Biological Data
Application notes
#Protocol 1: Hoechst 33342 staining of mouse brain sections.
400µm mouse brain sections were cut using a vibratome and were incubated in carbogen bubbled artificial cerebral spinal fluid (aCSF).
Sections were incubated in 1µg/ml Hoechst 33342 in aCSF for 20 minutes at 37°C before being washed for 10 minutes in aCSF.
Sections were imaged on a Leica SP8 AOBS confocal laser scanning microscope using the 405nm laser line.
