Application protocol

Generation of Mo-DCs

This application protocol describes a reliable and reproducible protocol for the generation of monocyte-derived dendritic cells (Mo-DCs). Using high-quality reagents that ensure cell viability, the resulting Mo-DCs can be used for downstream phenotypic and functional characterization.


The following is a listing of reagents, instruments, and consumables needed for each step of this protocol. These products are for research use only.

General reagent and instrument requirements

  • PBE Buffer: Prepare a solution containing phosphate-buffered saline (PBS), pH 7.2, 0.5% bovine serum albumin (BSA), and 2 mM EDTA by diluting MACS® BSA Stock Solution (# 130‑091‑376) 1:20 with autoMACS® Rinsing Solution (# 130‑091‑222). Keep buffer cold (2−8 °C). Degas buffer before use, as air bubbles could block the column.
    Note: EDTA can be replaced by other supplements such as anticoagulant citrate dextrose formula-A (ACD-A) or citrate phosphate dextrose (CPD). BSA can be replaced by other proteins such as human serum albumin, human serum, or fetal bovine serum (FBS). Buffers or media containing Ca2+ or Mg2+ are not
    recommended for use.
  • Complete medium: Prepare a medium from RPMI 1640 containing 2 mM L-glutamine and 1 % autologous plasma.
  • Phosphate-buffered saline (PBS)
  • Fetal calf serum (FCS)
  • Bovine serum albumin (BSA)
  • RPMI 1640
  • Propidium Iodide Solution (# 130-093-233) or 7-AAD for flow cytometry exclusion of dead cells
  • MACSQuant® Analyzer 10 (# 130-096-343) or similar flow cytometry analyzer plus analysis software, such as MACSQuantify™ Software (# 130-094-556)

For isolation of monocytes

  • CD14 MicroBeads, human (# 130-050-201) or CD14 MicroBeads, human – lyophilized (# 130-097-052)
  • Pre-Separation Filters, 30 μm (# 130-041-407) to remove cell clumps.
  • MACS Columns and MACS Separators: CD14+ cells can be enriched using MS, LS, or XS Columns, or positive selection can also be performed using the autoMACS Pro or the autoMACS Separator.
