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]
Paraformaldehyde Fixation of Cells protocol. This fixation method is good for cells labeled by fluorochrome-conjugated antibodies to membrane antigens. It will stabilize the light scatter and labeling for up to a week in most instances, allowing you to be more flexible in scheduling cytometer time. Furthermore, it inactivates most biohazardous agents, so it is important from a safety standpoint as well. Iowa University. - [Read Paraformaldehyde Fixation of Cells]

Protocol for Protein Extraction Using Proteomics. Extraction of proteins from plant cells that are rich in compounds that interfere with the 2-Dimensional electrophoretic separation methods such as salts, organic acids, phenolics, pigments, terpenes, among others. A common protocol used in our lab for extraction proteins from plant tissues consists in the homogenization of mortar-grounded material in liquid nitrogen with an extraction buffer. - [Read Protocol for Protein Extraction Using Proteomics]
