Hi Paul,
Here is the answer -

Q1: We do not have experience with stem cells. I would suggest you to monitor the color development anytime from 6h to 48h (or even longer) incubation, until you see blue colored cells.

Q2: Residual fixative (PFA) might affect staining and reproducibility. I would suggest to wash at least twice before proceed. However, I would suggest to coat dishes/slides with different reagents (fibronectin, collagen, or gelatin) to reduce detachment of the cells.

Hope this helps.
