Abcam's Choline/Acetylcholine Assay Kit provides a simple and sensitive means for quantifying Choline and Acetylcholine by either a colorimetric or fluorometric method. In the assay free choline is oxidized to betaine, via the intermediate betaine aldehyde. The reaction generates products which react with the Choline Probe to generate color (λ= 570 nm), and fluorescence (Ex/Em 535/587 nm). Acetylcholine can be converted to choline by adding acetylcholinesterase to the reaction. The kit can detect choline and acetylcholine (total choline – free choline) in various biological samples such as in blood, cells, culture media, fermentation media, etc. There is no need for pretreatment or purification of samples. The kit can detect ~10 pmol-5 nmol of choline or acetylcholine.

Choline and acetylcholine play important roles in many biological processes. Choline is an essential nutrient, commonly grouped with the B complex vitamins, that plays key roles in many biological processes. Choline is a precursor for the synthesis of acetylcholine (AchE), a critical neurotransmitter in both the periferial and central nervous systems.

|Functional Studies||Use at an assay dependent dilution.|
Choline measured in mouse tissue lysates showing quantity (nmol) per mg protein of tested sample
Choline measured in cell lysates showing quantity (pmol) per 1 mln of tested cells
Choline measured in biological fluids showing quantity (nmol) per mL of tested sample
Standard curve (colourimetric) : mean of duplicates (+/-SD) with background readings substracted
Choline/Acetylcholine Standard Curve (colorimetric reading): Assays were performed following the kit instructions. The diamonds are generated using choline as the substrate, whereas the open and closed circles were generated using acetylcholine as substrate in the presence and absence of acetylcholinesterase.
