For analysis of metaphase chromosomes, any tissue containing dividing cells can be used: Root tips from young seedlings, from newly grown roots at the edge of plant pots or hydroponic culture are all suitable. Alternatively, flower buds, anthers, carpels or leaf or apical meristems can be used. Includes metaphase arresting reagents. - [Read Accumulation and Fixation of Plant Metaphase Chromosomes Protocol]

FIXATION and DNA Staining for Cell Cycle Analysis Protocol. This method of DNA staining utilizes ethanol to fix the cells and permeabilize the membrane, which allows the dye (Propidium Iodide) to enter the cells. Propidium Iodide (PI) is a DNA-binding fluorochrome that intercalates in the double-helix. Ribonuclease-A is used to eliminate the staining of double-stranded RNA. - [Read FIXATION and DNA Staining for Cell Cycle Analysis]
Fixation is to preserve cells and tissue constituents in as close a life-like state as possible and to allow them to undergo further preparative procedures without change. Fixation arrests autolysis and bacterial decomposition and stabilises the cellular and tissue constituents so that they withstand the subsequent stages of tissue processing. Great detailed guide with protocols. Anthony S-Y Leong. - [Read Fixation and Fixatives - A great guide]
Protocol for fixation and permeabilization of C. elegans. Protocol works for all stages except dauers (which won't open) and hypoclorite-treated eggs (which disintegrate). Luckily, hypochlorite treatment and fixation are by themselves sufficient to open eggs. - [Read Fixation and Permeabilization of C. elegans Protocol]
Paraffin Embedding Protocol for molecular profiling. This Paraffin Embedding Protocol describes the processing of the tissues into sections following ethanol fixation. Molecular profiling (MP) is a technique that is used to visualize the global patterns of RNA expression or protein expression in various cell types and disease processes.
