Document Type and Number:
WIPO Patent Application WO/2023/228497
Kind Code:
A1
Abstract:
Provided are: a method which is for analyzing a neurogranin-related peptide and can suppress deviations in analysis results; and a method for preparing a biological sample containing the neurogranin-related peptide used for same. A method for preparing a sample solution containing a neurogranin-related peptide involves mixing a biological sample containing the neurogranin-related peptide with an organic solvent having a relative polarity of 0.200 to 0.700 to prepare a sample solution containing the organic solvent having a final concentration of at least 5.0 (v/v)%.
