Answer

Store iTRAQ-labeled peptides at -20 or -80 degrees Celsius. Avoid having the peptides undergo multiple freeze/thaw cycles. ITRAQ-labeled peptides can degrade over time. It is recommended that iTRAQ-labeled peptides are analyzed right after labeling, but storing the labeled peptides correctly and then analyzing a month later is also acceptable.
