A new microchannel device for proteins separation and detection

摘要

A new micro-channel protein separation device, which is easy to separate proteins from a mixture and includes an in-situ protein detection set up, has been fabricated. An example of separating two proteins from a mixture within 15 min using a low electric field of 20 V/cm is demonstrated. The separated protein was confirmed by the staining method and electron spectroscopy for chemical analysis (ESCA). This device is potentially applicable to the separation of a wide range of biomolecules.
