Notes
ABIN3058918 successfully labels SOD-1 in lysates of equine fibroblast and human SH-SY5Y cells.
Validation Images
Total protein lysates from horse fibroblasts and human SH-SY5Y cells were separated were separated on a polyacrylamide gel under denaturing conditions. SOD-1 and TUBB protein bands were revealed as described in the protocol section.
Seed 2x105 horse fibroblasts in a T25 flask and grow for 48h at 5% CO2 in supplemented with Dulbecco’s modified Eagle media (Sigma-Aldrich, D5546), with 10% heat-inactivated fetal calf serum (FCS) and 2mM (1%) L-glutamine and 1% penicillin (10IU/ml)/streptomycin (100µg/ml) to form a monolayer of 70-90%.
Human SH-SY5Y are cultured in identical conditions.
Wash cells once ice cold PBS.
Add 500µl chilled RIPA buffer (50mM Tris pH 7.5, 150mM NaCl, 1% NP40, 0.5% Na-deoxychlorate, 0.5% SDS, 1mM EDTA, 1mM EGTA, 1mM PMSF and 1x protease inhibitor) to each flask and incubate for 1min on ice.
Scrape each monolayer and transfer protein aggregates to a separate 1.5ml microcentrifuge tube.
Incubate for 20min on ice.
Centrifuge at 14000rpm for 20min at 4°C.
Remove the supernatant and determine the concentration of soluble proteins against a BSA protein standard using a DC protein assay (Biorad, 5000112).
Adjust protein samples to 0.3mg/ml total protein, using RIPA buffer and loading buffer.
After boiling for 5-10min, 1-10µg of each sample is separated on an Any kD Mini-PROTEAN TGX Stain-Free Precast Gel (Biorad, 4568123) at 100V for 90min.
Transfer proteins onto a PVDF blotting membrane (Hybond P, GE Healthcare Life Sciences, RPN303D) for 90min at 300mA.
Block the membrane with PBST containing 10% dry milk for 1h at RT.
Incubation with primary SOD-1 antibody (antibodies-online, ABIN3058918) diluted 1:1000 and a TUBB loading control antibody (abcam, ab6046) diluted 1:1000 in PBST containing 5% dry milk ON at 4°C.
Wash 5 times with PBST over 1 hour whilst shaking.
Incubation with secondary goat anti-rabbit-IgG horseradish peroxidase-linked whole antibody (Dako, D0487) diluted 1:5000 in PBST for 1h at RT.
Wash 5 times with PBST over 1 hour whilst shaking.
Blots were developed with Amersham ECL Prime Western Blotting Detection reagent (GE Healthcare Life Sciences, RPN2232) and visualized on a Kodak developer.
Experimental Notes
The same human cell lysates were also used for a different blot with an anti-human SOD-1 antibody (lab stock). A band of the same molecular weight as in the horse fibroblast lysates was revealed.

Notes
ABIN3058918 achieves SOD-1 staining in horse fibroblasts when grown in a monolayer.
Validation Images
Horse fibroblasts were grown in a monolayer and stained with ABIN3058918 (red) as desecribed in the protocol. DAPI (blue) was used to visualize nuclei.
Full Methods
Primary Antibody
ABIN3058918
Secondary Antibody
anti-rabbit labeled with Alexa Fluor 594
Full Protocol
Horse fibroblasts are seeded onto glass coverslips pre-treated with 1:10 diluted Matrigel (BD Biosciences, 354234) at a density of 1x105 cells per coverslip in a 24 well plate.
Incubate for 48h at 37°C in 5% CO2.
Wash coverslips with PBS.
Fix coverslips with 4% paraformaldehyde (PFA) and 0.1% triton for 20min at 4°C, followed by 8% PFA for 30min at RT.
Permeabilize cells with 0.5% triton for 30min at RT.
Wash coverslips 3 times with PBS.
Incubate coverslips with primary rabbit anti SOD-1 antibody (antibodies-online, ABIN3058918) diluted 1:40 in a dark, humidified chamber for 1h at RT. A negative control was incubated without primary antibody.
Wash coverslips 3 times with PBS.
Incubate with secondary goat anti rabbit labeled with Alexa Fluor 594 (ThermoFisher Scientific, A10239) diluted 1:500 for 1h at RT.
Wash coverslips 3 times with PBS.
Mount coverslips in a hard setting mount with VECTASHIELD HardSet Antifade Mounting Medium with DAPI (Vector Laboratories, H-1500).
Fluorescence microscopy is then used to image each coverslip.
