Chemical structure of POPSO

GC67472

POPSO

Also known as 2-hydroxy-3-[4-(2-hydroxy-3-sulfopropyl)piperazin-1-yl]propane-1-sulfonic acid

POPSO is a zwitterionic buffer, increases osmolality and shows marked inhibition of anion uniport· POPSO inhibits chloride uniport with an IC50 value of 24 mM· POPSO enhances copper uptake and toxicity in alga, impairs mitochondrial inner membrane· The working pH range of POPSO sesquisodium salt is 7·2-8·5
