Genes can be cloned into plasmid v...

We present a protocol for effi cient amplifi cation of a large number of DNA targets using a single-tube polymerase chain reaction (PCR) based on PCR suppression. This method allows amplifi cation of each DNA target with only one target-specifi c primer whereas the other primer is common for all targets. Thus, this approach requires n+1 primers for n targets instead of 2n in conventional PCR an...

I n the last few years, molecular hybridization methods have been used extensively in basic and applied virology because of their technical flexibility and high specificity. Using these techniques, the detection of DNA and RNA viruses directly from clinical specimens, the analysis of the specific transcriptional activity of viral genes in vitro and in vivo, and the study of virus-host relations...

The respiratory pattern generator modulates the sympathetic outflow, the strength of which is enhanced by challenges produced by hypoxia. This coupling is due to the respiratory-modulated presympathetic neurons in the rostral ventrolateral medulla (RVLM), but the underlining electrophysiological mechanisms remain unclear. For a better understanding of the neural substrates responsible for gener...

MOTIVATION We developed a technique and a tool for degenerate primer design based on multiple local alignments employing the MEME algorithm supported with electronic PCR. The objective is to find adequate primers starting from sequences with poor global similarity. We show an example of its application in our laboratory to find sequences in Brachiaria with similarity to ESTs related to apomixis.
