Title:
METHOD FOR IDENTIFYING AND QUANTIFYING TYPES OF ANIMAL HAIR
Document Type and Number:
WIPO Patent Application WO/2013/154208
Kind Code:
A1
Abstract:
The present invention addresses the issue of providing a method which enables the identification and quantification of types of animal hair from a sample containing animal hair by directly analyzing protein which is the main component of animal hair, rather than using DNA which is present in small quantities. The present invention provides a method in which mass spectrometry of an animal hair sample is carried out, enabling, as a result of the analysis, the mass, mass/charge ratio (m/z), LC elution time for the mass/charge ratio, and a partial sequence useful as a marker to be identified for protein components such as keratin which are the main protein components of animal hair, and types of animal hair to be identified and quantified on the basis of these results.
