I was wondering if you had any suggestions regarding the plasticware to use for monocyte enrichment/macrophage differentiation.

Usually; we do not recommend specific plasticware but we have found that with PromoCell’s Dendritic Cell and Macrophage Generation Media; choice of plasticware can have a lot of an influence. For our M1-/M2 Macrophage Generation Media XF we recommend the Nunc plasticware with Nunclon surface - as not only will the detachment efficiency vary (up to 20%); but also the efficiency of the differentiation process itself may be altered.
