Cell attachement occuring after 48 hours, not 24 hours.

I was told that the primary cells went through a rough time during their isolation. They were treated with water instead of pbs by mistake and the sorted cells took a long time to grow.

After 48 hours most of the cells are attached, there are still a couple of cells floating but not as many as before.
After 72 hours, 99.9% of the cells are attached with barely any floaters.

The standard ways to test for mycoplasma contamination are: staining with Hoescht 33258 and looking for extranuclear or extra cellular blue dots (quite small) with a fluorescence microscope, and growing in a soft agar assay. You will not readily see mucoplasma with an ordinary light microscope unless you have a very heavy contamination and some luck. They do not look like ordinary bacteria as they don't have a cell wall and are largely intracellular.
