Summary[edit]

Description
Eesti: Schizosaccharomyces pombe rakk duplitseeritud tsentrosoomiga. Pärmide tsentrosoomi nimetatakse ka "käävi polaarsuse kehaks" e. SPB (spindle pole body). Enne raku jagunemist paikneb SPB tuumamembraanil ning organiseerib tsütoplasmas paiknevaid mikrotorukesi. Rakkude fikseerimiseks kasutati kõrge rõhu all külmutamist. Kontrasteerimisel kasutati osmiumtetraoksiidi ja uranüülatsetaati. Pildil on näha läbilõige S. pombe rakust. Näha on rakutuum ja duplitseeritud SPB kolmel erineval suurendusel (Mõõtjoone pikkus on 500 nm). Pildid on tehtud kasutades JEOL-1220 läbivkiirguse elektronmikroskoopi.
English: Combined transmission electron microscopic images of Schizosaccharomyces pombe and its centrosome (spindle pole body). Black line represents the length of 500 nm. Image was made with JEOL-1220 in University of Tartu. Osmium tetroxide and uranyl acetate have been used as staining agents.
