METHOD FOR DETERMINING BIOSPECIMEN QUALITY

摘要

A method of assigning an index which indicates the degradation of a type-specific sample, comprising: providing a first specimen of a type-specific sample, subjecting the first specimen to condition(s) which degrade protein(s) in the first specimen; performing surface- enhanced laser desorption/ionization time-of-flight mass spectroscopy analysis on the first specimen to determine protein peak intensities for individual proteins in the first specimen; based on the protein peak intensities, identifying protein(s) in the first specimen as having degraded or not degraded; and assigning an index which is derived from a ratio of the degraded protein(s) to the non-degraded protein(s).
