The application of resonance light scattering (RLS) particles for high-sensitivity detection of DNA hybridization on cDNA microarrays is demonstrated. Arrays composed of approximately 2000 human genes ( ... More
The murine beta-globin locus control region regulates the rate of transcription but not the hyperacetylation of histones at the active genes.
Authors: Schübeler D; Groudine M; Bender M A;
Journal:Proc Natl Acad Sci U S A
PubMed ID:11553791
Locus control regions (LCRs) are defined by their ability to confer high-level tissue-specific expression to linked genes in transgenic assays. Previously, we reported that, at its native site, the murine beta-globin LCR is required for high-level beta-globin gene expression, but is not required to initiate an open chromatin conformation of ...
