title: Pronase pretreatment of tissue sections enhances sensitivity of the unlabelled antibody-enzyme (PAP) technique.
abstract: Treatment of dewaxed sections of formalin-fixed paraffin embedded material with 0.1% pronase for 15 min at 37 degrees C prior to the performance of the unlabelled antibody-enzyme (PAP) procedure greatly enhanced its sensitivity. This was shown by detection of immunoglobulin within plasma cells in chronic gastritis specimens.
