Padlock and Proximity Probes for in Situ and Array-Based Analyses: Tools for the Post-Genomic Era
نویسندگان
چکیده
Highly specific high-throughput assays will be required to take full advantage of the accumulating information about the macromolecular composition of cells and tissues, in order to characterize biological systems in health and disease. We discuss the general problem of detection specificity and present the approach our group has taken, involving the reformatting of analogue biological information to digital reporter segments of genetic information via a series of DNA ligation assays. The assays enable extensive, coordinated analyses of the numbers and locations of genes, transcripts and protein.

It is well known that cells in tissues display a large heterogeneity in gene expression due to differences in cell lineage origin and variation in the local environment at different sites in the tissue, a heterogeneity that is difficult to study by analyzing bulk RNA extracts from tissue. Recently, genome-wide transcriptome analysis technologies have enabled the analysis of this variation with ...
متن کاملParallel gene analysis with allele-specific padlock probes and tag microarrays.
Parallel, highly specific analysis methods are required to take advantage of the extensive information about DNA sequence variation and of expressed sequences. We present a scalable laboratory technique suitable to analyze numerous target sequences in multiplexed assays. Sets of padlock probes were applied to analyze single nucleotide variation directly in total genomic DNA or cDNA for parallel...

متن کاملVisualising individual sequence-specific protein-DNA interactions in situ.
Gene expression - a key feature for modulating cell fate-is regulated in part by histone modifications, which modulate accessibility of the chromatin to transcription factors. Until now, protein-DNA interactions (PDIs) have mostly been studied in bulk without retrieving spatial information from the sample or with poor sequence resolution. New tools are needed to reveal proteins interacting with...

In situ hybridization (ISH) is a method that uses labeled complementary single strand DNA or RNA to localize specific DNA or RNA sequences in an intact cell or in a fixed tissue section. The main steps of ISH consist of: probe selection, tissue or sample preparation, pre-hybridization treatment, hybridization and washing, detection and control procedure. Probe selection is one of the important ...
