Whole-mount Immunofluorescence Imaging: A Fixing and Staining Technique to Evaluate Intact Organoids
Overview
This video describes the technique of immunofluorescent staining of intact prostate cancer organoids and their imaging by whole-mount confocal microscopy. This technique aims to evaluate the ex vivo differentiation capacity of basal and luminal prostate epithelial cells.
Protocol
1. Fixing and Staining Prostate Organoids for Immunohistochemical Analysis by Whole-mount Confocal Microscopy
- Collecting prostate organoids from 24-well plates — TIMING: 45-60 min
NOTE: When collecting prostate organoids to process for confocal microscopy, it is critical to handle them with care in order to maintain their structure. The collection protocol below is designed to reduce disruption of the organoid structure during isolation.- Rem.......
