For the single cell study, the experiments are performed to analyze the interaction between the individual cell and the substrate, observing the morphological changes, studying the cellular migration, and measuring the traction forces. I don't think the serum will mask anything that can be shown by crystal violet, unless the attachment factors are found in serum at high concentration.Serum staving the cells before seeding is probably not a good idea, it forces the cells into G1 arrest and they may not attach from this stage (anyone who knows more about this feel free to correct me).Just remember to wash the cells well with PBS before adding the crystal violet as the serum will also stain. With multipipetter, slowly add 100 l/well of freshly diluted 1% glutaraldehyde in PBS. Salvador-Membreve DM, Jacinto SD, Rivera WL.
