Phosphatase Substrate Sets

JPT Peptide Technologies offers an efficient way to study phosphatase activity and substrate specificity. Our Phosphatase Substrate Sets each include a 384-well microtiter plate containing 360 phospho peptides as phosphatase substrates (250 pmol per well) derived from human phosphorylation sites, together with 10 calibration standards. The assay procedure is easy to perform: Subsequent to incubation with target phosphatase, the released phosphate ions can be detected by phosphate-binding dyes like molybdate or malachite green to identify positive phosphatase substrates.
