Shotgun electroelution: a proteomic tool for simultaneous sample elution from whole SDS-polyacrylamide gel slabs

Electrophoresis. 2007 Feb;28(4):508-11. doi: 10.1002/elps.200600634.

Abstract

A high-throughput device has been constructed which allows parallel electroelution of separated SDS-protein bands directly from intact unsectioned polyacrylamide gel slabs as well as single electroelution of certain protein spots into a 384-well standard flat-bottom multiwell plate. The prototype provides complete, quick elution for proteomics from 1-D or from 2-D gels without gel sectioning. Since the elution chamber matrix requires no assembly, sample handling can be easily carried out by existing robotic workstations. The current design is a good candidate for automation of spot elution since there are no moving liquid containing components in the apparatus. Eight SDS-proteins were eluted in test runs and an average 70% sample recovery was achieved by re-electrophoresis of the electro-eluates.
