Is it possible to carry out the macrophage differentiation in either a 96- or 384-well plate, so long as the volumes are adjusted accordingly? If not, is it possible for cells to be detached and re-plated in the desired culture plate?

a) We usually perform macrophage differentiation in T75 flasks and 6-well plates. We haven't tested differentiation in smaller formats. But we assume it will be problematic to thoroughly wash the surface of the wells to remove non-adherent cells after the attachment phase. b) Detachment of the mature macrophages is possible but re-attachment can lead to significant cell loss (30-50%). Please also keep in mind that working in 96/384 well-format has some inherent drawbacks (e.g., evaporation of media, dry wells, etc.).
