摘要
Disclosed is that the most crucial point in the quantitative analysis of MALDI-TOF MS is to minimize quantitative variances (RSDs, relative standard deviations) of peak intensities of obtained spectrum data. The minimized RSD is translated into improved reproducibility of the data and finally leads to high accuracy of the results. Several technical procedures based on the concept of automatization to reduce the RSDs (to less than 10%) in the MALDI-TOF MS of serum glycans were proposed for the preparation steps of extracting the targeted glycans from human blood and sample loading processes onto the plates. The presented techniques described in the examples proved the contributions of the present invention to enhanced reproducibility of the MALDI-TOF MS and consequently to improved screening accuracy for the differentiation of the benign ovarian tumor patients from the borderline ovarian tumor patients in comparison with accuracy of differentiation based on other analysis methods.
