MASS SPECTROMETRY ANALYSIS OF MUTANT POLYPEPTIDES IN BIOLOGICAL SAMPLES

The invention relates to a method for determining the presence of at least one distinct polypeptide in a biological sample comprising contacting the biological sample with a hydrolyzing agent, wherein the hydrolyzing agent is capable of hydrolyzing the distinct polypeptide in a sequence-specific manner such that at least one distinct peptide having a predetermined peptide measured accurate mass would result if the at least one distinct polypeptide were present in the biological sample, to obtain a hydrolyzed sample; bringing the hydrolyzed sample in contact with a substrate comprising at least one immobilized binding partner, wherein the at least one immobilized binding partner is capable of specifically binding the distinct peptide; removing the hydrolyzed sample from the substrate in a manner such that the distinct peptide would remain bound to the immobilized binding partner; contacting the substrate with an elution solution, wherein the distinct peptide would dissociate from the immobilized binding partner into the elution solution; subjecting a portion of the elution solution to liquid chromatography to segregate a plurality of molecules in the portion of the elution solution to obtain sorted molecules; determining the measured accurate mass of at least one sorted molecule present in the elution solution; and determining the presence of the at least one distinct polypeptide in the biological sample when a measured accurate mass of at least one molecule is substantially equal to the predetermined peptide measured accurate mass.
