Cell Biolabs’ Acetylcholine Assay Kits are a simple fluorometric or colorimetric assay that measures the amount of acetylcholine present in plasma or serum, tissue homogenates, or cell suspensionsin a 96-well microtiter plate format. Each kit provides sufficient reagents to perform up to 96 assays, including blanks, acetylcholine standards and samples. Sample acetylcholine concentrations are determined by comparison with a known acetylcholine standard.
