Ribosomal RNA Detection on Northern Blot Employing a Specific Oligonucleotide

18S ribosomal RNA detection on Northern blot employing a specific oligonucleotide.

Sensitive and specific detection of microRNAs by northern blot analysis using LNA-modified oligonucleotide probes.

We describe here a new method for highly efficient detection of microRNAs by northern blot analysis using LNA (locked nucleic acid)-modified oligonucleotides. In order to exploit the improved hybridization properties of LNA with their target RNA molecules, we designed several LNA-modified oligonucleotide probes for detection of different microRNAs in animals and plants. By modifying DNA oligonu...

Detection of microRNAs by Northern blot analyses using LNA probes.

MicroRNAs (miRNAs) are small, endogenous, non-coding RNA species, about 21 nucleotides in length, which modulate the expression of animal and plant target genes at the post-transcriptional level. It has been shown that miRNA based gene regulation plays a pivotal role in pathways involved in growth and development. Understanding miRNA mediated processes requires new technologies enabling efficie...

Simultaneous detection of Anaplasma and Ehrlichia species in ruminants and detection of Ehrlichia ruminantium in Amblyomma variegatum ticks by reverse line blot hybridization.

The detection of Anaplasma and Ehrlichia species is usually based on species-specific PCR assays, since no assay is yet available which can detect and identify these species simultaneously. To this end, we developed a reverse line blot (RLB) assay for simultaneous detection and identification of Anaplasma and Ehrlichia species in domestic ruminants and ticks. In a PCR the hypervariable V1 regio...

Homologous genes for mouse 4.5S hybRNA are found in all eukaryotes and their low molecular weight RNA transcripts intermolecularly hybridize with eukaryotic 18S ribosomal RNAs

Previous work has reported the isolation and sequencing of a mouse low molecular weight RNA species designated 4.5S hybridizing RNA or hybRNA because of its ability to intermolecularly hybridize with mouse mRNA and 18S rRNA sequences. Using synthetic DNA oligonucleotide probes we have examined the conservation of this gene sequence and its expression as a lmwRNA transcript across evolution. Sou...
