Fixing cells with methanol

WebJul 1, 2024 · The PC1 scores plots for methanol, methanol:ethanol and ethanol based fixation methods still show relatively clear cells, but with the majority of the intense regions associated with the nucleoli and, to a certain extent, the rest of the nucleus while the cytoplasm is comparatively weak. WebCells are immobilized on a solid support that is optically suitable for microscopy, and then fixed. When coupled with antibody-based immunofluorescent or immunocytochemical methods, the expression of specific proteins can be quantified and localized.
