ABSTRACT:
An integrated proteomics sample preparation device and method for in-gel digestion of proteins and for desalting and concentrating samples prior to further analysis such as by MALDI TOF and/or electro-spray ionization (ESI) mass spectrometry. The device and method of the present invention allow for digestion, desalting and concentration of sample prior to analysis. More specifically, the device in accordance with an embodiment of the present invention includes a plurality of wells in fluid communication with a an outlet or drainage opening containing a three dimensional structure comprising a plurality of sorptive particles entrapped in a porous polymer matrix so as to form a device capable of carrying out solid phase extraction. In a preferred embodiment, the wells are configured so as to prevent a sample carrier present in the wells from clogging the outlet when subjected to a driving force such as vacuum. The device also reduces or eliminates overflowing of a well in the event a drain becomes clogged during automated operation.
