Propionylthiocholine iodide

Propionylthiocholine iodide serves as a substrate for detecting the activities of acetylcholinesterase and pseudocholinesterase. Propionylthiocholine iodide acts as a substrate for intestinal epithelial cell-derived acetylcholinesterase and is resistant to hydrolysis by this enzyme.

Biological Activity

Description

All Cholinesterase (ChE) Isoforms :

AChE
BChE

In Vitro

Propionylthiocholine iodide (37°C) exhibits pseudocholinesterase activity of 3261 U/l and acetylcholinesterase activity of 3928 U/l in human whole blood, yielding an acetylcholinesterase-to-pseudocholinesterase ratio of 1.20^[1].
Propionylthiocholine (1 mM) iodide is a poor substrate for the predominantly AChE activity present in Caco-2 human intestinal epithelial cells, with significantly lower hydrolytic activity observed compared to acetylthiocholine^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
