WebThen, the medium was removed, the cells were washed with PBS and then fixed with 4% paraformaldehyde for 15 min. Following removal of the fixing agent, the cells were stained with 0.5% crystal violet in aqueous 25% methanol for 10 min and washed with distilled water, and morphological images were obtained with a scanner. WebFixation by alcohols works by removing the hydrate cover, causing the proteins to collapse and re-fold in the process, rendering them insoluble. Methanol is merely the fastest …

WebOct 1, 2000 · The stained cells were analyzed by flow cytometry. Results: The fixation of cells with a mixture of 0.25% paraformaldehyde and 70% methanol, permeabilization with 0.05% Triton X-100, and increasing antibody and antigen reaction time led to 80-99% of cells being stained with anti-ER antibodies. The relative brightness of ER … WebTypically, cells belong locked with formaldehyde to fix the cell membrane, and then permeabilized over laundry or alcohol to allow antibodies against intracellular chemical access to stain intracellularly.
