title: Efficient elution of purified proteins from polyvinylidene difluoride membranes (Immobilon) after transfer from SDS-PAGE and their use as immunogens.
abstract: Following separation of proteins by SDS-PAGE, they are electroblotted onto polyvinylidene difluoride membranes (Immobilon). Protein bands of interest are excised, and the proteins are eluted from the membrane with detergent-containing buffers at pH 9.5. The method routinely yields recovery of 70-90%, and this is independent of protein molecular weight.
