Application protocol
Isolation and analysis of tissue-derived
CD11c+ mouse dendritic cells
CD11c+ mouse dendritic cells
This application protocol describes the procedure to dissociate mouse spleen, lung, and intestine using the gentleMACS™ Dissociator and specific tissue dissociation kits in order to obtain viable subsets of DCs that can be further isolated using MACS® Cell Separation Technology or flow sorting.
Protocol
- Use the Spleen Tissue Dissociation Kit, mouse to generate a single-cell suspension for subsequent isolation of dendritic cells. The kit is designed to ensure high viability of CD11c+ cells and to preserve epitopes for cell isolation and staining. Follow the protocol of the kit data sheet.
- Suspend cells in PBE buffer and determine cell number.

- Use the Lung Tissue Dissociation Kit, mouse to generate a single-cell suspension for subsequent isolation of dendritic cells. The kit is tissue-specific and designed to ensure high viability of isolated cells. With preserved epitopes, the cell suspension is optimal for cell isolation and staining. Follow the protocol of the kit data sheet.
- Suspend cells in PBE buffer and determine cell number.

- Clear small intestines of feces and remove Peyer's patches.
- Remove intraepithelial lymphocytes (IELs).
- Digest remaining tissues to obtain the lamina propria lymphocytes.
- Suspend cells in PBE buffer and determine cell number.
All steps are described in detail in the protocol of the Lamina Propria Dissociation Kit, mouse.

Pan dendritic cells (DCs) are enriched from each of the dissociated tissues with CD11c MicroBeads, UltraPure, mouse. The isolated tissue-derived DCs show specific surface markers that enable the detailed analysis of distinct DC subsets.
- Follow the protocol of the data sheet for the CD11c MicroBeads UltraPure, mouse, to isolate the CD11c+ dendritic cells for each of the cell suspensions. The negative flow-through fraction is discarded and the positive fraction contains the CD11c+ to be analyzed by flow cytometry.
- Stain the isolated CD11c+ in PBE buffer for 10 minutes at 4 °C with the respective antibodies listed in the table below.
- Perform flow cytometry on the MACSQuant® Analyzer 10 and analyze data with Flowlogic™ V7.

PBE buffer for spleen/lung tissue dissociation and for cell isolation
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).
▲ Note: Always use freshly prepared buffer. Do not use autoMACS Running Buffer or MACSQuant® Running Buffer as they contain a small amount of sodium azide that could affect the results.
