Population studies involve the analysis of attachment events for a group of cells. The incubation time chosen for attachment assay depends on the cell type, as some cells adhere more quickly than others, but 15-20 min is usually adequate. Cell attachment studies include the analysis from the formation of a molecular bond between the cell surface receptors and the complementary ligands (on the surface of ECM) to the observation of a population of cell responses through the cell behavior and changes of morphology during the attachment events.

Invert plate and shake out BSA blocking solution. 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.
