This video demonstrates the processing of lentivirus-transduced mouse intestinal organoids for paraffin embedding, to enable their downstream analysis for assessing gene expression.

プロトコル

1. Processing organoids for paraffin embedding and immunohistochemistry

1. Prior to initiation of organoid embedding, pre-warm an aluminum block with holes fitting 12 mm diameter glass tubes in incubator at 70 °C to keep paraffin liquid.

2. Take a single well with full-grown organoids and remove the medium, leaving the embedded organoids intact.

3. Add 1 ml of 4% paraformaldehyde in phosphate-buffered saline (PBS) straight to well and fix at 4 °C anywhere from 1 hr to overnight.
