The Human Urinary Proteome Fingerprint Database UPdb
Table 2
Overview of SELDI-TOF spectra available as part of the database. Spectra were recorded using low laser energy desorption (m/z range 1500 to 25000) and high laser energy desorption (m/z range 20000 to 150000) from 200 nonredundant samples. Peak clusters common in all spectra of one chip-type were analysed using a 5% signal-to-noise cutoff, and numbers of peaks found in at least 10% or 20% of all spectra were counted.
Chip-type
Chip specificity
Number of spectra recorded in the low mass range (1500–25000)
Number of spectra recorded in the high mass range (20000–150000)
Demographic distribution (number of patient samples analysed which are healthy/cancer pre-op/disease-free cancer post-op)
Number of peaks above threshold in all samples
Number of common peaks above threshold in 10% of all samples
Number of common peaks above threshold in 20% of all samples
