Title:
被分析物の分析方法
Document Type and Number:
Japanese Patent JP4606028
Kind Code:
B2
Abstract:
Provided is a method for characterizing an analyte by matrix assisted laser desorption ionization (MALDI) mass spectrometry, which method comprises: (a) labelling the analyte with a light-absorbing label that absorbs light at a pre-determined frequency, to form a labelled analyte; (b) embedding the labelled analyte in a matrix formed from at least one compound that absorbs light, to form an embedded labelled analyte; (c) desorbing the embedded labelled analyte by exposing it to light having the pre-determined frequency, to form a desorbed analyte; and (d) detecting the desorbed analyte by mass spectrometry to characterize the analyte.
