PhosphataseArrest™ I: A broad spectrum phosphatase inhibitor cocktail consisting of five phosphatase inhibitors that target serine/threonine specific, tyrosine specific and dual specificity phosphatases. PhosphataseArrest™ I is a stablised solution of sodium fluoride, sodium orthovanadate, sodium pyrophosphate, β-glycerophosphate & sodium molybdate.

PhosphataseArrest™ II: A phosphatase inhibitor cocktail consisting of five phosphatase inhibitors that target acid, alkaline and tyrosine phosphatases. PhosphataseArrest™ II contains optimised concentrations of sodium fluoride, sodium tartrate, sodium orthovanadate, imidazole and sodium molybdate.

PhosphataseArrest™ III: A phosphatase inhibitor cocktail consisting of three phosphatase inhibitors that target alkaline and serine/threonine phosphatases. PhosphataseArrest™ III is a stable, convenient 100X solution of cantharidin, bromotetramisole, and microcystin LR.
