Abstract:
Transcardiac perfusion with saline followed by 4% paraformaldehyde (PFA) is widely used to clear blood and preserve brain for immunostaining or in situ hybridization. PFA breaks into formaldehyde in solution, which cross-link protein and DNA molecules to preserve tissue and cell structure. Here we provide a step by step guide for performing this procedure in mouse.
