The brain-like tissues were fixed with 4% paraformaldehyde for an hour and washed with 1× phosphate-buffered saline (PBS) 3 times at 5-min intervals. After being incubated in 1× PBS with 5% goat serum (AR0009, Boster, USA), a primary antibody diluted 1:200 and 0.3% Triton X-100 (T8200, Solarbio) overnight at 4 °C, the tissues were washed with 1× PBS 6 times at 10-min intervals and then incubated in 1× PBS with 5% goat serum, a secondary antibody diluted 1:200 and 0.3% Triton X-100 for 4 h before DAPI (AR1176, Boster) was added for an additional 10 min. Finally, the tissues were washed 6 times in 1× PBS at 10-min intervals and observed under an LSCM. All antibodies used are summarised in Table 2. The LSCM software NIS-elements AR was used for measuring and counting the length and the number of axons and dendrites.

Immunofluorescence Analysis of TGF-β2 Induced EMT

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cells (1×105 cells/well) were seeded on an 8×8 mm cover slip in 24-well plates, starved overnight and then treated with 3 ng/ml TGF-β2. Following 48 h of treatment, the cells were fixed with 4% paraformaldehyde for 20 min and washed 3 times with PBS. The cells were permeabilized in PBS with 0.3% Triton X-100 for 5 min. The cells were then blocked with 5% normal goat serum for 1 h. Primary rabbit anti-human α-SMA antibody (1:500, ab5694) and rabbit anti-human E-cadherin antibody (1:1,000, ab53226) (both from Abcam, Cambridge, MA, USA) were incubated with the cells overnight at 4°C. After being rinsed extensively, the cells were exposed to the fluorescent secondary antibody (goat anti-rabbit Cy3, 1:10,000, CW0114S; goat anti-rabbit FITC, 1:10,000, CW0159S; both from CWBIO, Beijing, China) in the dark for 30 min. The coverslips were rinsed again with PBS 3 times and mounted with DAPI for 5 min, as a nuclear counterstain. Finally, the cells were observed under a fluorescence microscope (DP71; Olympus, Tokyo, Japan).

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.
