Electron microscopy of synaptonemal complexes in semithin sections.

چکیده
The technique of osmium tetroxide fixation followed by a treatment with p-phenylenediamine was applied to mouse testes in order to analyze pachytene nuclei. Observation of Epon semithin sections (0.25--0.5 micrometer) in conventional electron microscopy revealed the presence of positively stained synaptonemal complexes surrounded by unstained chromatin. The present results show that by using this method a suitable contrast and resolution can be achieved for semithin sections, which facilitates the topographical study of synaptonemal complexes.

Neuroanatomy from Mesoscopic to Nanoscopic Scales: An Improved Method for the Observation of Semithin Sections by High-Resolution Scanning Electron Microscopy
Semithin sections are commonly used to examine large areas of tissue with an optical microscope, in order to locate and trim the regions that will later be studied with the electron microscope. Ideally, the observation of semithin sections would be from mesoscopic to nanoscopic scales directly, instead of using light microscopy and then electron microscopy (EM). Here we propose a method that ma...
متن کاملSerial semithin sections in immunohistochemistry: techniques and applications.
Immunostaining of semithin sections is a valuable tool in biomedical research; however, this method is rather rarely used by histologists. To overcome the apparent reservations concerning this method, the present report describes a technique which is rather simple, largely standardized, and very useful in investigative endocrinology. The technique includes the following steps: snap-freezing and...
متن کاملVisualization of identified GFP-expressing cells by light and electron microscopy.
We have developed a procedure for visualizing GFP expression in fixed tissue after embedding in LR White. We find that GFP fluorescence survives fixation in 4% paraformaldehyde/0.1% glutaraldehyde and can be visualized directly by fluorescence microscopy in unstained, 1 microm sections of LR White-embedded material. The antigenicity of the GFP is retained in these preparations, so that GFP loca...
متن کاملPostembedding immunocytochemistry of large sections of brain tissue: an improved flat embedding technique.
A method for osmicating, dehydrating, and flat-embedding large slabs of brain tissue in epoxy resin is presented. This permits the production of semithin sections for postembedding immunocytochemistry that are far larger than can be obtained with other embedding approaches. Vibratomed slabs, 50-200 microns thick and as large as 6 x 8 mm are embedded in a 'soft' Araldite epoxy. The slabs are lam...
متن کاملSynaptonemal complexes and XY behavior in two species of Argentinian armadillos: Chaetophractus villosus and Dasypus hybridus (Xenarthra, Dasypodidae).
Spermatocytes from the two armadillo species, C. villosus and D. hybridus were studied in microspreads for synaptonemal complexes (SCs) and in thin sections for electron microscopy (EM). The complete SC karyotype generally agrees with previous reports on mitotic chromosomes, except for the sex chromosomes. The X chromosome is submetacentric in both species and the Y is the shortest one in C. vi...
