Choline/Acetylcholine Assay Kit (ab65345) provides a simple and sensitive means for quantifying Choline and Acetylcholine by either a colorimetric or fluorometric method in samples such as blood, cells, culture media, fermentation media, etc.

In the choline / acetylcholine assay protocol, 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 to measure total choline (choline + acetyl choline). The amount of acetyl choline is calculated by subtracting choline from total choline.

There is no need for pretreatment or purification of samples. The kit can detect ~10 pmol-5 nmol of choline or acetylcholine.

Cells should be cultured in choline chloride free medium.

Choline / acetylcholine assay protocol summary:

- add samples and standards to wells

- add choline reaction mix with, or without, acetylcholinesterase, and incubate for 30 min at room temp

- analyze with microplate reader
