Measurements were made of the average size of fluorescent halos of nucleoids of developing frog embryos, mouse fibroblasts (A9 cells) and Friend erythroleukemia cells cultured with various compounds. These halos are thought to represent relaxed lengths of loops of DNA attached to the nuclear matrix. Measurement of transcription of RNA from nuclei in vitro(More)
unique solid-state optical sensor configuration has been developed that can serve as a development platform for a host of chemical and biochemical sensors in either gaseous or liquid environments. We describe the first adaptation of the device to oxygen sensing via fluorescence quenching and note the clear and distinct advantages over existing(More)
