Tuj1 anti tubulin beta 3 isoform

The cells were fixed with 4% paraformaldehyde (PFA) for 15 min at room temperature (RT). Fixed cells were permeabilized and washed with TPBS containing 0.1% TritonX-100 (Sigma) in phosphate-buffered saline (PBS) and blocked with 5% normal horse serum (Vector Labs) for 30 min at RT. Afterwards, they were incubated with primary antibodies in blocking solution overnight with gentle rocking at 4℃. After washing three times with TPBS, they were incubated with secondary antibodies (ThermoFisher) for 90 min at RT, and then were counterstained using DAPI for 15 min. All fluorescence images were captured by confocal microscopy (TCSSP5II, Leica). The following primary antibodies were used: anti-OCT4 (1:200, Santa Cruz), anti-SOX2 (1:200, Millipore), anti-NANOG (1:200, R&D Systems), anti-SSEA-4 (1:100, Developmental Studies Hybridoma Bank)), anti-TRA-1-81 (1:100, CHEMICON), Tuj1 anti-tubulin beta III isoform (1:200, Millipore), anti-SMA (1:100, DAKO); anti-AFP (1:100, DAKO), anti-Nestin (1:200, R&D Systems), anti-Musashi (1:200, Millipore), anti-Map2 (1:200, Millipore), anti-TBR1 (1:100, Abcam), anti-CTIP2 (1:100, Abcam), 6E10 anti-Amyloid β (1:500, Covance), AT8 anti-p-tau (1:1000, ThermoFisher), anti-ChAT (1:200, Millipore) and anti-LC3B (1:500, Cell Signaling).
