Oligonucleotides with LNA and targeting of biologically important RNAs
Peter Guterstam and Ülo Langel, Stockholm University, Dep of Neurochemistry,
Activity of RNA-targeting antisense oligonucleotides increases when introducing LNA monomers, implying that an 18 nucleotides long LNA/2OMe mixmer splice-switching oligonucleotide can be shortened to 12mer and have similar activity and specificity as an 18mer 2OMe oligonucleoyide. Positioning of LNA monomers has to be carefully considered when utilizing the potent LNA monomers in RNA-targeting antisense oligonucleotides.

Comparison of two different real time PCR assays and chemistry for detection of norovirus genogroup II. Method of choice?

Noroviruses (Caliciviridae) are one of the main cause of acute non-bacterial gastroenteritis in humans. Noroviruses can not be propagated in cell cultures. Thus Real Time PCR molecular methods for caliciviral detection have been recently introduced. The aim of the study was to compare two different Real Time PCR assays for detection of norovirus strains (genogroup II) and the comparison between different RT-PCR reagents and Real Time PCR instruments was made.

qPCRas a primary screen in drug discovery
GauravJaggi, Frank Boeckler, Andreas Joerger and Alan Fersht, MRC -CPE,
We report the use of qPCR technique to follow the thermal unfolding of proteins by the binding of the dye SYPRO Orange, and exploit its potential as a robust and high-throughput primary screen for small molecule drug discovery.

Efficient downregulation of the lung liquid clearing gammaENaC subunit by RNAi
Nihal Yueksekdag, Marei Drechsel, Christa Schmidt, and Josef Rosenecker, Childrens Hospital,
CF is caused by mutations in the gene encoding for CFTR. CFTR functions as chloride channel on the apical membrane of epithelia thereby regulating the transport of chloride and also sodium ions indirectly. It seems that the regulation of ENaC fails due to the mutated CFTR protein. And it is assumed that ENaC plays a role in the pathogenesis of chronic lung disease in CF-patients.

Improving the efficiency of 384 "mini-tube" technology using mosquito nanlolitre pipetting

384-well plate “mini-tube” consumables have been developed by automation companies such as REMP and The Automation Partnership (TAP) to hold compound samples divided into single-use storage tubes. Each tube holds 40 -75 µL, and is filled, sealed, stored and then thawed just once before use. However, when accessed by conventional pipetting technology, the tube’s practical working volume is as little as 20 µL, which means high compound wastage. The seal must also be pierced prior to pipetting to p

How to Perform High Throughput siRNA Transfection
Mark Hewitson, Hanno Hermann and Neil Benn, CyBio, Cenix BioScience GmbH,,
We demonstrate the optimization of siRNA transfection process for time and costs in a high throughput application with two independent measurements of the RNAi effect: The visual monitoring of Eg5 expression and the quantitative PCR measurement of GAPDH mRNA after transfection of Hela cells. The results show, that 1 wash cycle is sufficient for the removal of any remnants of the transfection complex from disposable tips, making the tips re-usable.
