Internal and Flanking Sequence from AFLP Fragments Using Ligation-Mediated Suppression PCR

Internal and flanking sequence from AFLP fragments using ligation-mediated suppression PCR.

Amplification fragment-length polymorphism (AFLP) analysis has proven to be a powerful tool for developing a large number of reliable genetic markers across a wide variety of organisms. Often it is desirable to further characterize these markers by obtaining internal and flanking sequence information. Here, we present a systematic approach for obtaining such information from AFLP markers. AFLP ...

Ligation-mediated PCR amplification of specific fragments from a class-II restriction endonuclease total digest.

A method is described which permits the ligation- mediated PCR amplification of specific fragments from a Class-II restriction endonuclease total digest. Feasibility was tested using Bcl I and phage lambda DNA as a model enzyme and amplicon system, respectively. Bcl I is one of many widely used restriction enzymes which cleave at palindromic recognition sequences and leave 5'-protruding ends of...

In vivo footprinting using UV light and ligation-mediated PCR.

Analysis of microRNA signatures using size-coded ligation-mediated PCR

The expression pattern and regulatory functions of microRNAs (miRNAs) are intensively investigated in various tissues, cell types and disorders. Differential miRNA expression signatures have been revealed in healthy and unhealthy tissues using high-throughput profiling methods. For further analyses of miRNA signatures in biological samples, we describe here a simple and efficient method to dete...

PCR- and ligation-mediated synthesis of marker cassettes with long flanking homology regions for gene disruption in Saccharomyces cerevisiae.

We developed a novel method for synthesizing marker-disrupted alleles of yeast genes. The first step is PCR amplification of two sequences located upstream and downstream of the reading frame to be disrupted. Due to the addition of non-specific single A overhangs by Taq DNA polymerase, each PCR product can be ligated with a marker DNA which has T residues at its 3' ends. After amplification of ...
