or unknown.

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.
