Mouse brain tissue was harvested and placed in ice cold PBS (Fisher,
BP2438). Brains were sliced into 300 μM sections on a vibratome. Two mm punches were taken from each section. Punches from the left side were put into
RNAlater (Sigma, R0901) for mRNA quantification.
NHP brains were perfused with ice-cold PBS (Fisher,
BP2438) prior to sectioning. Brains were sectioned in a brain matrix into 4 mm sections. 2 mm punches were taken from various brain regions and placed in
RNAlater (Sigma, R0901) for mRNA quantification.
As described previously
16 (link), tissues were lysed in
Quantigene 2.0 homogenizing buffer (Invitrogen, QG0517) with
proteinase K (invitrogen, 25530–049). mRNA was detected according to the Quantigene 2.0 protocol using the following probe sets: mouse HTT (SB-14150), mouse GFAP (SB-14051), mouse IBA1 (SB-3027744), mouse HPRT (SB-15463), mouse PPIB (SB-10002), mouse
ApoE (SB-13611), NHP HTT (SF-10209), NHP GFAP (SF-4228397), NHP IBA-1 (SF-4214274), and NHP HPRT (SF-10356).
