Five days postfertiliation lws:PAC(H) larvae were immersed in 100 nM T3 at 8:00 AM. Before imaging, larvae were immobilized in a 2% agarose pad in a 35-mm glass-bottom dish and overlaid with 28 °C system water containing 100 nM T3, 0.02% MS-222, and 0.003% PTU. Imaging was performed with a 40× water-immersion lens using a Nikon Andor spinning-disk confocal microscope equipped with a Zyla sCMOS camera running Nikon Elements software. Time course began at 4:00 PM and lasted for 9 h total. Images were captured at 30-min intervals. A 3-μm step z-series covering the area of interest was converted into volume view using the Nikon Elements software. The Director feature in Nikon Elements software was used to create the time-lapse movie (Movie S1).

Laser Confocal Microscopy Imaging Protocol

All microscopy was performed on a laser-scanning confocal microscope (A1R; Nikon) using a 20 × water objective lens (live imaging) or a 60 × oil Plan-Apochromat objective lens with a 1.4 NA (fixed imaging). Nikon Elements Software was used for all acquisition and image processing. For all fixed images, multiple z planes were visualized in 0.4 μm steps (4–10 μm total depth). For live imaging, a 20 μm range was imaged with 0.5 μm steps. Images were acquired every 10 minutes for the duration of the time lapse. Images are maximum intensity projections of z stacks. Images were processed in Nikon Elements Software.

Whole, fixed lws:PAC(H) adult retinas, cryosections of lws:PAC(H) eyecups, and HCR-processed, adult (0.5–1.5 years) WT retinas were mounted in glycerol and imaged with a 20× dry lens using a Nikon–Andor spinning disk confocal microscope and Zyla sCMOS camera running Nikon Elements software (RRID:SCR_014329), and 3 µm-step sizes were used for Z-series images. Z-stacks were flattened by max projection, and brightness/contrast adjusted in FIJI (ImageJ) (RRID:SCR_002285). Multiple images encompassing the entirety of whole retinas or whole cryosections were stitched together using the “large stitched image” feature in Nikon Elements software.

Cardiomyocyte Size Analysis Protocol

Unfixed slides with the transversally cross-sectioned heart were incubated for 1h with blocking buffer (PBS with 2% BSA and 0.1% Triton X-100) prior to overnight immunostaining at 4°C with rat anti-laminin α2 (4H8–2; Santa Cruz, cat. no. sc-59854) and AlexaFluor635-conjugated phalloidin (Invitrogen, cat. no. A22284). The slides were washed and incubated with anti-rat AlexaFluor488-conjugated IgG (Invitrogen, cat. no. A48262). DAPI (Sigma Aldrich, cat. no. 10-236-276-001) was used to identify nuclei.
For the analysis of cardiomyocyte size, the left ventricle of the heart was identified and imaged on the Nikon C2 confocal microscope with a 20X objective. Phalloidin was used to classify the individual cardiomyocytes (red), while the inverse threshold of laminin α2 was used to determine cardiomyocyte boundaries. Cardiomyocyte size was determined with the Nikon Elements software by using the intersection of inverse laminin and the phalloidin staining. Cardiomyocytes with an area of <100 and >1000 μm2 were excluded. The Feret’s minimal diameter was used to measure cardiomyocyte size and this analysis was performed by using the Nikon Elements software and the “Object Count” function.

Check if the same lab product or an alternative is used in the 5 most similar protocols
This specialized invasion assay was performed according to previously published protocols (24 (link), 25 ). Assays were performed in 96-well plates (Black wells, clear bottom, PerkinElmer). Briefly, ice-cold serum-free liquid bovine collagen (PureCol) was prepared at 1 mg/ml concentration. After trypsinization, the cells were added to the collagen suspension at a final concentration of 5×104cells/ml, and 100 µl aliquots were dispensed into five replicate wells. The cells were subsequently spun down, then incubated in a 37°C/5% CO2 tissue-culture incubator to allow the collagen to solidify. Finally, the collagen plug was covered by 30 µl of a mixture of the appropriate culture medium diluted 1:1 with PBS. After 48 hours, the cells were fixed with 4% PFA (final concentration) and stained with 10 µg/ml Hoechst-33342. Images of nuclei staining were obtained on an inverted microscope operated by Nikon Elements Software using a 20× air objective. Twenty-five adjacent images covering ~85% of the well area were taken from 0 µm (bottom of the plate) to 150 µm up in the collagen plug, at 25 µm steps. Quantification of nuclei/well was obtained using the “object count” feature of Nikon Elements Software. Invasion ratio was calculated as the sum of cell counts at 50, 75, 100, 125 and 150 µm over cell counts at 0 µm.

Stereological Quantification of Dopaminergic Neurons

Check if the same lab product or an alternative is used in the 5 most similar protocols
Stereology was initially performed on serial sections from the midbrain following a protocol adapted from Tapias et al. 201467 (link). Briefly, tissue was immunolabeled for TH, MAP2, and DAPI and imaged at ×20 on a Nikon90i fluorescent microscope in the Center for Biologic Imaging at the University of Pittsburgh. Images were analyzed in Nikon Elements software counting the number of dopaminergic neurons determined by overlap between DAPI, MAP2, and TH within a region of interest defining the substantia nigra pars compacta as previously described67 (link). Subsequent experiments were performed with a modified method of stereology utilizing overlap between TH and fluorescent Nissl (NeuroTrace 647, Life Technologies) within the substantia nigra pars compacta as previously described68 (link),69 . These images were obtained on an Olympus BX61VS slide scanning microscope, and analysis was performed utilizing Nikon Elements software.

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.
