Crystal Violet Assay for Determining Viability of Cultured Cells. We use cookies to improve your website experience. Activity decreases with storage, even frozen. is it alright to use the culture media (with serum) because to show how the cells adhere to the substrate? It depends- are you trying to look at the influence of serum on the cell attachment? 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.
