Mass Spectra Identification
Calculation of a matching score based on: Rel Score
% matches of the reference spectrum (e.g. 6 / 10 = 0.6)
Rel P-Num. % matches of the unknown spectrum (e.g. 6 / 20 = 0.3)
I-Corr. value of intensity correlation
Cancer Drug Resistance
Microbiota Analysis
based proteomic analysis
Gene Editing Tools
Identified species
Unknown microrganism
Generate MALDI-TOF profile spectrum
analyzed by MS
