What is ISO-OMPA?
The Uses of ISO-OMPA
Tetraisopropyl pyrophosphoramide has been used:
- as a butyrylcholinesterase inhibitor to determine the proportions of butyrylcholinesterase (BChE) in cat and tiger plasma
- to inhibit wild-type BChE in acetylcholinesterase assay
- to selectively block the enzymatic activity of AChE
