Experimental details: Western blot analysis was performed on Whole cell extracts (60 µg lysate) of SH-SY5Y (Lane 1) and tissue extracts of Mouse Brain (Lane 2) and Rat Brain (Lane 3). The blots were probed with Anti-Parkin Recombinant Rabbit Monoclonal Antibody (Product # 702785, 2.5 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). A 48 kDa band corresponding to Parkin was observed across the cell line and tissues tested. Known quantity of protein samples were electrophoresed using Novex®NuPAGE®4-12% Bis-Tris gel (Product # NP0322BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5% skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western blotting Substrate (Product # 32106).

Experimental details: Knockdown of Parkin was achieved by transfecting SH-SY5Y cells with Parkin specific siRNA (Silencer® select Product # s10043+s10045). Western blot analysis (Fig a) was performed using whole cell extracts from Parkin knockdown cells (Lane 3), non-specific scrambled siRNA transfected cells (Lane 2) and untransfected cells (Lane 1). The blots were probed with Anti-Parkin Recombinant Rabbit Monoclonal Antibody (Product # 702785, 1-3 µg/mL) and Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). Densitometric analysis of this Western blot is shown in histogram (Fig b). Loss of signal upon siRNA mediated knock down confirms that antibody is specific to Parkin.

Experimental details: Western blot of Parkin was performed by loading 50 µg of WT (lane 1) and PRKN CRISPR KO (lane 2) SH-SY5Y cell lysates in RIPA buffer onto a 4-15% gradient polyacrylamide gel. Proteins on the blots were visualized with Ponceau staining (below immunoblot). Proteins were transferred to nitrocellulose membrane and blocked in 5% milk for 1 hr. PRKN was detected at approximately 52 kDa using a PRKN recombinant monoclonal antibody (Product # 702785) at a dilution of 1:200 in 5% BSA in TBS with 0.1% Tween 20 (TBST) overnight at 4°C. The peroxidase-conjugated secondary antibody (Product # 65-6120) was diluted to 0.2 µg/mL in TBST with 5% milk for 1 hr. Chemiluminescent detection was performed using Pierce ECL Western Blotting Substrate (Product # 32106).

Experimental details: Western blot analysis (Fig a) of Parkin was performed on cell extracts (100 µg of lysate) of HEK-293 wild type (Lane 1) and Parkin knockout (Lane 2). The blot was probed with Anti-Parkin Recombinant Rabbit Monoclonal Antibody (Product # 702785, 1:500 dilution) and detected by chemiluminescence using Peroxidase AffiniPure Goat anti-Rabbit IgG (H+L) Secondary Antibody, HRP conjugate (Product # 111-035-144, 1:4000 dilution). Densitometric analysis of this Western blot is shown in the histogram (Fig b). Loss of signal upon CRISPR mediated knockout (KO) confirms that antibody is specific to Parkin.

Experimental details: Immunoprecipitation of PRKN was performed on SH-SY5Y cell lysates. Antibody-bead conjugates were prepared by adding 1 µg of PRKN recombinant monoclonal antibody (Product # 702785) with 30 µL of protein A-Sepharose beads and rocked overnight at 4°C. 2 mg of lysate was incubated with an antibody-bead conjugate for 2 hours at 4°C. Following centrifugation and multiple washes, 10% starting material (SM), 10% unbound fraction (UB) and immunoprecipitated fraction (IP) were processed for immunoblot using another PRKN monoclonal antibody (Product # 39-0900). Ponceau stained transfer of blot is shown. Data courtesy of YCharOS Inc., an open science company with the mission of characterizing commercially available antibodies using knockout validation.

Experimental details: Characterization of mitochondrial function and autophagy/mitophagy in hypertrophied neonatal rat cardiomyocytes (NCMs). ( a ) Ultrastructure of PBS- and Iso-treated NCMs (magnification x7000 with a scale bar of 10 um (left images) and x12,000 with a scale bar of 2 um (right images)) and quantification of mitochondria number, length (um), width (um) and area (um 2 ). Arrows indicate example of mitochondria for comparison. ( b ) Mitochondrial membrane potential was quantified in NCMs treated with Iso by fluorescence quantification of JC-1 dye for aggregates (red) and monomer (green) (from 3 independent experiments and at least 366 cells). ( c ) Representative images for quantification of Krebs cycle by Western blot of aconitase 2 and mitophagy/autophagy by Western blot of parkin, LC3II/LC3I ratio, ubiquitin and beclin-1 in NCMs treated with Iso Data were normalized to actin. ( d ) Representative images of parkin (red) and LC3 (green) localized in mitochondria (white) of untreated (PBS) and Iso-treated NCMs. Colocalization appeared in merge images. Nuclei were stained by Dapi (blue). Only significant p values are indicated from at least 3 independent experiments. Images were selected to represent the mean values of each condition.
