如果只有几皮摩尔的样品，则很难通过生化方法测定肽的硫酸化。通过改变激光辐照度，获得了含有诊断硫酸盐化的碎片离子的基质辅助激光解吸/电离质谱。
Determination of sulfation on peptides is difficult by biochemical methods if only a few picomoles of sample are available. By varying the laser irradiance, matrix-assisted laser desorption/ionization mass spectra were obtained containing fragment ions diagnostic of sulfation.
