4-Nitrophenylmyo-inositol-1-phosphate

4-Nitrophenyl-myo-inositol-1-yl phosphate 4-Nitrophenyl-myo-inositol-1-yl phosphate is a highly specific chromogenic substrate used for the detection, quantification, and characterization of phosphoinositide phosphatases. When cleaved by the target enzyme, it generates a highly absorbing 4-nitrophenyl moiety, producing a yellow color that can be measured spectrophotometrically. This versatile substrate is valuable in examining phosphoinositide phosphatase activity, enzyme kinetics, substrate specificity, and inhibition studies in various cellular processes, including signal transduction, lipid metabolism, and membrane trafficking.
