Western Blot Validation of Recombinant NGF

To confirm the presence of rrβ-NGF, the dialyzed protein was subjected to TCA-acetone precipitation and then denatured in loading buffer (0.312 M Tris-HCl, 10% SDS, 25% 2-mercaptoethanol, 0.01% bromophenol blue, 50% glycerol) at 95°C. The denatured protein was then loaded on 12% SDS–PAGE gels which were run at 90 V for 2 h in duplicate. One gel was stained with Coomassie brilliant blue G-250 (Sigma Aldrich, Missouri, USA) and the other was used to transfer the protein to a nitrocellulose membrane (Ammersham Hybond ECL Nitrocellulose Membrane, GE Healthcare Life Science, Barcelona, Spain) (80 mA per membrane for 80 min). The membrane was blocked for 1 h with Odyssey blocking buffer (LI-COR Biosciences, Nebraska, USA), and then incubated at 4°C overnight with 0.1 μg/mL of goat anti-NGF antibody (N8773, Sigma-Aldrich) in blocking buffer with 0.1% Tween 20. After 6 washes, membranes were incubated at room temperature (RT) for 1 h with secondary antibody (IRDye 800CW Donkey anti-goat IgG (H + L), LI-COR Biosciences, Nebraska, USA). Finally, after additional washes, the membranes were scanned with an Odyssey fluorescence scanner (LI-COR Bioscience, Nebraska, USA).

Immunoblotting was performed as described previously (1 (link)). The following antibodies were used: anti-NRG1 β1 (R&D, AF-396-NA), anti-CD74 (Abcam, ab22604), anti-HSP90 (Cell Signaling Technology, No. 4877), anti-ERBB3 (Cell Signaling Technology, No. 4754), anti-phosphoERBB3 (Cell Signaling Technology, No. 4791), ERK1/2 (Cell Signaling Technology, No. 9102), anti-phosphoERK1/2 (Cell Signaling Technology, No. 9106), anti-AKT (Cell Signaling Technology, No. 9272), anti-phosphoAKT (Cell Signaling Technology, No. 9271), and β-actin-HRP (Santa Cruz Biotechnology, sc-47778). Secondary antibodies were IRDye800CW donkey anti-goat IgG (H+L; Licor, 925–32214), IRDye 680LT donkey anti-mouse IgG (H+L; Licor, 925–68022), and IRDye 800CW goat anti-rabbit IgG (H+L; Licor, 926–32211). Fluorescence detection was performed on Odyssey CLx Imaging System (Licor).

Cerebellar Protein Expression in Dyt1 KI Mice

Seven Dyt1 KI mice and six WT littermates of either sex at postnatal 19 days were used for Western blot analysis. The cerebellum was dissected and homogenized in 200 μl of ice-cold lysis buffer, and the proteins were extracted in 1% Triton X-100-containing buffer and quantified as previously described (Yokoi et al., 2010 (link)). Protein samples were separated on 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and transferred to Millipore Immobilon–FL transfer PVDF membranes. The PVDF membranes were blocked with LI-COR Odyssey blocking buffer and incubated at 4°C overnight with mouse anti-Slo1/BKAlpha potassium channel antibody (UC Davis/NIH NeuroMab clone L6/60; 1:4,000 dilution), rabbit anti-KCNN2 (KCa2.2, SK2) antibody (Alomone lab, APC-028; 1:4,000 dilution), and rabbit anti-glyceraldehyde-3-phosphate dehydrogenase (GAPDH) antibody (Santa Cruz, sc-25778; 1:1,000 dilution). LI-COR IRDye 800CW donkey anti-goat IgG (H+L) or LI-COR IRDye 680RD donkey anti-rabbit IgG (H+L) were used when appropriate at the dilution of 1:15,556. The infrared emission signals were detected and recorded as digital data by a LI-COR Odyssey imaging system. The density of the corresponding protein band was normalized to those of GAPDH. The western blot signals were not saturated and within the linear range. Western blot analysis was performed in duplicate.

Western Blot Analysis of Benzonase-Eluted Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
Following the described RAP-MS procedure, we saved 5% of benzonase eluted proteins for western blot analysis. We added NuPAGE LDS Sample Buffer (Thermo Fisher Scientifc) and incubated samples for 3 min incubation at 95°C. Proteins were resolved by SDS-PAGE using NuPAGE 4-12% Bis-Tris-HCl Gels (Thermo Fisher Scientific) at 200 V for 1 h, followed by transfer to a nitrocellulose membrane using the iBlot Dry Blotting System (Thermo Fisher Scientific). Western blots were performed using the iBind Western System (Thermo Fisher Scientific). For protein detection, we used the following primary antibodies: Nucleoprotein -Abcam #ab272852, POP1 -Proteintech #12029-1-AP. We used the following secondary antibodies: IRDye 800CW Goat anti-Rabbit IgG (H + L) (LI-COR), IRDye 800CW Donkey anti-Goat IgG (H + L) (LI-COR). For visualization of bands, we used the Odyssey Clx infrared imager system (LI-COR).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
