High throughput and high content screening microscopy: A microscopy based guideline

Issue 4 2009, Past issues / 30 July 2009 /

The understanding of properties of any biological system requires a detailed and quantitative analysis of its parts and their interactions. As different processes within a system occur at defined space and time, each process holds its own optimal observation and investigation technique. One of the most powerful tools to analyse biological samples quantitatively is based on fluorescence microscopy. Comprehensive studies of diverse biological processes were lately performed by fluorescence screening microscopy, which came up extensively during the last decade1,2,3.

MicroRNAs for high-throughput functional analysis

Issue 3 2008, Past issues / 19 June 2008 /

MicroRNAs (miRNAs) are a class of small non-coding RNA molecules, which are potent post-transcriptional gene expression regulators. They have been shown to participate in the regulation of numerous cellular processes, the list of which is still growing. miRNAs affect numerous targets that can be determined by direct experiments or predicted by bioinformatics approaches, and are presented in several online databases. Feasibility of miRNA for high-throughput experimentation is becoming possible due to the availability of commercially produced molecules, which are able to alter the levels of endogenous miRNAs. miRNA functional analysis will help to validate predicted targets and reveal the role of these small molecules in biological pathways. miRNAs have a high potential to be used as a new gene expression regulating reagent for microscopy based assays.
