PH-THPP exhibits concentration dependent blocking activity.
By Eleanor Baxter on 10/29/2018
Assay Type: In Vitro
Species: Human

A very potent K2p channel blocker which was used to figure out the blocking activity as concentration of the blocker molecule increased. PK-THPP is a great antagonist molecule which shows channel obstructing properties which is concentration dependent.
