ab167579 staining zebrafish retina sections by IHC-Fr. The tissue was fixed with paraformaldehyde and an antigen retrieval step was performed with sodium citrate pH 6. Blocking of the sample was done with 5%BSA in PBS containing 01% Tween 20 and 0.5% Triton X, for 60 minutes at 23°C, followed by staining with ab167579 at 1/100 in blocking solution for 16h at 4°C. An alexa 488 conjugated goat anti-mouse polyclonal antibody at 1/1000 was used as the secondary antibody. Nuclei are stained in blue with DAPI. RS1 expression can be observed in bipolar cells (in green).See Abreview
