The polymerase chain reaction (PCR)-based mRNA differential display (3) has been widely used for identifying differentially expressed mRNA in a variety of biological systems (4). mRNA differential display consists of two basic steps: (i) reverse transcription (RT) using a set of 3′-anchored primers, T12MN (M = G, A or C; N = G, A, T or C) and (ii) PCR amplification of cDNA fragments using an ar...

We previously described a targeted genomic differential display method (TGDD: Broude NE, Chandra A, Smith CL. Differential display of genomic subsets containing specific interspersed repeats. Proc. Natl. Acad. Sci. USA 1997;94:4548-53). In that method, presently characterized as method I, targeting was accomplished by capturing DNA fragments containing specific a sequence by hybridization with ...

~The first two authors contributed equally to the establishment of the method and to the results obtained. 4present address: Max-Planck-Gesellschaft, MaxDelbr~ick-Haus, 13122 Berlin-Buch, Germany. Analysis of gene expression is a central aim in most studies in molecular and cell biology. Interest in tissue-specific gene expression and, in particular, in changes in the expression patterns occurr...

Establishing a microbial diagnosis for patients with community-acquired pneumonia (CAP) is still challenging and is often achieved in only 30-50% of cases. Polymerase chain reaction (PCR) has been shown to be more sensitive than conventional microbiological methods and it could help to increase the microbial yield for CAP patients. This study was designed to develop, optimize and evaluate multi...
