Left: Visualization of tyrosine hydroxylase expression in rat brain by Immunofluorescent analysis. Section was stained with chicken anti-TH antibody, C-2126-100, (green, 1:5,000) and Hoechst staining of nuclear DNA (blue). Product C-2126-100 stains the dopaminegic TH-positive neurons and their processes of the substantia nigra. Right: Western blot analysis of tissues and lysates using C-2126-100 (green, 1:50,000) with a band at approx. 58kDa in brain tissue lysates. Lane 1: protein standard (red); Lane 2: rat brain caudate/putmen region; Lane 3: rat brain midbrain; Lane 4: whole mouse midbrain; Lane 5: cow midbrain segment.
