Epub 2012 May 15. Trichomonas vaginalis induces cytopathic effect on human lung alveolar basal carcinoma epithelial cell line A549. The amount of Crystal Violet staining in the assay is directly proportional to the cell biomass that is attached to the plate. 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. assay cpe cytopathic interferon ifn 2022 Jun 25;14(13):3125. doi: 10.3390/cancers14133125.
