Full Methods

Primary Antibody: ABIN5542704

Secondary Antibody:

HRP-conjugated goat anti-mouse IgG (Sigma-Aldrich, NA931VS)

Full Protocol:

• Homogenize tissues with cold lysis buffer containing 50 mM Tris HCl, 150 mM NaCl, 1% Triton X-100, 1 mM EDTA, and 1% protease inhibitor (Sigma P8340) using an ultrasonic homogenizer (MSE, SoniPrep 150) with 16 amplitude, 20 s on, 10 s off pulse for 60 s.
• Centrifuge tissue homogenates at 13,000 rpm for 20 min at 4 °C.
• Collect supernatants and determine total protein content using a Bradford assay.
• Denature 50 µg of total protein for 5 min at 90 °C and subsequently separate them on a denaturing 12% PAGE-SDS gel alongside a Precision Plus Protein Dual Color Standard (Bio-Rad, 160374).
• Electro-transfer proteins onto nitrocellulose membrane (Amersham Biosciences, RPN203D) ON in the cold room.
• Wash membrane 3x for 10 min with 0.01 M PBS containing 0.1% Tween-20 (PBST).
• Block membrane with PBST containing 2% bovine serum albumin for 1 h at RT.
• Incubate membrane with primary mouse anti-NeuN antibody (antibodies-online, ABIN5542704, lot 160425) diluted 1:1,000 in PBST ON at 4 °C.
• Wash membrane 3x 10 min with PBST.
• Incubate membrane with secondary HRP-conjugated goat anti-mouse IgG (Sigma-Aldrich, NA931VS) diluted 1:1,000 in PBST for 1 h at RT.
• Wash membrane 3x 10 min with PBST.
• Visualize proteins with WesternBright Sirius HRP substrate (Advansta) using a ChemiDoc Imaging System.

Experimental Notes:

Non-specific bands were also detected in adult mouse cerebellum tissue extracts, but not on laser-microdissected Purkinje neurons.

Full Methods

Primary Antibody: ABIN5542704

Secondary Antibody: anti-rabbit secondary antibody Alexa Fluor 594 (Thermo Fisher A11037, lot # 2439060)

Full Protocol:

• Perfuse mice with paraformaldehyde 4% in 0.1 M phosphate buffer pH 7.4 and post-fix of samples in the same fixative for an additional 2 h at RT.
