4.1.4 Equipment

4.1.5 Protocol

Temperature: 25 °C.

Duration: 15 min.

Protocol:
The mineral oil was removed from the IPG strips by placing them (gel side up) onto a piece of dry filter paper and blotted with a second piece of wet filter paper. 5 ml reduction buffer was added to the channeled tray. IPG strips (gel side up) were transfer into the tray. The tray was placed on an orbital shaker and gently shakes for 15 m.

4.1.5 Protocol

Temperature: 25 °C.

Duration: 15 min.

Protocol:
The reduction buffer was removed carefully by decanting the liquid from the tray. 5 ml alkylation buffer was added to each IPG strip. The tray was kept on the orbital shaker for 15 min.
