RT-PCR for beta-galactosidase expression in brain extracts. Beta-gal mRNA is expressed in PTPH1-KO cerebellum, cortex, hippocampus and substriatal regions (midbrain, thalamic nuclei, pontine region); no beta-gal expression detected in WT brain extracts (first lane of each block); histone H2A gene was used as positive control (second lane).
