Plant DNA flow cytometry and estimation of nuclear genome size.
BACKGROUND DNA flow cytometry describes the use of flow cytometry for estimation of DNA quantity in cell nuclei. The method involves preparation of aqueous suspensions of intact nuclei whose DNA is stained using a DNA fluorochrome. The nuclei are classified according to their relative fluorescence intensity or DNA content. Because the sample preparation and analysis is convenient and rapid, DNA...
متن کاملGenome size and ploidy of Paracoccidioides brasiliensis reveals a haploid DNA content: flow cytometry and GP43 sequence analysis.
The aim of this study was to evaluate genome size and ploidy of the dimorphic pathogenic fungus Paracoccidioides brasiliensis. The cell cycle analysis of 10 P. brasiliensis isolates by flow cytometry (FCM) revealed a genome size ranging from 26.3+/-0.1Mb (26.9+/-0.1fg) to 35.5+/-0.2Mb (36.3+/-0.2fg) per uninucleated yeast cell. The DNA content of conidia from P. brasiliensis ATCC 60855-30.2+/-0...
متن کاملFlow Cytometry
Flow cytometry is a technology that has impacted both basic cell biology and clinical medicine in a very significant manner. The essential principle of flow cytometry is that single particles suspended within a stream of liquid are interrogated individually in a very short time as they pass through a light source focused at a very small region. The optical signals generated are mostly spectral ...
متن کاملFlow Cytometry
Because it has been difficult to identify and separate malignant cells in human lymphoid malignancies, we have developed a flow cytometry-based fluorescent in situ hybridization (FISH) technique using immunoglobulin (Ig) heavy chain variable region (V H) gene probes. After obtaining the specific V H gene sequence expressed by the multiple myeloma IM-9 cell line and the malignant cells in five m...
متن کاملAnthocyanin inhibits propidium iodide DNA fluorescence in Euphorbia pulcherrima: implications for genome size variation and flow cytometry.
BACKGROUND Measuring genome size by flow cytometry assumes direct proportionality between nuclear DNA staining and DNA amount. By 1997 it was recognized that secondary metabolites may affect DNA staining, thereby causing inaccuracy. Here experiments are reported with poinsettia (Euphorbia pulcherrima) with green leaves and red bracts rich in phenolics. METHODS DNA content was estimated as flu...
