Quantifying Retinal Brn3a-Positive Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
At 12, 24, and 48 h after treating the eyes with NMDA or PBS, whole retinas were isolated (three cohorts of six, n = 18) and immunostained with antibody against Brn3a (1:100 dilution) according to the methods published from this laboratory [25 (link)]. Digitized images of the whole retina was obtained by using a Zeiss Imager.Z2 microscope and compiled by using Adobe Photoshop Software 7.0 (Adobe Systems Incorporated, CA). The number of Brn3a-positive cells in each retina was quantitated in four areas of equal size from the optic disc (Boxed areas, 900 x 800 um size, 20x magnification) by using Nikon Elements AR software (Nikon Instruments Inc., Melville, NY). Statistical significance was determined by ANOVA, followed by a post hoc-Tukey’s test (GB-Stat Software, Dynamic Microsystems, Silver Spring, MD) and the results were expressed as the mean ± SEM.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunofluorescence staining of zebrafish skeletal myofibers was performed by adapting a protocol previously described84 (Supplementary Note). Myofibers were incubated in primary antibody overnight at 4 °C, washed in 1x Phosphate-Buffered Saline with 0.1% Tween 20 (PBST), then incubated with goat anti-mouse Alexa Fluor 488 secondary antibody (Thermo Fisher Scientific, A11001; 1:500) and goat anti-rabbit Alexa Fluor 594 secondary antibodies (Thermo Fisher Scientific, A11037; 1:250) for 1 h at room temperature. Further washing in PBST was performed before mounting with Vectashield Mounting Medium (Vector Laboratories). Primary antibodies used were rabbit polyclonal anti-sarcomeric α-actinin (Cell Signaling Technologies, 3134; 1:25) and mouse monoclonal anti-titin (Merck, T9030; 1:200). Digital images were captured with Newcastle University Bioimaging Unit’s Nikon A1R point scanning confocal microscope (Nikon) using Nikon Elements AR (v5.21.03).

Agar Pad Microscopy for Time-Lapse Imaging

Check if the same lab product or an alternative is used in the 5 most similar protocols
2% LB agar was cut into approximately 10 mm × 10 mm squares and inoculated with 1 µl of liquid culture. The pad was then wedged, in a glass-bottomed dish (P35G-1.5-20-C; MatTek Corp.), between two plastic coverslips (Rinzl Plastic Coverslips, Size 22 × 22 mm; Electron Microscopy Science) manually bent in half at a 90° angle. Thus, half of each plastic coverslip made contact with the bottom of the dish, while the other half made contact with the agar pad. After placing a drop of approximately 50 µl of water on top of each plastic coverslip to maintain humidity in the dish, the MatTek dish was sealed with parafilm (this setup is illustrated in Fig. 1A). Cells (Table 1) were grown for approximately 6 h at room temperature (approximately 23°) during a timelapse acquisition on a Nikon TE 2000 microscope equipped with an Orca ER camera, a 20 × phase contrast objective, and Perfect Focus. A large area of the sample was composited with automatic image stitching by Nikon Elements AR. Areas toward the center of the pad were selected for imaging.

A 1:12 series of sections containing the SNpc was washed 4 × 5 min in TBS (pH 7.3), mounted on subbed slides, and allowed to dry for at least an hour. Samples were incubated for 25 min in 0.5% potassium permanganate (Sigma-Aldrich, 223468) in TBS to quench autofluorescence. Sections were washed in TBS, destained 3 min in 0.2% potassium disulfite (Sigma-Aldrich, P2522) and 0.2% oxalic acid (Sigma-Aldrich, 75688) in TBS, and stained for 3 min in 0.0125% thioflavin-S in 40% ethanol/60% TBS (Sigma-Aldrich, T1892). Sections were differentiated in 50% ethanol/50% TBS, washed 5 × 5 min in TBS, washed 3 × 5 min in ddH2O, and coverslipped with Vectashield hard set mounting media (Vector Laboratories, H-1400). Images were taken with a Nikon Eclipse 90i microscope with a QICAM camera (QImaging, Surrey, British Columbia, Canada), using Nikon Elements AR (Version 4.50.00, Melville, NY) software.

For experiments with kinetoplast staining, MitoTracker® Red was added to the culture at 500 nM and shaken at 27 °C for 30 minutes to allow uptake. Cells were harvested for microscopy at 2–5 × 106cells/mL and washed twice in PBS before suspending in 3.7% formaldehyde/PBS solution and 100 μl of suspension was fixed to glass slides for 10 minutes. Cells were washed three times in PBS, permeabilized with 0.1% Triton X-100 and washed an additional three times in PBS. Blocking was performed for 60 minutes using 5.5% FBS supplemented with 0.05% Tween 20 in PBS. All incubation steps were performed in humid chamber and all antibodies were used at concentrations indicated in text. Cells were stained using 100 uL 1 μg/mL DAPI solution for 1 minute and washed three times with PBS. Cells were air dried and mounted using Vectashield® before imaging was performed using a Nikon Ti microscope. Image analysis was performed using ImageJ (NIH) and Nikon Elements AR.

Primary Hippocampal Neuron Transfection Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Primary cells were harvested from the hippocampi of E18 Sprague-Dawley rat pups obtained from Charles River Laboratories. Hippocampal tissue was digested using papain and mechanical trituration. Cells were plated onto poly-ornithine/laminin coated 24-well plates with a density of approximately 100,000 per well. Cells were cultured in medium composed of 50/50 DMEM/F12, 0.5× N2 and 0.5× B27 supplements. 1% Penicillin/Streptomycin was added to the medium for the first 36 hours following harvest and subsequently removed 4 hours before transfection to avoid adverse effects on lipid-based delivery vehicles. Transfections were carried out by adding 20 μL of the lipidoid-RNA complex (containing a total of 0.5 μg RNA) to each well and incubating the primary hippocampal cultures at 37°C for 24 hours. After incubation, mCherry expression was observed via fluorescence imaging with 10X magnification, and the images were analyzed using Nikon Elements AR.

Fixed brains were frozen on a sliding microtome and sliced at 40 μm. Free-floating sections were stored in cryoprotectant (30% sucrose, 30% ethylene glycol, 0.05M PBS) at −20°C. A 1:4 series was used for staining. Nonspecific staining was blocked with 10% normal goat serum. Sections were then incubated overnight inappropriate primary antibody: pSyn (Abcam, Ab184674, 1:10,000) or TH (Millipore, AB152, 1:4,000). Primary antibodies were prepared in Tris-buffered saline with 1% NGS/0.25% Triton X-100. Sections were incubated with appropriate biotinylated secondary antibodies at 1:500 (anti-mouse, Millipore AP124B or anti-Millipore AP132B), followed by Vector ABC standard detection kit (Vector Laboratories PK-6100). Visualization was performed using 0.5 mg/ml 3,3’ diaminobenzidine (DAB, Sigma-Aldrich) for 30-60 seconds at room temperature and enhanced with nickel. Slides stained for pSyn were counter-stained with Cresyl violet. Slides were dehydrated before cover-slipping with Cytoseal (Richard-Allan Scientific) and imaged on a Nikon Eclipse 90i microscope with a QICAM camera (QImaging) and Nikon Elements AR (version 4.50.00).

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.
