Abstract
This protocol has been developed for dissociation of adult mouse kidney into a single cell suspension. We have verified that all major epithelial cell types are present in the dissociated cells, and the resulting suspension is suitable for use in either FACS analysis or single cell RNA sequencing applications. The presence of interstitial cell types has not yet been validated but this protocol will be updated when those results are available.

Procedure
- Anesthetize mice with isoflurane
- Perfuse heart with cold PBS
- Take out kidney and start processing, or store in ‘Tissue collecting buffer’ on ice until ready to continue
- Remove kidney capsule, and mince kidney into small pieces of 1-2mm
- Put minced kidney in C-tube (for gentleMACS dissociater)
- Add 2 mL Librase enzyme solution to C-tube per kidney
- Run D-01 program on gentleMACS dissociater*
- Incubate sample for 10 minutes at 37°C under continuous rotation *
- Run D-01 program on gentleMACS dissociater*
- Add 4 mL of DMEM/F12 with 10% FBS
- Spin 5 min at 800 rcf at 4°C
- Wash the cells with ice-cold PBS
- Spin 5 min at 800 rcf at 4°C
- Lyse the red blood cell with 1 mL RBC lysis buffer, incubate for 5 min at RT
- Spin 5 min at 800 rcf at 4°C
- Resuspend the pellet in 2 mL 0.5% Trypsin
- Incubate sample for 10 minutes at 37°C under continuous rotation *
- Run D-01 program on gentleMACS dissociater*
- Add 4 mL of DMEM/F12 with 10% FBS
- Filter through 40 μm cell strainer.
- Spin 5 min at 800 rcf at 4°C
- Wash with ice-cold PBS and pellet the cells at 800 rcf for 5min
- Resuspend the cells in ice-cold PBS and assess cell viability by Trypan blue staining
- Longer incubation with enzyme needs less mechanical dissociation with gentleMACS. This will results in better cell viability, so one could play around with conditions here.
