Chitosan maldi tof analysis
WebMatrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry is the primary identification method. Ancillary testing (ie, 16S gene sequencing, ITS gene sequencing, conventional biochemicals) will be employed as required. WebThe MALDI-TOF analysis is limited to molecular weights higher than 500 Da because of matrix signal interference; therefore, DP < 2 oligomers could not be determined by this method.
