Protocol:
Cy-dyes were reconstituted in 100% DMF to a stock solution of 1000pmol/µL. A working solution of 400pmol/µL was prepared by further diluting the stock solution in 100%DMF. The sample pH was adjusted to 8.5 using 100mM NaOH and proteins were labeled with 8pmol of Cy-dye/µg of protein i.e. by adding 1µL Cy-dye working solution to 50µg of protein sample. Samples were incubated for 30min in the dark and on ice. The labeling reaction was quenched by adding 1µL of 10mM L-Lysine per labeling reaction and incubating 30min in the dark and on ice. The protein samples run on the same gel were pooled and a volume equivalent to 50µg of internal standard was added.
