Abstract
A method for removing liquid from a gel matrix including the steps of providing a hydrophobic water vapor-permeable membrane adapted to transmit water vapor and to resist passage of liquid water by capillary diffusion. The membrane and gel matrix are contacted together and subjected to a vacuum to remove water vapor from the gel matrix through the membrane. Liquid is removed from the gel matrix, and the gel matrix simultaneously adheres to the membrane.
Claims16
A method for removing liquid from an electrophoresis gel matrix comprising the steps of:
- providing a water vapor-permeable membrane adapted to transmit water vapor and to resist passage of liquid water by capillary diffusion, said membranes being hydrophobic,
- contacting said gel matrix with said membrane, and
- subjecting said gel matrix and membrane to a vacuum to remove water vapor from said matrix through said membrane, whereby liquid is removed from said matrix and said matrix adheres to said membrane.
A gel matrix comprising material electrophoresed within said matrix adherently fixed to a water vapor-permeable membrane adapted to transmit water vapor and to resist passage of liquid water by capillary diffusion, said membrane being hydrophobic.
