Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of pan Arrestin showing staining in the cytoplasm and nucleus of paraffin-treated human cerebellum tissue (right) compared with a negative control in the absence of primary antibody (left). Antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then incubated with ab2914 diluted by 3% BSA-PBS at a dilution of 1:500 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.
