Methods for measuring concentrations of biomolecules in biofluids

摘要

The present invention provides methods for measuring the absolute concentration of Tau, and other protein, peptide fragments and proteoforms in CSF and plasma samples collected from a subject. Such biomolecules may be implicated in one or more neurological and neurodegenerative diseases or disorders. Also provided is a method for determining whether a therapeutic agent affects the CSF or plasma concentration of a central nervous system derived biomolecule. Also provided are kits for performing the methods of the invention.
