Adult mice were anesthetized with an overdose of pentobarbital and then transcardially perfused with 4% paraformaldehyde (PFA). Mouse brain was dissected and fixed in 4% PFA for 4 h. After cryoprotection in 30% sucrose, brain sections (35 μm) were cut on a cryostat microtome (Leica CM1950, Leica Biosystems, Wetzlar, Germany). After rinsing with PBS and 0.3% Triton-X in 0.1 M PBS (PBST), the brain sections were blocked with 2% (w/v) bovine serum (BSA) in PBST for 1 h. Then, the brain sections were incubated with primary antibodies at 4°C for 48 h and secondary antibodies at room temperature for 2 h. Images were collected using a Zeiss LSM510 Meta or Nikon A1 confocal microscope and analyzed using FIJI. The antibodies used were as follows: anti-choline acetyltransferase (1:200, goat, AB144P, MERCK, Kenilworth, NJ, United States), anti-NK1R (S8305, rabbit, 1:5,000, Sigma-Aldrich, St. Louis, MO, United States), goat anti-rabbit for NK1R (Cy3 and Alexa Fluor 488, Jackson ImmunoResearch Laboratories, Inc., West Grove, PA, United States), donkey anti-goat for choline acetyltransferase (Cy3 and Alexa Fluor 488, Jackson ImmunoResearch Laboratories, Inc., West Grove, PA, United States), and Cy3-streptavidin (1:500).

Mice were cardiac-perfused with 4% paraformaldehyde in PBS. Spinal cords were dissected and immersed in 4% paraformaldehyde in PBS overnight, washed in PBS and submerged in 30% sucrose. Tissues were embedded in O.C.T. for cryosectioning at 30 μm collected onto slides. Slides were incubated with primary antibody in 1% goat or donkey serum/0.3% Triton X-100/PBS at 4°C overnight, followed by incubation with secondary antibody conjugated with Alexa Fluor 488, 568 or 647 (Molecular Probes). For spinal cord sections subjected for BrdU staining, dsRed antibody was use along with Alexa Fluor 568 secondary to amplify the fluorescent of tdTOM. Sections were then fixed in 4% PFA/PBS for 5 minutes, treated with 2M HCl/0.2% Triton-X100 for 20 minutes to exposed BrdU epitope, then incubated with anti-BrdU overnight, followed by Alexa Fluor secondary the following day to detect BrdU+;tdTOM+ cells. All slides were mounted with Vectashield mounting medium (#101098-042) and imaged using a Zeiss LSM 510 META and Nikon ECLIPSE 80i Upright fluorescent microscopes. The following antibodies were used for this study:

After the stimulation period, cells were fixed in 4% PFA, stained for specific antigens using primary antibodies against desmin (DAKO), DDR2 (Santa Cruz), NCX (SWANT), P4HB, Vimentin, P‐CaMKII, ADAMTS13 (Abcam), incubated with fluorophore‐conjugated secondary antibodies and visualized on Zeiss LSM 510 Meta and Nikon A1 confocal microscopes. The images were analyzed using ImageJ software (ImageJ 1.46r, NIH, USA).

Visualizing Mitochondrial Morphology

After 24 hours of transfection, the cells were fixed with 4 % Paraformaldehyde in PBS. Following permeabilization with PBS containing 0.1 % Triton, 1 % BSA and 2 % Horse serum cells were incubated with anti-Myc primary monoclonal antibody (Covince; CAT#MMS-150P) overnight at 4°C. After washing the cells extensively with PBS, secondary anti-mouse FITC conjugated was added to the cells for 1h at room temperature. The staining was then visualized using a Carl Zeiss LSM510 META or a Nikon A1R confocal microscope. To quantify mitochondrial morphology, a custom ImageJ macro was utilized as previously described (9 (link)). Statistical analysis was performed using the unpaired Student's t-test and values of p<0.05 were considered significant.

Live cell imaging of eGFP-RTAE177D or eGFP-RTAE177D-HDEL was performed by confocal fluorescence microscopy using a Zeiss LSM 510 META (Nikon PlanApo 63x NA 1.4 oil immersion lens, 488 nm excitation, 1.1% argon laser power, HFT 488 and NFT 490 beam splitter, BP 500-530 filter). The same laser power and pinhole size (73 μm) were used to collect all images in each experiment.

A Zeiss LSM 510 META and a Nikon A1Rsi laser scanning confocal microscope were used for imaging. Acquired images were handled by NIS-Elements Advanced Research (Nikon), ZEN (Zeiss) and Fiji (ImageJ) (Schindelin et al., 2012 (link)). The fluorescent protein fusions used in this study are GFP-δTIP (Cutler et al., 2000 (link)), ERYK (Nelson et al., 2007 (link)), YFP-ABD2 (Sheahan et al., 2004 (link)), GFP-CASP (Renna et al., 2005 (link)), SEC-RFP (Faso et al., 2009 (link)) and γTIP-YFP (Nelson et al., 2007 (link)). Transformation of Arabidopsis plants were conducted using floral dip method (Clough and Bent, 1998 (link)).

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.
