All sections received CB-HRP immunofluorescent staining (rabbit anti-CB primary antibody diluted in 1:600, Abcam; donkey anti-rabbit Alexa Fluor 488 secondary antibody diluted in 1:200, Life Technologies). Then, the sections were mounted in sequence on the slides, counterstained by DAPI, and coverslipped. The sections of different positions were captured at uniform parameter using a fluorescence microscope (Leica DM6, Germany). The number of positive neurons was counted by the Image-Pro Plus 7.0 software. Part of the sections received CB-HRP/serotonin immunofluorescent double labeling to confirm the neurotransmitter (rabbit anti-CB primary antibody diluted in 1:600, Abcam; goat anti-serotonin primary antibody diluted in 1:600, Abcam; donkey anti-rabbit Alexa Fluor 488 secondary antibody diluted in 1:200, Life Technologies; donkey anti-goat Alexa Fluor 594 secondary antibody diluted in 1:200, Life Technologies).

After CB immunofluorescent staining (rabbit anti-CB primary antibody diluted in 1:600, Abcam; donkey anti-rabbit Alexa Fluor 488 secondary antibody diluted in 1:200, Life Technologies), the sections were sequentially mounted on slides, counterstained with DAPI, and coverslipped. The sections of the brainstem and spinal cord were visualized using fluorescence (Leica DM6, Germany) and confocal laser microscopes (Zeiss LSM 880, Germany) for different positions at the uniform standard. The cell density of CB-positive neurons (cell number/0.2 mm2 area) in each brain region was calculated using Image-Pro Plus 7.0 software. The density of CB-positive neurons was classified according to the densities: <5, 6–10, and >10, which correspond to sparse, moderate, and dense distributions, respectively.

All sections were examined with CB immunofluorescence (rabbit anti-CB primary antibody diluted in 1:600, Abcam; donkey anti-rabbit Alexa Fluor 488 secondary antibody diluted in 1:200, Life Technologies, Carlsbad, CA, USA). Sections were mounted in sequence on slides, counterstained with DAPI and coverslipped. Diencephalon sections were imaged with a fluorescence microscope (Leica DM6, Germany) and a confocal laser microscope (Zeiss, Germany). The cell density of CB-positive neurons (cell number/0.2 mm2 area) in each brain region was calculated using Image-Pro Plus 7.0 software. The density of CB-positive neurons was classified as sparse, moderate and dense according to the densities: <5, 6–10 and >10, respectively.

Immunofluorescence Staining of Calbindin

All the sections were subjected to CB immunofluorescence staining. The antisera used for immunofluorescence processing were diluted in a solution of 0.1 M PBS containing 0.3% Triton X-100. The sections were incubated in rabbit anti-CB primary antibody (1:600, Cat# ab34992, Abcam) for 48 h at 4°C. Next, the slices were incubated in donkey anti-rabbit Alexa Fluor 488 secondary antibody (1:200, Cat# A-21206, Thermo Fisher) for 2 h in the dark at room temperature. Then, the sections were mounted in sequence onto slides, counterstained with 4’,6-diamidino-2-phenylindole (DAPI), and covered with coverslips. Images of the sections of the subcortex and limbic system were captured under a fluorescence microscope (DM6, Leica, Germany) and confocal laser microscope (Zeiss, Germany). The 10× lens was used to capture the positive neurons, while the 40× lens was applied to show the detailed structures.

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.
