title: A biotin-avidin technique for the localisation of membrane-bound monoclonal antibodies by low power transmission electron microscopy.
abstract: A biotin-avidin horseradish peroxidase system is described for the localisation of membrane-bound monoclonal antibodies by low power transmission electron microscopy. An indirect bridge technique was used, with a biotin-labelled goat anti-mouse immunoglobulin antibody and horseradish peroxidase-conjugated avidin D. The technique provided preparations of high morphological and ultrastructural quality which facilitated accurate cellular identification. Positive immunostaining was specific and precisely defined.
