One-dimensional thin-layer chromatography on polyamide plates offers an easy and rapid identification of O-phosphotyrosine. The thin-layer plate is developed for 30 min in 5% propionic acid containing 0.013%-0.025% sodium dodecyl sulfate. O-Phosphotyrosine, with Rf = 0.54, can be well separated from O-phosphothreonine and O-phosphoserine, which comigrate at Rf = 0.72.
