Cattanach's translocation: cytological characterization by quinacrine mustard staining.
Metaphase chromosomes of mice carrying Cattanach's translocation, which is the deletion of material from a medium-sized autosome and its insertion into an X chromosome, were stained with quinacrine mustard. Comparison of the fluorescence patterns of these chromosomes with those of the chromosomes of normal mice has allowed the identification of the autosome involved in the translocation and loc...
متن کاملChromosome variation within Drosophila simulans detected by quinacrine staining.
HEN stained with quinacrine o r nitrogen mustard derivatives of quinacrine, certain regions of Drosophila salivary gland chromosomes fluoresce with extraordinary brilliance (VOSA 1970; ELLISON and BARR 1971). Although the biochemical specificity of this reaction is not well understood, the method of quinacrine staining can be used for cytological comparisons of chromosomes among species and wit...
متن کاملDifferential characterization of holocentric chromosomes in triatomines (Heteroptera, Triatominae) using different staining techniques and fluorescent in situ hybridization.
A comparative study of holocentric chromosomes in the triatomine species Panstrongylus megistus, Rhodnius pallescens and Triatoma infestans was carried out in order to characterize heterochromatin, rDNA active sites and nucleolar proteins. Cytological preparations of seminiferous tubules were stained by silver impregnation, C banding, fluorochromes cma3/da and dapi/da, and fluorescent in situ h...
متن کاملApplication of Fluorescent Staining of Chromosomes to Genetic Studies in Citrus
The application of staining with the guanine-cytosine specific fluorochrome chromomycin A3 (CMA) of citrus chromosomes to genetic studies is reviewed. When CMA staining is performed, the existence of characteristic CMA banding patterns with high levels of diversity and heterozygosity in citrus chromosomes is demonstrated. Similar CMA banding patterns have been observed in related species. Thus,...
متن کاملFluorescent staining of Histoplasma capsulatum.
In an earlier paper from this laboratory (Gordon, 1958) it was demonstrated that fluorescein-labeled specific antiserum employed as a cellular stain will differentiate Candida albicans and Candida tropicalis from other yeasts and yeastlike organisms, including the remaining members of the genus Candida. The present report describes the preparation and use of a similar reagent for detection and ...
