Biological Activity

Description

In Vitro

Chlorophenol Red reacts with chlorine dioxide to form a colorless product^[1].
Chlorophenol Red is hydrolyzed by β-galactosidase and undergoes electrochemical oxidation to generate an adsorbed 1,2-quinone intermediate^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
