Can I use frozen PBMCs instead of CD14⁺ monocytes to generate dendritic cells with PromoCell DC Generation Medium?
No. Frozen PBMCs are not suitable as starting material for dendritic cell (DC) generation using PromoCell DC Generation Medium (C-28050).
Peripheral blood mononuclear cells (PBMCs) consist mainly of lymphocytes and monocytes. During cryopreservation, CD14⁺ monocytes significantly lose their ability to attach to tissue culture plastic. As a result, the monocyte purification step using Monocyte Attachment Medium does not work with frozen PBMCs.

You can generate dendritic cells by starting with:

- Freshly isolated mononuclear cells, or
- Fresh CD14⁺ monocytes
