説明
Lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P) are growth factor-like bioactive lipids having a phosphate monoester residue. Phos-tag can bind to them and be used both for purification and quantification. In a two-phase solvent system consisting of chloroform/methanol/water, addition of Phos-tag move LPA and S1P from a hydrophilic phase to a hydrophobic phase in the form of their Phos-tag complexes. Using this property, we developed a method for purification of LPA and S1P in biological materials by the phase separation technique. Advantages of use of Phos-tag for detection of LPA and S1P in MALDI-TOF MS are an increase in ionization efficiency and detection as a single-ion form. Homologues of LPA and S1P in natural samples can be quantified by MALDI-TOF MS by using internal standards.<br>
