Abstract
A method for the utilization of dried polyacrylamide gels from the pre-proteomic era is described in order to
enable the mass spectrometric analysis of long-term stored protein preparations. The in-gel digestion of highmolecular-mass proteins embedded in a 20-year old gel was carried out following gel re-swelling and resulted in
the proteomic identification of a large number of proteins, including 3400 kDa titin, 800 kDa nebulin and
myosin heavy chains of 220 kDa from rabbit skeletal muscle. These findings demonstrate that dried protein gels
from past biochemical analyses can be successfully reused and analyzed by modern and refined mass spectrometric techniques.
