Choline Acetyltransferase/ChAT in Human Brain. Choline Acetyltransferase/ChAT was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using 15 µg/mL Goat Anti-Human Choline Acetyltransferase/ChAT Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3447) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Background: Choline Acetyltransferase/ChAT
ChAT catalyzes the production of the neurotransmitter acetylcholine (Ach), which is required for cholinergic neuron communication. It serves as a marker for functional cholinergic neurons in the central and peripheral nervous systems. At least six ChAT mRNAs encoding 69 kDa, 82 kDa and 74 kDa ChAT proteins have been identified. Compared to the 82 kDa form, 69 kDa ChAT lacks the N-terminal 118 amino acid extension containing a nuclear localization signal. As a result the 69 kDa ChAT is primarily localized to the cytoplasm. Human 69 kDa ChAT shares 86% amino acid sequence identity with the mouse or rat ChAT.
