The present invention provides a method for labelling one or more analytes in a sample, the method comprising: a) contacting the sample with one or more bifunctional linker reagents having the general formula Re
1
-L
1
-Re
2
, wherein Re
1
is a first reactive group, L
1
is a linker moiety and Re
2
is a second reactive group, wherein Re
1
reacts with an analyte to form a modified analyte; and b) contacting the sample with one or more mass labels, wherein Re
2
of the bifunctional linker attached to the analyte reacts with a mass label to form a labelled analyte, wherein each mass label is relatable to an analyte by mass spectrometry.
