ABSTRACT:
Immobilized pH gradient (IPG) strips are encapsulated in an enclosure that seals the strip from atmospheric exposure and yet contains sufficient volumetric capacity to accommodate the strip in rehydrated form. The enclosure contains a pair of electrode access apertures each of which is spanned by a dialysis membrane to permit electrical contact between external electrodes and the encapsulated IPG strip, and one or more sample application apertures through which liquid sample can be applied to the strip. Each of the apertures is covered by a protective cover or flap that is removable to expose the aperture.
