Silver staining the chromosome scaffold
Chromosoma, 1984 Cytological silver-staining procedures reveal the presence of a "core" running along the chromatid axes of isolated HeLa mitotic chromosomes. In this communication we examine the relationship between this "core" and the nonhistone chromosome scaffolding, isolated and characterized in previous publications from this laboratory.

An improved silver staining procedure for schizodeme analysis in polyacrylamide gradient gels
Memorias do Instituto Oswaldo Cruz, 1990 A simple protocol is described for the silver staining of polyacrylamide gradient gels used for the separation of restriction fragments of kinetoplast DNA [schizodeme analysis of trypanosomatids (Morel et al., 1980)]. The method overcomes the problems of

A rapid alternative technique for obtaining silver-positive patterns in chromosomes
Genetics and Molecular Biology, 2004 Silver nitrate chromosome staining to evidence nucleolar organizer regions (NORs) is a widely adopted methodology. The aim of the present work was to improve this technique, reducing the preparation time without decreasing the quality of the results ...

Investigation of the direct and indirect mechanisms of primary blast insult to the brain
Scientific Reports, 2021 The interaction of explosion-induced blast waves with the head (i.e., a direct mechanism) or with the torso (i.e., an indirect mechanism) presumably causes traumatic brain injury.

Detection of point mutations by non-isotopic single strand conformation polymorphism
Brazilian Journal of Medical and Biological Research, 1999 We have developed a procedure for nonradioactive single strand conformation polymorphism analysis and applied it to the detection of point mutations in the human tumor suppressor gene p53.

Comparative chromosome studies in species of subtribe Orchidinae (Orchidaceae) [PDF]
Comparative Cytogenetics, 2021 In our study, FISH mapping using 18S-5.8S-25S rDNA and 5S rDNA sequences was performed for the first time on Ophrys tenthredinifera Willdenow, 1805, Serapias vomeracea (Burman f., 1770) Briquet, 1910 and Himantoglossum hircinum (Linnaeus, 1753) Sprengel,
